THE ROLE We're looking for a highly skilled Senior Product Engineer who is excited about building in an AI native, agentic world. This is not a traditional frontend or backend role! It’s for engineers who: - use AI coding tools (Claude Code, Cursor, Copilot, etc.) as a force multiplier, - think in terms of systems, workflows, and agents, not just endpoints and screens, - can turn ambiguous product problems into working, production-ready solutions, - want to help evolve our platform toward an agent-driven future in healthcare. You’ll work closely with Product, Design, and other engineers to re-imagine how our systems are built, extended, and operated as AI becomes a first class part of the development process. WHAT YOU’LL DO Build AI Native Systems - Design, implement, and operate backend and fullstack systems that incorporate LLMs, tools, and agents as core components; - Build agentic workflows (multi-step, tool using, stateful systems) that solve real product and operational problems; - Integrate LLMs safely and reliably into production systems, with attention to observability, cost, and failure modes. Engineer with AI as a Partner - Use modern AI coding tools (e.g. Claude Code/Codex/Pi/Cursor) to accelerate development, refactoring, and exploration; - Set patterns and standards for how AI is used in day to day engineering work; - Help the team move faster without sacrificing quality or clarity. Product Driven Engineering - Collaborate closely with Product Management, Design, and other stakeholders to shape solutions, not just implement specs; - Translate high level goals into technical architecture and execution plans; - Contribute to roadmap discussions with a strong systems and platform perspective. Own the System End to End - Design APIs, services, and data models (primarily backend leaning); - Ensure reliability, security, privacy, and scalability in a regulated healthcare context; - Operate and observe the system’s behavior in the real world; - Improve developer experience and internal tooling where it unlocks leverage. WHAT YOU’LL NEED Required - 7+ years of experience as a Software Engineer, with strong knowledge of major parts of our tech stack (AWS, Java, Typescript) - Strong experience in building with LLMs in production, not just prototypes - Clear enthusiasm for the capabilities and opportunities of AI and agentic systems - Strong system design skills and comfort working in ambiguous problem spaces - Ability to communicate clearly with technical and non-technical stakeholders Strong Plus - Experience designing, building, and operating long running workflows, background jobs, or distributed systems - Familiarity with healthcare, regulated products, or safety critical systems - Startup or fast moving product environment experience What We Care About (Beyond the Resume) - You’re curious and opinionated about where software development is going - You ship and you iterate based on real world feedback - You don’t wait for perfect specs; you help create them! - You see AI as a new abstraction layer, not a gimmick WHAT YOU CAN EXPECT AT 9AMHEALTH At 9amHealth, you'll join the exciting environment of a startup with the stability of highly experienced founders that have successfully built a business from scratch.
