Create tooling to compare reward methodologies (preference models, rubrics, programmatic rewards) and quantify their impact on model behavior.
Build end-to-end pipelines from dataset preparation to evaluation and deployment, with monitoring and observability to surface issues.
Collaborate with scientists to translate research requirements into platform capabilities, balancing speed, reliability, and maintainability.
