About the role

You’ll build AI systems that can complete real work end to end. The work sits between applied research and production engineering: understanding model behavior, designing agent architectures, building evaluations, and building off of the latest research.

Responsibilities

  • Design and build long-horizon agents that plan, use tools, maintain state, recover from failure, and interact with data and source systems.
  • Build evaluations for agent decisions and end-to-end task performance.
  • Test and integrate frontier models across complex life sciences workflows.
  • Develop the tooling and infrastructure needed to create, debug, and improve agents quickly.
  • Build the tool chain to enable the delivery of agent systems in partnership with AI Strategy and product.
  • Own systems from early exploration through production operation, including reliability, observability, and ongoing improvement.
  • Share clear technical findings that help the team make better architecture and model decisions.

Qualifications

  • Research-grade engineers who ship: You can investigate a hard technical question rigorously, make a clear decision, and turn the result into production software.
  • Strong AI systems judgment: You understand that model quality depends on the surrounding system, including tools, context, state, evaluation, and human oversight.
  • Pragmatic problem solvers: You choose approaches based on evidence and tradeoffs, not ideology.
  • High agency: You can take an ambiguous goal, create structure, and move the work forward without waiting for a detailed specification.
  • Owners: You care about the quality, clarity, reliability, and long-term maintainability of what you build.
  • Clear collaborators: You communicate technical ideas simply and work well across engineering, AI Strategy, and product.
