About the role

  • Ro is building a team focused on shipping LLM-powered products across the patient experience, clinical operations, and internal tooling.
  • We're hiring a Senior AI Engineer to join a new team we're building from the ground up alongside a Senior AI Lead and an Engineering Manager.
  • You'll own AI features from prototype through production and spend as much time improving workflows with clinical operators as writing code.

Responsibilities

  • Design, build, and ship production LLM powered features end-to-end.
  • Build the AI application layer, including prompt orchestration, tool calling, retrieval (RAG), embeddings, agent workflows, and structured outputs.
  • Develop evaluation infrastructure, including regression suites, LLM-as-a-judge evaluations, synthetic datasets, human review workflows, and quality metrics that catch regressions before users do.
  • Design observability systems that measure accuracy, latency, cost, hallucination rates, and model behavior in production.
  • Build safety and reliability guardrails that ensure AI systems meet quality, compliance, and operational requirements.
  • and make pragmatic build-versus-buy decisions.
  • Raise engineering standards across the team through technical leadership, code reviews, mentorship, and thoughtful system design.
  • 5+ years building production software, with at least 1-2 years building and deploying LLM-powered applications in production (or equivalent depth through substantial side projects or open-source work).
  • Strong Python engineer with experience building backend services and integrating modern AI APIs and frameworks.
  • We're building a new system.

Nice to have

  • These considerations may cause your compensation to vary.

Compensation
