Skills
About the Role
You will own ambiguous research problems from hypothesis through experimentation, building the training, evaluation, and data systems needed to test ideas and incorporate results into future models. You will advance reinforcement learning for longer-horizon coding tasks, train graders for non-verifiable rewards, improve training data quality, and work on real-time RL for coding agents.
Requirements
- Deep background in reinforcement learning
- Strong machine learning fundamentals
- Excellent programming and software engineering skills
- Ability to handle ambiguous research tasks with little guidance
- Data-quality expertise
Responsibilities
- Improve understanding of reinforcement learning for longer-horizon tasks and lower-compute training
- Train graders for coding tasks with non-verifiable rewards
- Improve the quality and difficulty of model-training datapoints
- Develop real-time reinforcement learning for coding agents
