Responsibilities
- Design widely used APIs, frameworks, and abstractions with legible interfaces and principled defaults.
- Embed with research teams, build systems supporting their work, and transfer ownership to teams that will maintain them.
- Improve the reliability and structure of research codebases without slowing research progress.
- Prevent silent failures through type safety, invariants, targeted testing, and refactoring.
- Support the health of production RL systems through monitoring, regression detection, and triage tooling.
- Define engineering standards, review practices, and design patterns while mentoring researchers and engineers.
- Design RL environment abstractions, sandboxed agentic model-tool interfaces, dataset lifecycle systems, data-access layers, probes, and statically verifiable coding standards.
Requirements
- Deep expertise in Python, including static typing, safe asynchronous and concurrent programming patterns, and performant code.
- A track record of designing intuitive, safe APIs or frameworks adopted by other engineers or teams.
- Experience working productively in large, evolving, or research-oriented codebases that the candidate did not originally write.
- Ability to anticipate and structurally prevent failure modes, especially silent failures, through system design, type safety, and testing.
- Strong written and verbal communication skills and the ability to explain system designs to collaborators with varied engineering backgrounds.
- Ability to scope work from loosely defined problems and drive it to maintainable outcomes.
- Preferred qualifications include experience with ML research or reinforcement-learning infrastructure, agentic systems, LLM training pipelines, large-scale distributed systems, sandboxed or remote execution platforms, data processing, dataset lifecycle management, plugin systems, team embedding or consulting, code standards and lint rules, technical leadership, or open-source maintenance.
- A bachelor’s degree or an equivalent combination of education, training, and/or experience in a relevant field is required.
Benefits
- Hybrid policy requiring staff to work from an office at least 25% of the time, with some roles requiring more office time.
- Visa sponsorship is available, with immigration-lawyer support.
- Competitive compensation and benefits, optional equity donation matching, generous vacation and parental leave, flexible working hours, and office collaboration space.
