Job Description:

We're looking for a highly skilled Senior Full Stack 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.

Job Responsibility:

  • 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
  • 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
  • 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
  • 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 behaviour in the real world
  • Improve developer experience and internal tooling where it unlocks leverage

Requirements:

  • 7+ years of experience as a Software Engineer
  • Strong knowledge of major parts of our tech stack (AWS, Java, Typescript, Python)
  • 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

Nice to have:

  • 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 offer:
  • Health, dental, and vision insurance
  • Flexible PTO
  • Work from home options
  • Professional development budget
  • Support continuing education
