About this role

  • Own ML projects end-to-end: take problems from exploration through production deployment and keep iterating once real users are on them
  • Build agentic LLM systems: design multi-step workflows with tool use, retrieval, and orchestration, and make them reliable enough for clinical settings
  • Treat evaluation as core engineering work: build eval sets, offline and online harnesses, LLM-as-judge pipelines with human review, and regression tests that catch quality drops before they reach users
  • Improve model quality with whatever fits the problem: prompting, retrieval, distillation, or fine-tuning, chosen on evidence rather than habit
  • Work across the full AI stack: data prep, model adaptation, serving, monitoring, and the feedback loops that keep systems improving in production
  • Partner with Product, Clinical, and Engineering: translate clinical requirements into technical decisions and surface tradeoffs early
  • Help the team get better: review code, share what you learn, and mentor engineers earlier in their careers

Benefits

  • A stimulating, fast-paced environment with lots of room for creativity
  • A bright future at a promising high-tech startup company
  • The opportunity to work with a talented team and to add real value to an innovative solution with the potential to change the future of healthcare
  • A stimulating environment with room for creativity
  • A flexible environment where you can control your hours (remotely) with unlimited vacation
  • Access to our health and well-being program (digital therapist sessions)
  • Remote or Hybrid work policy
  • Career development and growth- Hands-on LLM work in production: prompting, retrieval, tool calling, and agent-style workflows
  • Clear communication with both technical and clinical stakeholders
  • Experience shipping ML systems to production that people actually depend on
  • Comfort with ambiguity: you’ve taken loosely defined problems and turned them into something running in production
  • Strong ML fundamentals: you know which approach fits which problem and can reason clearly about tradeoffs
  • A rigorous approach to evaluation: you’ve built eval datasets and frameworks, and you can tell a real improvement from noise
  • Solid engineering skills: production-quality code, familiarity with distributed systems, and the patience to debug messy ML pipelines
  • Experience with fine-tuning or preference optimization (RLHF, DPO, or similar)
  • Healthcare AI, or other high-stakes domains where errors carry real cost
  • Built agent frameworks or evaluation tooling from scratch
  • Open source contributions, technical writing, or other knowledge sharing
