Job Description CoreWeave is The Essential Cloud for AI™. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence. Trusted by leading AI labs, startups, and global enterprises, CoreWeave combines superior infrastructure performance with deep technical expertise to accelerate breakthroughs and turn compute into capability. Founded in 2017, CoreWeave became a publicly traded company (Nasdaq: CRWV) in March 2025. Learn more at www.coreweave.com. Weights & Biases at CoreWeave CoreWeave acquired Weights & Biases to create the most powerful end-to-end platform to develop, deploy, and iterate AI faster. CoreWeave operates a growing footprint of data centers covering every region of the US and across Europe, and was ranked as one of the TIME100 most influential companies of 2024. By bringing together CoreWeave's industry-leading cloud infrastructure with the best-in-class tools AI practitioners know and love from Weights & Biases, we're setting a new standard for how AI is built, trained, and scaled. The integration of our teams and technologies is accelerating our shared mission: to empower developers with the tools and infrastructure they need to push the boundaries of what AI can do. From experiment tracking and model optimization to high-performance training clusters, agent building, and inference at scale, we're combining forces to serve the full AI lifecycle — all in one seamless platform. Weights & Biases has long been trusted by over 1,500 organizations — including AstraZeneca, Canva, Cohere, OpenAI, Meta, Snowflake, Square, Toyota, and Wayve — to build better models, AI agents and applications. Now, as part of CoreWeave, that impact is amplified across a broader ecosystem of AI innovators, researchers, and enterprises. As we unite under one vision, we're looking for bold thinkers and agile builders who are excited to shape the future of AI alongside us. If you're passionate about solving complex problems at the intersection of software, hardware, and AI, there's never been a more exciting time to join our team. About the Role Training a frontier model is as much an infrastructure problem as it is a modeling problem. When a run fails at hour 47 of a 72-hour job, the question is almost never "what's wrong with the code" — it's "what happened on the cluster." Node failures, network timeouts, storage bottlenecks, and scheduling decisions determine whether training runs succeed or fail, how much they cost, and how fast teams can iterate. Until now, the developer tools and the infrastructure telemetry have lived in completely separate worlds. The CoreWeave acquisition changes that. W&B can now build products that connect application-level experiment tracking with cluster health, hardware telemetry, and compute orchestration — a surface area that's hard to assemble without owning both the developer tools and the infrastructure. Reporting to the Director of Product Management, this Staff Product Manager will own the strategy and execution for the products at this intersection: W&B Launch (job submission and compute orchestration), infrastructure insights that leverage CoreWeave's unique telemetry and platform capabilities, and new product concepts — including agentic and automated research workflows — that only exist because W&B and CoreWeave are now one company. Sandboxes (managed development environments) are also part of this surface, but the core opportunity is building infrastructure-native developer tools that take advantage of the combined platform. You'll be working directly with frontier model builders — teams training on thousands of GPUs — to understand what they need and ship it. If you're energized by solving infrastructure challenges that directly accelerate deep learning workflows, collaborating with the world's best AI teams, and delivering tools that move the industry frontier forward, his role is for you. What You'll Do • Define and ship infrastructure-native products that only W&B + CoreWeave can build. This is the core of the role. The integration between W&B's experiment tracking and CoreWeave's infrastructure platform opens a new product surface — giving researchers visibility and control that spans their code, their runs, and the machines those runs execute on. You'll identify the highest-value opportunities in this design space, build conviction around them, and drive the roadmap from concept through launch and iteration., • Own W&B Launch and evolve it for the CoreWeave era. Launch is W&B's job submission and compute orchestration product. Today it helps teams submit training jobs to Kubernetes clusters and cloud providers. As part of a vertically integrated AI platform, Launch can go further — with deeper infrastructure awareness and the ability to serve as the orchestration layer for agentic and automated research workflows. You'll set the vision for what that looks like and ship it., • Spend real time with frontier AI teams and learn how they actually work. Foundation model builders are your primary customers. You'll spend significant time in their workflows — understanding how they manage infrastructure, debug failures, orchestrate computation, and increasingly automate their research processes. These conversations will directly shape the product roadmap., • Build the bridge between W&B product and CoreWeave platform engineering. This role sits at the seam between two organizations that are becoming one. You'll partner with CoreWeave's infrastructure and platform teams to identify integration opportunities, and with W&B's engineering teams to build them into products researchers actually want to use. Your ability to translate between infrastructure engineers and ML researchers will be critical., • Find and resolve friction points in the job submission, compute management, and infrastructure observability workflows, maintaining W&B's high bar for craft and quality., • Explore new product concepts at the hardware-software boundary. The design space opened by the CoreWeave integration is large — spanning profiling, environments, automation, agents, and more. You'll evaluate which new concepts have the highest impact for frontier AI teams and drive the most promising ones from zero to one. Who You Are • Experience: You have 7+ years as a product manager working on developer tools, deep learning infrastructure, or ML engineer platforms., • End-to-end ownership: You've taken a technical product—whether a model, orchestration feature, or developer tool—all the way to production, including defining success criteria, measuring effectiveness, and iterating to improve impact and user happiness., • Technical fluency: You're comfortable discussing Kubernetes and SLURM, job scheduling, hyperparameter optimization algorithms, and API design with engineers and AI researchers., • Cross-functional influence: You're skilled at managing and influencing AI engineers, software engineers, and stakeholders—with or without official authority—to align teams and drive outcomes., • Clear communication: A major part of this role is seeking feedback from many directions and channeling it into a single, executable stream. You bring clarity and organization to complex, fast-moving environments., • Care and taste: You have strong opinions about the products you use and a high bar for developer experience. Preferred • Experience with deep learning frameworks (PyTorch, JAX), distributed training, or LLM development workflows., • Hands-on experience with SLURM or Kubernetes for GPU-intensive workloads., • Prior exposure to W&B or other experiment-tracking and model management platforms., • Understanding of hyperparameter optimization methods and evaluation workflows for large models. Wondering if You're a Good Fit? We believe in investing in our people and value candidates who can bring their own diversified experiences to our teams—even if you aren't a 100% skill or experience match. Here are a few qualities we've found compatible with our team: • Outgoing and user-focused. You'll love this role if you enjoy connecting with real users day to day, helping them solve issues, and sharing patterns for making the most of our products, • Self-directed and willing to take risks. At our speed and scale, product managers need to proactively find solutions, improve processes, and collaborate with team members and engaged users. Your initiative will really shine here., • Hands-on with AI. You experiment with generative AI to improve your own workflow and build user-facing prototypes. You keep up to date every day with what's new in the AI / LLM world., • Passionate about developer experience. You care deeply about building tools that help AI practitioners accelerate their iteration and discovery. You know small friction points compound, and smoothing them out is what makes a delightful and winning developer tool. Why Us? We work hard, have fun, and move fast! We're in an exciting stage of hyper-growth that you will not want to miss out on. We're not afraid of a little chaos, and we're constantly learning.

Job Description Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster. We're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that — with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI. We're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services. If you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe. About This Role: We are seeking a Senior Backend Software Engineer to join the Core Backend team within Cloud Customer Experience (CCX). The CCX organization is at the forefront of delivering a best-in-class user experience for our AI-focused cloud platform, and Core Backend is the engine underneath it. Our mission is to provide an intuitive, seamless user flow while ensuring the backend reliability and scalability that set us apart from the competition. The Core Backend team owns the foundational services behind every interaction a customer has with Crusoe Cloud. Concretely, the team builds and operates: API Gateway: the front door to Crusoe Cloud. Every request to create, read, or manage a cloud resource flows through the gateway this team owns. That means request routing, authentication and authorization enforcement, rate limiting and throttling, API versioning, and the tracing that makes a single call debuggable end to end. Resource Management Layer: the abstraction between customer intent and physical infrastructure. Resource models and lifecycle state machines, reconciliation loops that drive declared state toward reality, capacity and placement coordination, and one consistent API surface behind every client. Quota Management: the system of record for what every organization and project is entitled to consume. Our team built and owns the quota model for all Crusoe products and its enforcement path, along with the request and approval workflows that gate GPU, compute, storage, and networking capacity - a low-latency, strongly consistent, correctness-critical service sitting directly in the path of every resource creation. Notifications: the platform-wide notification and eventing system that tells customers what is happening to their infrastructure - quota changes, capacity events, maintenance windows, billing thresholds, security alerts - across email, in-console, and webhook delivery. Event pipelines, templating, fan-out, delivery guarantees, deduplication, and per-user preference management at scale. User Onboarding Flows: the path from sign-up to first successful workload. Identity and organization provisioning, invitations and role assignment, verification checks, and the self-serve flows that let a new customer go from account creation to running GPUs without a human in the loop. Your work will focus on making these systems fast, reliable, and coherent - one gateway, one resource model, one entitlement story, one notification surface - as Crusoe Cloud's customer base and hardware footprint grow. What You’ll Be Working On: Design, develop, and maintain scalable and reliable services that power our cloud platform's user-facing experiences. Own and evolve the API gateway that fronts all Crusoe Cloud resource management traffic - routing, authentication and authorization enforcement, rate limiting, versioning, and tenant isolation - without becoming a bottleneck for the teams shipping behind it. Build the notification and eventing backbone that keeps customers informed about the state of their infrastructure, with delivery guarantees and preference controls they can trust. Evolve the quota and entitlement system into a first-class product surface: self-serve quota requests, transparent limits, and enforcement that is both fast and correct under contention. Reduce time-to-first-GPU for new customers by hardening and automating onboarding, provisioning, and identity flows. Extend the resource management layer so new infrastructure offerings can be modeled, exposed, and reconciled without bespoke one-off plumbing each time. Collaborate with cross-functional teams, like product and design, to evaluate tools, frameworks, and customer needs, creating innovative solutions that differentiate Crusoe Cloud. Contribute to architectural decisions that support reliability and maintainability across the company. Mentor engineers, enhance hiring practices, and contribute to building a strong, inclusive engineering culture. At Crusoe, we are redefining cloud infrastructure by integrating data center operations with seamless user experiences. From developing turn-key AI cloud infrastructure to managing advanced data center operations, Crusoe is at the forefront of innovation in AI-first cloud computing. Join us to help shape a platform that reduces carbon emissions while delivering best-in-class cloud services. What You’ll Bring to the Team: Customer-Centric Mindset: A passion for creating intuitive, high-quality solutions that directly impact customer success and satisfaction. Any experience building out infrastructure tooling is a plus. Professional Experience: 3+ years of software development experience, including programming with modern compiled languages such as Go, Rust, Java, or C++. Our services are primarily written in Go. API and Service Design: Experience designing versioned public APIs (gRPC/protobuf, REST) and the SDK, CLI, or Terraform provider surfaces built on top of them, with an eye toward backward compatibility. Gateway and Edge Concerns: A clear sense of what belongs at the API edge versus in a backing service - request routing, authn/authz enforcement, rate limiting and throttling, quota checks, input validation, and graceful degradation under load. Cloud Expertise: Proven ability to design and scale fault-tolerant distributed systems and develop managed cloud services. Data and State Management: Strong relational database skills (PostgreSQL), including schema design, transactions, isolation levels, locking, and safe online migrations for correctness-critical data such as quotas and entitlements. Event-Driven Systems: Practical experience with message queues and streaming systems (Kafka, NATS, Pub/Sub, or similar) and the patterns that make them reliable - at-least-once delivery, idempotent consumers, retries, backoff, and dead-letter handling. Directly relevant to notifications and resource lifecycle events. Asynchronous Workflows: Comfort building long-running, resumable workflows and reconciliation loops - state machines, control loops, or workflow engines such as Temporal - for provisioning, onboarding, and resource lifecycle management. Technical Proficiency: Strong fundamentals in data structures, algorithms, microservices, and infrastructure tools like Docker, Kubernetes, Terraform, and CI/CD systems. Observability and Reliability: Experience defining SLOs, instrumenting services with metrics, logs, and traces, and using that signal to debug production issues in systems you are on-call for. Collaboration Skills: Ability to work with cross-functional teams to align priorities and deliver customer-first solutions. Mentorship Abilities: Experience guiding engineers, improving hiring and onboarding processes, and driving team growth. Communication Skills: Exceptional ability to articulate complex ideas and align technical solutions with customer needs. Bonus Points: Direct experience building or scaling a public cloud console or developer platform. Familiarity with the unique requirements of AI/ML workloads and their impact on cloud resource management. Experience with financial or billing systems at scale (usage-based billing, credits, etc.). Prior experience in a high-growth startup environment or a "Neocloud" infrastructure provider. Contributions to open-source projects related to cloud-native infrastructure or developer experience. Benefits: Competitive compensation Restricted Stock Units Paid time off & paid holidays Comprehensive health, dental & vision insurance Employer contributions to HSA account Paid parental leave Paid life insurance, short-term and long-term disability Professional development & tuition reimbursement Mental health & wellness support Commuter benefits (parking & transit) Cell phone stipend 401(k) Retirement plan with company match up to 4% of salary Volunteer time off Compensation Range Compensation will be paid in the range of $170,000 - 205,000 + Bonus. Restricted Stock Units are included in all offers. Compensation to be determined by the applicants knowledge, education, and abilities, as well as internal equity and alignment with market data.

Job Description Runware is the AI inference platform that builds and runs its own infrastructure, end to end. Our Sonic Inference Engine has served more than 20 billion requests for over 1 million developers and 500 million end users, with 400,000+ models behind a single integration, at up to 10x lower cost per token than traditional providers. We are now building the AI Factory that runs it. The Sonic Inference Pod packs 1 MW of custom-designed compute into a 20-foot container with closed-loop, water-free cooling, sited wherever power exists. Pods are live in the US and Europe, and we are scaling to dozens of pods and tens of thousands of GPUs, all operated as one distributed fabric that reroutes traffic the moment a pod goes offline (announcement). Every one of those 400,000 models has to be on the right GPU, in the right pod, in seconds. Storage is what makes that possible. That is the job. The role As Senior Storage Engineer, you will own the storage architecture of Runware's AI supercomputer: how model weights, caches and customer data move from object storage on two continents to the NVMe and GPU memory of the node that needs them. You will design the data path, build the first version with your own hands, and set the standard for how storage is run across every pod. This is a hands-on senior individual-contributor role. You will specify the systems, benchmark them on real hardware, find the reason a 70 GB checkpoint took four minutes to load instead of twenty seconds, and then fix it at the root so it never happens again. You will work directly with our inference engine, platform and hardware teams, with our storage and NVMe vendors, and with the site teams deploying pods. Success means a cold model loads onto a GPU anywhere in the fleet in seconds, a new pod has its working set warm before it takes traffic, and a disk, node or whole site failing is invisible to the developer calling our API. What you'll do • Own the end-to-end storage architecture for the fleet: the durable object store that holds 400,000+ models, the per-pod high-throughput tier that feeds GPUs, the node-local NVMe cache, and the replication and placement logic that ties them together across the US and Europe., • Design and build the model distribution path. Decide how weights get from the source of truth to a pod, how they are chunked, deduplicated, prefetched and pinned, and how a new pod warms its working set before it takes production traffic., • Drive model load latency down and keep it down. Profile the full path from disk to GPU memory, including the kernel, file system, NVMe-oF or RDMA transport, GPUDirect Storage and the inference engine's loader, and remove the bottleneck wherever it sits., • Select, benchmark and operate the storage systems themselves: parallel and distributed file systems, object storage, NVMe drives and enclosures, and the software that manages them. Validate every choice on our hardware before it ships to a pod., • Set and hit reliability and durability targets. Own capacity planning, monitoring, alerting, drive health and failure prediction, rebuild behaviour, backup and recovery, and on-call for the storage layer., • Make storage a routine part of pod bring-up: a documented, automated playbook so that the storage tier of the next 1 MW pod is provisioned, validated and warm in hours, not weeks., • Partner with inference engine, platform and hardware engineering so that what we design is operable at scale, and feed what you learn from production back into the next generation of servers and pods., • Use AI to accelerate the work: automate benchmarks, runbooks, triage and tooling with LLM-based agents, so that a very small team can run storage for a very large fleet., • Own data residency and the operational side of storage security: encryption at rest, access control, retention and in-country placement for sovereign deployments. Requirements What we're looking for • 8+ years in storage or systems engineering, with several of those designing and running storage at a company that operates its own hardware at scale., • A track record of building storage systems, not just operating what someone else built. You have taken a design from a whiteboard to petabytes in production and know what goes wrong between the two., • Deep, current, hands-on Linux storage expertise: the block layer, io_uring and NVMe queues, file systems such as XFS, ext4 and ZFS, the page cache, and the tools to see exactly where an I/O spends its time., • Real experience with at least one parallel or distributed file system in production (Lustre, WEKA, VAST, GPFS, Ceph or similar) and with S3-compatible object storage at petabyte scale., • Strong understanding of NVMe, NVMe-oF, RDMA transports and the networking that storage rides on. You can tell a saturated PCIe link from a slow drive from a misconfigured switch., • Fluent in a systems language (Go, Rust or C/C++) and Python, and comfortable writing the tooling, benchmarks and automation yourself rather than waiting for someone else to., • You use AI to accelerate your own output every day, for scripting, benchmarking, analysis, documentation and debugging, and you have a clear view of how a small team armed with these tools should operate differently., • Comfortable owning outcomes in a fast-moving, ambiguous environment, making decisions with incomplete information and being accountable for latency, durability and cost., • Able to travel to sites in the US and Europe as needed.Nice to have, • Experience feeding large GPU fleets for AI training or inference: GPUDirect Storage, NCCL-aware data loading, model weight caching and the loaders in vLLM, SGLang, TensorRT-LLM or similar engines., • Hands-on experience with InfiniBand or RoCE fabrics and 400G+ Ethernet from the storage side., • Experience with content-addressed or deduplicated storage, erasure coding, and multi-region replication and consistency trade-offs., • Kernel or driver contributions, or deep familiarity with SPDK, DPDK or user-space storage stacks., • Experience with Kubernetes CSI, Ceph or Rook on bare metal, and an automation stack such as Ansible and Terraform with Prometheus and Grafana observability., • Familiarity with the storage hardware supply chain: drive qualification, firmware lifecycle, enclosure and backplane design, spares and RMA economics., • Experience building or running storage to meet data residency, sovereignty or compliance requirements across jurisdictions. Benefits What we offer • A rare mandate: design the storage layer of an AI supercomputer from the ground up, at a company whose business depends on doing it better than anyone else, with the hardware budget and backing to match., • Meaningful stock options., • We're a remote-first collective, meeting in person twice a year to plan, brainstorm and celebrate wins. We keep core hours for collaboration and calls; outside those, you set your own schedule., • Our release cycles are fast and intense, and they're followed by real downtime. We expect you to take it., • Generous paid time off, including vacation, sick days and public holidays., • Paid maternity, paternity and caregiver leave., • Twice-yearly company retreats in inspiring locations.

Job Description CoreWeave is The Essential Cloud for AI™. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence. Trusted by leading AI labs, startups, and global enterprises, CoreWeave combines superior infrastructure performance with deep technical expertise to accelerate breakthroughs and turn compute into capability. Founded in 2017, CoreWeave became a publicly traded company (Nasdaq: CRWV) in March 2025. Learn more at www.coreweave.com. What You'll Do: IT Engineering at CoreWeave designs, builds, and operates the systems that enable our employees and acquired organizations to work securely and efficiently at scale. The team partners closely with Security, Business Development, PeopleOps, and Corporate functions to deliver resilient, standardized, and automation-first IT solutions that support CoreWeave's rapid growth. About the role: CoreWeave is hiring a Senior AI Platform Engineer to own the design, implementation, and governance of AI across CoreWeave's employee environment. You'll be the technical owner for the AI tools our employees use every day, on every surface they ship on: chat assistants, desktop apps, coding agents, AI terminals, AI browsers, workplace knowledge tools, and whatever comes next. You'll make them safe to adopt by building CoreWeave's guardrails directly into the platform through identity, device, and tenant-level controls rather than policy documents alone. This role is for someone who is genuinely passionate about AI and lives on its bleeding edge: someone who is already tuning agent behavior every week, has run swarms of agents and agent loops rather than just chatted with a model, and wants to keep learning at the velocity this field now moves. The tools, models, and best practices in this job will change monthly. That should excite you, not exhaust you. This is not a traditional AI/ML engineering role, and it is not a traditional IT administration role. It is deliberately a composite role that combines three things: production software and SRE engineering, hands-on LLM and agent work, and enterprise IT controls across identity, devices, and SaaS. We expect strong candidates to arrive deep in two of the three and grow into the third. Tell us which two. What success looks like in the first year: CoreWeave employees get frontier AI capabilities before almost any enterprise on earth. When a vendor ships a new model, agent surface, or feature, you already know it's coming; you're plugged into vendor roadmaps, betas, and the community and you have an evaluated, governed rollout ready in days, not quarters. That speed is possible because of the foundation you build in year one: sanctioned tools governed through identity, a connector and MCP allowlist in production, an intake process so "is this allowed" has an answer, internal agents shipping through an IT-owned gateway, and leadership visibility into usage, cost, and risk. The foundation is the floor; the pace is the job. AI platform lifecycle and governance • Own the end-to-end lifecycle of employee-facing AI platforms across every surface they ship on (web, desktop, mobile, IDE, terminal, and browser): evaluation, procurement support, tenant design, rollout, configuration management, and ongoing operations., • Keep the Platforms in Scope list current as the market moves., • Establish CoreWeave's AI operating framework for IT: intake and review for new AI tools and agents, standards for internal bots, runbooks, a clear path from pilot to supported service, and enablement content that helps employees use AI tools well and safely. Guardrails as enforceable controls • Design and implement AI guardrails as enforceable controls, in partnership with Enterprise Security and IT Identity and Access: SSO and SCIM provisioning, role- and group-based feature entitlement, data-retention and training opt-out settings, browser-extension and desktop-app policy, and device-trust requirements for access., • Build and operate connector and MCP allowlists with data-source scoping across Okta, Google Workspace, Slack, Atlassian, GitHub, ITSM, and HRIS., • Partner with Enterprise Security, Legal, and Privacy to translate acceptable-use, data-classification, and regulatory requirements into technical policy, and support audits with the evidence those controls produce. Infrastructure you'll own • The IT-owned control layer for CoreWeave's internal chatbots and agents: the gateway, identity, secrets, MCP allowlisting, logging, rate limiting, and cost attribution in front of the serving stack, deployed on CoreWeave infrastructure alongside the teams that run it., • Inference endpoints, agent hosts, and developer AI tooling on managed devices, treated as managed endpoints with a lifecycle, configuration baselines, and observability., • The IT-owned share of CoreWeave's internal MCP servers, reusable agent skills, and shared agent configuration (system prompts, AGENTS.md and CLAUDE.md instruction files, tool policies), plus the identity, logging, and allowlisting standards, with reference implementations, that agents and MCP servers built by other teams must meet. Operations, reliability, and telemetry • Hold the AI services you own to SRE standards: automation and infrastructure-as-code for everything repeatable, reliability targets, on-call, and incident response., • Instrument usage, cost, quality, and risk telemetry across AI platforms, and build the dashboards and alerting that show leadership what is being used, by whom, and at what spend., • Serve as the senior escalation point for AI tooling issues., • Communicate clearly and proactively with executives, cross-functional partners, and employees. Who You Are: • 6+ years in software engineering, site reliability engineering, or IT systems engineering where you built and ran things in code, not just configured them., • 2+ years of hands-on experience building with or administering LLM-based products: API integration, prompt and tool design, retrieval pipelines, agent frameworks, multi-agent workflows and agent loops, or enterprise administration of tools such as Claude, ChatGPT Enterprise, Copilot, Gemini, Glean, or Rovo. You have shipped or run something with these, not just used them., • Strong software engineering skills in Python, Go, Rust, or TypeScript: you have built services and integrations that other people depended on and kept them running., • Experience operating services in production (containers, infrastructure-as-code, CI/CD, secrets management, and observability), or you have automated enterprise systems with code (Terraform for Okta or Google Workspace, CI/CD for device and SaaS configuration, API integrations a company depended on) and are ready to go deeper on containers and observability., • A working understanding of how enterprise IT control systems function, even if you have not administered them yourself:, • Identity and access: how SSO, SCIM, SAML/OIDC, and OAuth grant, scope, and revoke access, and what Conditional Access, Device Trust, and Zero Trust mean in practice., • Endpoint and device management: how MDM and device-trust tooling enforce policy on a managed laptop or browser., • SaaS administration: how permission and data-sharing models in tools like Google Workspace, Slack, Atlassian, and GitHub decide who can see what., • Proven ability to produce clear technical documentation and lead complex, cross-functional technical initiatives. Preferred: • Real-world experience administering one or more of these at enterprise scale: identity (Okta or Entra ID), endpoint management (Apple MDM/DDM, Jamf, Kandji, Munki, Intune, Chrome Enterprise), or SaaS platforms (Google Workspace, Slack, Atlassian, GitHub)., • Experience deploying and governing enterprise AI tools across a 1,000+ person organization., • Hands-on experience building custom Model Context Protocol (MCP) servers and integrations, authoring reusable agent skills, and shaping agent behavior through system prompts and repository-level instruction files (AGENTS.md, CLAUDE.md, or equivalent)., • Working knowledge of data governance for AI: data classification, retention, training opt-out, DLP, and the audit and logging capabilities of the major AI vendors., • Experience self-hosting and serving models., • Familiarity with compliance frameworks such as SOC 2, ISO 27001, SOX, and GDPR, and with emerging AI governance standards such as NIST AI RMF and ISO/IEC 42001. Wondering if you're a good fit? You may be a great fit if you already run swarms of agents and agent loops for your own work; you've been the person who figured out how to say "yes, safely" to a new AI tool instead of "no"; you're curious about how an Okta policy or an MDM profile actually enforces a rule and you'd rather build the control than write the memo; you think endpoints are wherever work happens; and you love turning ambiguous governance requirements into concrete, automated, testable controls.

Job Description CoreWeave is The Essential Cloud for AI™. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools, and teams that enables innovators to build and scale AI with confidence. Trusted by leading AI labs, startups, and global enterprises, CoreWeave combines superior infrastructure performance with deep technical expertise to accelerate breakthroughs and turn compute into capability. Founded in 2017, CoreWeave became a publicly traded company (Nasdaq: CRWV) in March 2025. Learn more at www.coreweave.com. Weights & Biases at CoreWeave CoreWeave acquired Weights & Biases to create the most powerful end-to-end platform to develop, deploy, and iterate AI faster. CoreWeave operates a growing footprint of data centers covering every region of the US and across Europe, and was ranked as one of the TIME100 most influential companies of 2024. By bringing together CoreWeave's industry-leading cloud infrastructure with the best-in-class tools AI practitioners know and love from Weights & Biases, we're setting a new standard for how AI is built, trained, and scaled. The integration of our teams and technologies is accelerating our shared mission: to empower developers with the tools and infrastructure they need to push the boundaries of what AI can do. From experiment tracking and model optimization to high-performance training clusters, agent building, and inference at scale, we're combining forces to serve the full AI lifecycle — all in one seamless platform. Weights & Biases has long been trusted by over 1,500 organizations — including AstraZeneca, Canva, Cohere, OpenAI, Meta, Snowflake, Square, Toyota, and Wayve — to build better models, AI agents and applications. Now, as part of CoreWeave, that impact is amplified across a broader ecosystem of AI innovators, researchers, and enterprises. As we unite under one vision, we're looking for bold thinkers and agile builders who are excited to shape the future of AI alongside us. If you're passionate about solving complex problems at the intersection of software, hardware, and AI, there's never been a more exciting time to join our team. What You'll Do You'll join the ML Workflows organization as the Engineering Manager for Artifacts & Registry, leading a team of six engineers. Registry is the organization-level source of truth for what a company has approved for production. It provides access control, protected aliases, lineage, and automation hooks, and it is where a model version goes once it moves out of research. Pinterest, Capital One, Canva, Recursion, and Dropbox all run on it, and for some of them it sits inside a production serving path. Artifacts is the layer underneath it: content-addressable storage, deduplication, lineage, and retention for datasets, model weights, checkpoints, and evaluation outputs, across S3, GCS, Azure, and CoreWeave AI Object Storage. Every object logged to W&B is an artifact. The team's mandate is also weighted heavily toward closing the gap between CoreWeave's infrastructure and the ML experimentation that happens in W&B. That includes extending the Registry beyond a record of decisions, so that promoting a model version can put it into serving on CoreWeave compute with lineage and access control carried through, and bringing compute and experimentation into a single unified experience rather than separate tools. This work is done in partnership with foundational infrastructure teams at CoreWeave and product teams across the W&B ecosystem. The current scope is well defined and load bearing, with enterprise customers relying on it daily. What is open is what comes next, where there is significant room for new products, new roadmaps, and deeper integration between CoreWeave and W&B. The role therefore calls for a product-first mindset alongside strong operational ownership. About the role You'll own the full lifecycle, from roadmap shaping through delivery and production reliability. You'll partner with product management on prioritization, unblock your engineers across team boundaries, and hold the reliability bar while the team ships new capability. The failure modes here are customer data and customer uptime, so operational judgment matters as much as delivery. You need to be technically fluent enough for the real architecture conversations: relational data modeling and query performance at scale, object storage, an analytical search index maintained alongside a transactional system of record, permission models, and the lifecycle of data customers cannot afford to lose. You're not afraid to get your hands dirty when the team needs it. Your primary focus is growing your engineers into autonomous leaders and technical decision-makers. We're an AI-forward organization and we expect you to champion that. This team already does, both in how they build and in what they build, including the agent-facing surfaces of the product itself. Like any role at a hyperscaler, this comes with high accountability and ownership. You'll own your team's outcomes end to end, make hard prioritization calls, and build a team that operates with autonomy and urgency. Who You Are • 3+ years of engineering management experience shipping platform, data, or infrastructure products, • 5+ years of software engineering experience prior to management, with backend systems depth, • Technical fluency in Go (or a comparable statically typed backend language), relational data modeling, and distributed backend systems. You won't write code daily, but you need to review PRs, unblock architectural decisions, and understand production incidents, • Experience managing teams that own production systems where the durability and correctness of customer data is the primary constraint, • Demonstrated ability to balance product delivery with technical health, covering technical debt, reliability, and on-call, • Experience partnering with product managers to shape a roadmap, including making the case for platform investment with evidence, • Track record of growing engineers across levels, from mid-level through senior, • Strong communication skills with both engineering and non-engineering stakeholders, • Comfortable operating in ambiguity, including product areas where the right level of investment is an open question you're expected to help answerPreferred, • Experience with ML infrastructure, ML platforms, model registries, or developer tools for data scientists, • Background in large-scale object storage, content-addressable storage, deduplication, or garbage collection over large object graphs, • Depth in query performance and schema migrations against large production databases, and experience with a columnar or OLAP store such as ClickHouse alongside a transactional system of record, • Familiarity with multi-tenant permission models, RBAC, and enterprise access control requirements, • Experience taking a mature, widely-adopted product into a new strategic phase rather than only building from zero, • Experience with post-acquisition platform integration, • Founding experience or early-stage background where you took a product from idea to the hands of usersWondering if you're a good fit? We believe in investing in our people, and value candidates who can bring their own diversified experiences to our teams, even if you aren't a 100% skill or experience match. Here are a few qualities we've found compatible with our team. If some of this describes you, we'd love to talk. • You're interested in owning a system other products depend on, and in extending it rather than only keeping it running., • You think reliability is part of the product, and you can make that case to product partners and leadership with data., • You care about developer experience and understand that infrastructure teams succeed when their users actually love the tools., • You've managed through organizational complexity before and you're comfortable navigating cross-team dependencies and shifting priorities.Why Us? We work hard, have fun, and move fast! We're in an exciting stage of hyper-growth that you will not want to miss out on. We're not afraid of a little chaos, and we're constantly learning. Our team cares deeply about how we build our product and how we work together, which is represented through our core values: • Be Curious at Your Core, • Act Like an Owner, • Empower Employees, • Deliver Best-in-Class Client Experiences, • Achieve More Together We support and encourage an entrepreneurial outlook and independent thinking.

Job Description Crusoe is on a mission to accelerate the abundance of energy and intelligence. As the only vertically integrated AI infrastructure company built from the ground up, we own and operate each layer of the stack — from electrons to tokens — to power the world's most ambitious AI workloads. When you join Crusoe, you join a team that is building the future, faster. We're in the midst of the greatest industrial revolution of our time. The demand for AI compute is boundless, and power is a bottleneck. We're solving that — with an energy-first approach that makes AI infrastructure better for the world and faster for the people innovating with AI. We're looking for problem-solving, opportunity-finding teammates with a sense of urgency, who believe in the scale of our ambition and thrive on a path not fully paved — people who want to grow their careers alongside a team of experts across energy, manufacturing, data center construction, and cloud services. If you want to do the most meaningful work of your career, help our customers and partners advance their AI strategies, and be part of a high-performing team that believes in each other, come build with us at Crusoe. Build the operating system for the AI datacenter Crusoe operates one of the world's largest managed GPU fleets, and it is growing fast. A fleet at this scale cannot be run the way GPU clouds have traditionally been run: runbooks, war rooms, and heroics. It has to be run by a unified platform that senses, reasons about, and acts on the entire fleet, so infrastructure that used to take a team to operate takes a service instead. That is what our cloud platform team builds. You will work on the control plane for one of the largest AI fleets in the world, at a point where fleet autonomy is still an open problem: nobody has fully solved this at this scale, in this market. A true platform, not internal tooling: We want to be explicit about that heading, because it is the thing most infrastructure roles get wrong. Everything we build ships as a product, fleet engineers, SREs, and product teams across Crusoe build their own services and workflows on top of what we ship. A platform team does not scale by doing everyone's work; it scales by making everyone's work self-serve. Concretely: API-first. Every capability is exposed through well-designed, versioned APIs behind a single gateway. If it isn't an API, it doesn't exist. No side doors, including for us. SDKs and paved paths. First-class client libraries, workflow templates, and golden paths so a fleet or SRE engineer can ship a new remediation or lifecycle workflow in days without asking the platform team. Micro frontends and a self-serve portal. Teams plug their own UI surfaces into one developer portal instead of building one-off dashboards. One console for the fleet, extensible by every team. Platform as product. Internal teams are customers. We own contracts, versioning, deprecation policy, quotas, documentation, and support. Adoption is our success metric: the platform wins when other teams choose it because it is the fastest path, not because it is mandated. What this platform is Four layers, built as one system: Agents on every site and host that collect telemetry and execute commands. A distributed infra graph: Models system connections down to the rack, fabric, power, and cooling layers. By integrating these connections with telemetry signals, the platform can precisely trace events to identify their blast radius and root cause. A reconciliation core: workflow engine, policy engine, and state reconciler that continuously close the gap between intended state and reality, exposed through the API gateway. Domain services: Services spanning provisioning, firmware upgrade, validation, deployment, repair and RMA, capacity, power and thermal, and Day-2 operations. Built once, run fleet-wide, consumable by any team through APIs and SDKs. We operate on a continuous autonomy loop—sense, correlate, reason, act, learn—incorporating guardrails that evolve from recommendation to full automation. We treat every recurring manual intervention as a signal to engineer the next automation. You'll thrive here if you Want to build a platform, not integrate one. This is core distributed-systems engineering: event buses, graph models, reconciliation loops, policy evaluation. Treat internal engineers as customers and sweat API ergonomics, docs, and onboarding the way product teams sweat UX. Like owning a hard abstraction and defending it as ten teams build on top of you. Believe the interesting problems are where physical infrastructure meets software: a firmware counter, a thermal event, and a scheduling decision are one problem, not three. Measure yourself by what stops paging humans, and by how fast another team ships on your platform. What you'll do Design and build core platform services: RBAC, tenancy, the workflow engine, policy engine, and state reconciler that drive fleet actions safely at scale. Design the public face of the platform: the API gateway, resource model, and versioned API contracts that fleet, SRE, and product teams build against. Build SDKs, workflow templates, and golden paths that make the platform self-serve, plus the developer portal and micro frontend framework that let teams bring their own UI surfaces. Build the inventory and topology graph as the fleet's source of intended truth, and the pipelines that keep it honest against reality (metadata drift is one of our top verified incident root causes; you will kill it). Build site, GPU, and network agents and the event bus that moves fleet telemetry and commands reliably. Deliver the platform roadmap: pilot site on the foundation layer, first site deployed entirely through the platform, zero-downtime firmware upgrades, first fully automated RMA, then 100K+ GPUs on platform with MTTD under 60 seconds and MTTR under 30 minutes. Work with embedded engineers from fleet and production engineering who bring the operational scar tissue, and turn it into services other teams extend. Requirements 10+ years building distributed systems, control planes, or infrastructure platforms. Strong software engineering skills in Go, Python, or Rust. Experience building platforms other engineers consume: public or internal APIs, SDKs, or developer tooling with real adoption. Depth in at least one of: workflow/orchestration engines (Temporal or similar), event-driven architectures, graph data models, policy/rules engines, or reconciliation-based control loops (Kubernetes operator patterns). Experience running what you build: you have carried a pager for a platform other teams depend on. Systems thinking across the hardware/software boundary. Bachelor’s degree in Computer Science, Data Science, or a closely related technical field. Bonus experience Internal developer platforms: API gateways, service catalogs, Backstage-style portals, micro frontend architectures. GPU or bare-metal fleet infrastructure: DCGM, Redfish/IPMI, firmware lifecycle. High-cardinality observability platforms (per-GPU telemetry at fleet scale). InfiniBand or RoCE fabrics. AI agents applied to infrastructure triage and autonomous remediation. About CAPE Vision. Crusoe's infrastructure runs as a self-aware, self-healing system: anticipating and auto-remediating failures, shaping its own power demand, and tuning silicon-to-orchestration as one instrument. The world's most reliable, efficient, and sustainable AI compute platform. Mission. We design, build, and operate the world's most reliable and energy-efficient AI infrastructure platform by treating the physical and digital layers as one software-defined system. Every day, for every workload, we automate away the latency, waste, and fragility between stranded energy and delivered intelligence. Benefits: Competitive compensation and equity packages Restricted Stock Units Paid time off, paid holidays & leave of absence programs Comprehensive health, dental & vision insurance Employer contributions to HSA account Paid parental leave Paid life insurance, short-term and long-term disability Professional development & tuition reimbursement Mental health & wellness support Commuter benefits (parking & transit) Cell phone stipend 401(k) Retirement plan with company match up to 4% of salary Volunteer time off Global travel insurance & emergency assistance Daily meals allowance Additional perks & programs specific to location Compensation Range Compensation will be paid in the range of up to $250,000 - $300,000 + Bonus.
