RL Environment Software Engineer

Design and build high-quality RL environments that simulate real working environments end to end, developing agents for tasks within those environments until they are efficient and production-ready. Partner with the research team to scope which environments to build and why, staying ahead of future demand rather than only meeting present needs. Own the backend and infrastructure layers that make environments reliable and scalable while helping set engineering standards for a zero-to-one team as the RL function grows. This role sits at the intersection of research engineering and traditional software engineering, helping predict what high-quality environments the frontier will need next.
