The Managed Platform Services team owns and operates multiple customer-facing products, with an active and growing roadmap. This is a full software engineering role — you'll ship customer-facing features, build systems from 0 to 1, and scale existing services alongside a team of strong generalist engineers. What sets you apart is your systems programming expertise, which you'll bring as a technical authority on our Edge & Agents domain: the software that runs directly on customer infrastructure. This agent code is mission-critical — a failure here is a customer production incident. You'll provide deeper technical oversight on existing, inflight, and planned edge systems while contributing broadly across the platform. This is a full-time position. What You'll Be Working On: * Customer-Facing Feature Development: Build and scale core platform services end-to-end — from greenfield 0-to-1 projects to scaling systems handling growing production traffic. * Edge & Agents Technical Oversight: Serve as the team's subject matter expert on edge software. Review existing agent architectures, provide technical guidance on inflight designs, and shape how we build and operate software at the system level. * Edge Agent Development: Build and maintain lightweight, high-reliability agents deployed on customer VMs. Minimize CPU/memory footprint without sacrificing observability coverage. * Linux Kernel Metrics & eBPF: Instrument low-level system metrics using eBPF and procfs to power Crusoe's monitoring and telemetry pipeline. * Packaging & Distribution: Own agent packaging and deployment via Helm charts, ensuring smooth delivery across customer environments. * Pull-Based Scraping Architecture: Design and evolve the "pull" scraping logic that collects metrics from customer infrastructure with minimal operational overhead. * Cross-Functional Collaboration: Partner with Control Plane, Storage, and SRE teams to ensure agent data feeds are reliable, well-structured, and operationally sound. * Cross-Team Bridge: Serve as the technical bridge between the Managed Platform Services team and adjacent infrastructure teams — including SRE and Compute — who work on the cloud hypervisor and lower-level platform layers. Build enough expertise in their domains to collaborate effectively, represent your team's requirements clearly, and influence decisions that affect the edge agent stack. * Technical Leadership: Set patterns and frameworks adopted across the team. Mentor senior engineers, contribute to architecture decisions, and help scope quarterly roadmap items with engineering and product leadership. What You'll Bring to the Team: * Systems Programming Expertise: Strong proficiency in Python, Go, and/or Shell scripting, with comfort working across languages as the problem demands. * Linux Kernel Metrics: Experience instrumenting low-level system metrics. Comfort working at the procfs level. * Kubernetes & Helm: Strong understanding of Kubernetes internals and experience packaging and deploying workloads via Helm charts. * Operational Mindset: On-call experience on a customer-facing team is required. You proactively identify gaps in monitoring, alerting, and tooling — and close them. * Systems Programming Expertise: Strong proficiency in Python, Go, and/or Shell scripting, with comfort working across languages as the problem demands. * Reliability-First Engineering: You design for crash safety, low resource footprint, and graceful degradation. You think about what happens when things go wrong before writing a line of code. * Scalable Design Thinking: You plan how systems evolve under traffic growth. You consider resiliency, HA, and disaster recovery from the start. * Staff-Level Impact: You lead cross-domain efforts, own team architecture, and coach multiple engineers across and beyond your team. You identify one-way door decisions, proactively drive solutions without being asked, and introduce frameworks that uplevel the group without requiring your direct involvement. You have a healthy bias to action — you bring solutions, not just problems. * Communication: Concise, proactive, and anticipates blockers. Keeps stakeholders informed without needing to be asked. 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 $210,000 - $255,000 + Bonus.

What You'll Do • Own the design and implementation of cloud-side autonomy pipelines that directly support and scale our onboard perception stack., • Leverage satellite imagery, aerial surveys, and structured data to build semantic and geometric world models of customer delivery zones., • Design and ship tools that predict deliverability, generate high-fidelity priors, and reduce the operational friction of onboarding new customers in new environments. You'll step in where our on-vehicle capabilities can't solve the problems we need to solve in order to scale the product., • Train and deploy mid- to large-scale models for semantic segmentation, 3D geometry, and learned preference modeling., • Design evaluation and validation infrastructure to ensure models behave reliably in the field., • Work across engineering to integrate your work into fleet-facing autonomy systems., • Lead architectural decisions, drive experimentation, and help the team push the limits of what's possible with production-grade perception at scale. What You'll Bring • At least 5+ years of experience building and deploying deep learning-based perception systems, particularly in 3D geometry, semantic understanding, or mapping from remote sensing data., • Strong understanding of classical computer vision (e.g. camera calibration, epipolar geometry, structure-from-motion) and the ability to blend it with modern ML approaches., • Hands-on experience training, iterating on, and optimizing CNN and transformer architectures in production environments., • An engineering mindset focused on outcomes over experimentation—you know how to prioritize what's good enough to ship now and what needs to be architected for scale later., • Familiarity with building training, data annotation, and evaluation pipelines—not just models., • Comfort working across systems: jumping into data pipelines, training infrastructure, or debugging distributed training issues as needed., • Experience deploying models in real-world, high-stakes robotics or autonomy applications is a strong plus. Why This Team? • You'll own real-world autonomy problems that matter—delivering essential goods around the world, in thousands of diverse backyards and environments., • You'll have autonomy and trust to define the roadmap and drive architectural decisions that shape Zipline's global operations., • You'll work on cutting-edge problems with people who care deeply about quality, systems thinking, and solving hard problems with elegance and clarity. A Few More Things Zipline is an equal opportunity employer and encourages candidates from historically underrepresented backgrounds to apply—even if you're not sure you're a perfect fit. If you care about shipping high-impact autonomy systems in production, we want to hear from you. What Else You Need to Know The starting cash range for this role is $180,000 - $265,000. Please note that this is a target, starting cash range for a candidate who meets the minimum qualifications for this role.

We're looking for a deeply technical software engineer to join the Autonomy Validation team — a core team responsible for building the infrastructure, tools, and frameworks that support software validation across the entire Autonomy organization. This includes planning, perception, control, and all of the decision-making logic that powers our self-flying aircraft. Our autonomy stack is highly custom-built, and while that gives us unmatched control and performance, it also means standard out-of-the-box testing tools don't work. In this role, you'll take ownership of developing robust internal platforms for validation — enabling both simulation at scale and rigorous scenario testing — so that autonomy engineers can ship with confidence. This is not a QA role. It's a foundational software engineering position building critical systems that will directly shape how we test, verify, and deploy autonomy safely around the world. What You'll Do • Build and own the infrastructure for validating autonomous features and system performance across planning, perception, and control., • Design and develop simulation tools and scenario generation for large-scale and high-fidelity testing of autonomy under real-world and edge-case conditions., • Develop custom tools for validation and testing of autonomy components that plug into our internal autonomy development stack., • Create scalable, reliable, and automated solutions for running, tracking, and analyzing thousands of validation tasks across autonomy org., • Collaborate deeply with:, • Autonomy engineers, to understand how system behavior should be evaluated., • Systems and data engineers, to ensure metrics, safety thresholds, and requirements are codified in test infrastructure., • Flight test and QA teams, to connect real-world results back into test tools and CI loops., • Establish best practices for software release validation, helping ensure our autonomy stack is safe, measurable, and production-ready., • Contribute to internal docs, standards, and validation workflows that scale across the autonomy organization. What You'll Bring • 3+ years of experience building systems for testing, simulation, or safety validation — ideally in autonomy, aerospace, robotics, or other real-time, safety-critical environments., • A strong software engineering foundation, including fluency in C++, Rust, C, or C#., • Experience with custom simulation tools, game engines, or scenario generation frameworks., • Familiarity with cloud infrastructure, containers, and distributed execution pipelines (e.g., Docker, Kubernetes, AWS). A track record of building tools or platforms used by other engineers — infrastructure that enables teams to move fast while maintaining safety and quality. What Else You Need to Know The starting cash range for this role is $170,000 - $200,000.

Job Description The Problem Severe mental illness affects over 15 million adults in the United States. Schizophrenia. Schizoaffective disorder. Bipolar I. Treatment-resistant depression. These are the conditions the rest of healthcare has systematically failed to build for. What makes this problem different from most of healthcare is that the tools to solve it do not exist. The clinical protocols, the measurement science, the precision medicine, the technology to deliver coordinated longitudinal outpatient care for this population. None of it has been built. This is a frontier problem, and it requires frontier science and care delivery to solve. We are developing all of it. The care, the science, the technology. Who We Are Amae Health is a Series B, venture-backed Public Benefit Corporation delivering specialty outpatient care for people with severe mental illness through high-acuity, in-person clinics nationwide. Our integrated model brings psychiatry, therapy, primary care, dietitians, and community support together under one roof. Leading health systems—including NewYork-Presbyterian, Cedars-Sinai, Mass General Brigham, Novant Health, and CommonSpirit—partner with us to expand this level of care. Alongside care delivery, we are building the science and technology the field has long lacked—proprietary clinical protocols, novel measurement, and an AI-driven data platform designed for severe mental illness. The impact: fewer hospitalizations, greater stability, and more people living meaningful lives in their communities. The Team We are clinicians, operators, technologists, and scientists who chose Amae because the problem is hard and the stakes are real. We are not interested in incremental improvements to a broken system—we are redefining it. Every function—finance, product, people, growth, technology—exists to serve one goal: better outcomes for the people we care for. The Role We are seeking a Senior/Staff Full-Stack Software Engineer to help build and scale Amae Health's patient and clinic-facing technology platform. In this hands-on individual contributor role based in San Francisco (in-person, full-time), your work will be central to shaping how patients and families access our precision psychiatry services. What You'll Work On • Design, develop, and ship full-stack web applications using Next.js, React, TypeScript, and Node.js, • Architect, implement, and maintain APIs and backend services that power our clinical and patient-facing experiences, • Deploy, monitor, and scale production systems using Vercel, AWS, or similar cloud infrastructure, • Integrate securely with healthcare data sources (EHRs, FHIR, HL7) in compliance with HIPAA and related regulations, • Collaborate closely with product, design, and clinical teams to turn real-world healthcare workflows into intuitive, performant software, • Write clean, testable, maintainable code and contribute to internal tooling, documentation, and developer experience, • Help shape Amae's long-term technical direction by mentoring teammates through code reviews and architectural discussions, • 5+ years of experience building and shipping full-stack web applications, • Deep proficiency in React, Next.js, TypeScript, and modern front-end tooling, • Strong backend experience in Node.js (Python a plus) and SQL/PostgreSQL, • Experience deploying and managing applications on Vercel, AWS, or equivalent cloud environments, • Familiarity with FHIR, HL7, and healthcare interoperability standards (nice-to-have), • Solid understanding of security, authentication/authorization, and data privacy best practices, • Comfortable in a fast-paced startup environment balancing rapid iteration with sound engineering discipline, • Degree in Computer Science, Engineering, or equivalent experience Most healthcare companies ask you to optimize an existing system. We're building one that has never existed. • A national care model designed for the highest-acuity patients in behavioral health., • Precision medicine for severe mental illness, using multimodal clinical, behavioral, and social data to personalize treatment., • A clinical operating system that integrates longitudinal data, real-time patient signals, and purpose-built tools into a single decision layer., • New science and measurement frameworks to define what real outcomes look like in SMI. Amae Health is committed to fair and equitable compensation practices. Base salary range for this role is $175,000 to $220,000 per year based on level and a full-time schedule; the compensation package will include equity. Total compensation includes comprehensive medical/dental/vision, unlimited PTO, parental leave, and programs built around employee well-being. We'll share specifics during the interview process. Amae Health is building the care platform, the precision medicine, and the frontier science that severe mental illness has never had. If you want to be part of creating something this hard and this important, something that has never been done, we'd like to talk. What We Value We center care in all we do. Empathy is not a brand value. It's how we make clinical decisions, build products, and treat each other. We challenge convention. The existing system is the problem. We question it, we test alternatives, and we move with urgency when something works. We take the work seriously, not ourselves. High standards and humanity are not in tension. We hold a hard bar for quality while leaving room for humor and levity. Your job isn't done until the job is done. We close gaps, we follow through, and we don't hide behind titles or org charts. We win together and fail together. We own outcomes as a team. We learn fast. We don't do blame. We hustle with humility. Speed matters. So does integrity. We assume best intent and stay grounded in the mission.
