Job Description WHY WE EXIST Money should move as easily as data. It doesn't today. Technology is finally catching up to the need — customers expect instant, global, programmable money. HIFI exists to fix that. Our mission is to make money programmable by default, and to give developers and businesses the tools to move value at software speed. We're rebuilding the financial plumbing of the internet from the ground up. THE ROLE As a Senior Backend Engineer at HIFI, you'll own critical components of our payments infrastructure — from API design and data modeling to event-driven pipelines and financial-grade reliability. You'll work across the full lifecycle of modern money movement: account creation, fiat and stablecoin settlement, global payouts, and onchain connectivity. This is not a maintenance role. You'll solve hard, novel problems at the edge of what's possible in financial infrastructure, move fast, own your systems end-to-end, and directly shape how billions of dollars flow through the internet. If you touch it, you own it. That's how we work. WHAT YOU'LL BUILD * API Development: Design, implement, and optimize APIs that connect businesses to HIFI’s financial infrastructure platform, with a focus on performance, reliability, and developer experience. * Core Infrastructure: Build and scale backend systems that process transactions, ensure correctness, and provide strong guarantees around scalability, reliability, and fault tolerance. * System Performance: Continuously improve throughput, efficiency, and resilience across distributed services. * Collaboration: Work closely with product, compliance, and business teams to deliver end-to-end solutions. * Ownership: Participate in technical roadmap planning and carry projects from design through production. * User Focus: Engage with customers to understand their needs and translate them into effective solutions. WHAT WE'RE LOOKING FOR * Bachelor’s degree in Computer Science, Engineering, Math, or related STEM field, or equivalent practical experience. * 2+ years of professional software development experience. * Proficiency in one or more programming languages (JavaScript/TypeScript with Node.js, Go, Python, etc.). * Experience working with RESTful APIs. * Experience with PostgreSQL or other relational databases. * Familiarity with cloud platforms (AWS, Azure, or GCP) and containerization technologies (Docker, Kubernetes). * Working knowledge of version control (Git), CI/CD pipelines, testing, and monitoring/observability tools. * Strong communication and collaboration skills with both technical and non-technical teams. NICE TO HAVE * Knowledge of query optimization and database performance tuning. * Familiarity with concurrency control, distributed systems, and database transactions. * Experience working on distributed systems and optimizing them for scalability and performance. * Familiarity with event-driven architectures and messaging patterns (e.g., pub/sub, queues, streaming). * Exposure to job queues, caching services, and data pipelines. * Understanding of security best practices and a commitment to correctness in financial systems. * Experience building and launching a product from zero to one. * Background or interest in financial systems, payments, or blockchain/crypto technologies is a plus. THE HIFI CODE This is how we operate. Not aspirational — actual. Ownership If you touch it, you own it. Speed We bias toward motion. Clarity Confusion is a signal to act. Standards Quality matters always. Truth We value directness without drama. COMPENSATION & BENEFITS The expected salary range for this role is $135,000 - $160,000 USD. However, the starting base pay will depend on a number of factors including the candidate’s location, skills, experience, market demands, and internal pay parity. Depending on the position offered, equity and other forms of compensation may be provided as part of a total compensation package. We offer full health coverage (medical, dental and vision) and unlimited PTO. We're changing how modern business moves value. If that sounds like the problem you want to spend the next chapter of your career on, we'd love to meet you. EQUAL OPPORTUNITY STATEMENT HIFI is an equal opportunity employer. We do not discriminate on the basis of race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, veteran status, or any other legally protected status. We also provide reasonable accommodations during the hiring process. By submitting your application, you acknowledge that HiFi will process your personal information in accordance with our Applicant Privacy Policy. Compensation Range: $135K - $160K

You build infrastructure with users in mind — whether they're engineers, data scientists, our Care Team, or our members — prioritizing reliability and security. Pragmatism. You are driven by problems, not solutions. You prioritize solving the most important problems in the simplest way possible. Comfort with ambiguity. You have a proven track record of success in scaling businesses, fast-paced environments, and startups. You understand that rapid changes to the business, strategy, organization, and priorities are par for the course. OUR VALUES At Thyme Care, our core values guide us in everything we do: Act with our members in mind, Move with purpose, and Seek diverse perspectives. They anchor our business decisions, including how we grow, the products we make, and the paths we choose—or don't choose. Our salary ranges are based on paying competitively for our size and industry, and are one part of the total compensation package that also includes equity, benefits, and other opportunities at Thyme Care. Individual pay decisions are based on several factors, including qualifications, experience level, skillset, and balancing internal equity relative to other Thyme Care employees. The base salary for this role is $175,500-$195,000. The salary range could be lower or higher than this if the role is hired at another level. We recognize a history of inequality in healthcare. We're here to challenge the status quo and create a culture of inclusion through the care we give and the company we build. We embrace and celebrate a diversity of perspectives in reflection of our members and the members we serve. We are an equal-opportunity employer.

Job DescriptionCoreWeave 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 You'll Do: A lab signs with CoreWeave. They have thousands of GPUs waiting. Their first month? Spent on cluster setup instead of research. Building deployment scripts, fighting container images, wiring up job orchestration. They came to train models. Instead, they're doing operations. This is the problem. We're building the Applied Training team to fix it. You'll be an early member of a small team, responsible for our Kubernetes-native research cluster platform, or the sandbox client for agentic training and evaluation, or possibly a new project altogether. The goal is specific: Give every CoreWeave customer the research infrastructure that currently only exists inside frontier labs. About the role: • Contribute to the roadmap for Applied Training. Figure out what actually unlocks new workloads and what's just nice to have. Work directly and closely with customers, and other teams inside of CoreWeave that are building cloud native primitives. Compute, storage, networking, etc., • For the research cluster platform: design and build a complete research cluster experience. CLI, job configuration schema, Kubernetes operators, daemons. Solve the problems researchers actually hit: code distribution, checkpoint-triggered evaluation, cross-cluster scheduling, programmatic job control. Replace the patchwork of scripts customers keep building on their own., • For sandbox infrastructure: own the Python SDK and work in a very tight loop with the backend team. When an RL training run needs to spawn thousands of isolated containers for agent rollouts, that's this system. When someone wants to run agent benchmarks at scale, that's this system. Make it work with our Kubernetes clusters, storage, and auth so researchers don't have to think about infrastructure., • Write the documentation for running popular OSS training frameworks on CoreWeave. The work that can unblock customers and help them succeed., • Work with infrastructure teams and customers directly. The customers are large AI labs running thousands of GPUs. Understand how they structure their internal supercomputing stacks. Bring that knowledge back to what we build.Who You Are:, • 8-12+ years building distributed systems, ML infrastructure, or developer platforms., • Real Kubernetes experience: custom controllers, operators, scheduling, CRDs, workload orchestration at scale. Not just deploying things to Kubernetes or cluster administration., • Excited about rigorous engineering, but enabled by AI based workflows., • You understand what makes researchers productive. Code distribution matters. Fast iteration cycles matter. Workflows that don't require becoming infrastructure experts matter., • Familiarity with training: how distributed jobs get scheduled, how ranks initialize, what breaks at scale., • You've shipped infrastructure that other people rely on daily. Not prototypes. Production systems., • Experience building internal ML platforms or research clusters at a company doing large-scale training., • Familiarity with agentic AI: RL training with rollouts, agent evaluation, sandbox isolation for running untrusted code., • Background with Slurm, Ray, or similar workload orchestration. Opinions on where they fall short., • Experience with container runtimes, isolation (gVisor, Kata), or serverless platforms., • Be Curious at Your Core, • Act Like an Owner, • Empower Employees, • Deliver Best-in-Class Client Experiences The base salary range for this role is $165,000 to $242,000.

You are excited to personally fix issues, improve architecture, and stabilize systems before scaling them., • You know how to direct contractors and external engineers with precision, translating broad technical problems into clearly scoped execution tasks., • You are highly fluent in Python and AWS cloud-native architectures. Familiarity with React, TypeScript, and SQL is a plus., • You have strong judgment around what needs an immediate tactical fix versus what needs a deeper architectural rebuild., • You thrive in startup ambiguity, move fast, and don't need perfect documentation to figure out how things work., • Bonus points: experience in FinTech, KYC, fraud systems, onboarding workflows, workflow tooling, or real-time SaaS platforms.

Job Description About Us Applecart is the leading technology company that C-suites rely on to reach business-critical decision makers. The most important decisions are made by the hardest people to reach and influence. Historically, C-suite leaders have lacked the tools to reach the stakeholders who matter most to their business. The C-suites of hundreds of Fortune 500 companies, major agencies, trade associations, nonprofits, and governments use Applecart to put their best content in front of business-critical decision makers and those they trust — from policymakers and investors to CEOs, key employees, members of the media and more. Decision makers are informed by what they read, learn from advisors, hear from colleagues, and discuss with family and friends. To break through to them, you must reach them through the only channel that really moves them: those they know and trust.
