## About the role

Build training environments. Define tasks, observations, actions, state transitions, rewards, and termination conditions. Create environments where agents ask questions, use tools, recover from errors, and reach verifiable outcomes. Design rewards and verifiers. Implement checks for task completion and intermediate progress. Find reward-hacking opportunities, ambiguous success criteria, and shortcuts that let agents pass without solving the task.

- Strong engineering skills and experience writing tested, maintainable software
- Experience defining task interfaces, managing environment state, implementing rewards, and debugging agent–environment interactions

- Clear technical communication and comfort taking an open-ended problem from an initial prototype to a reliable system
- Speech, audio, conversational agents, or full-duplex interaction
