Senior Research Scientist, Model Evaluation

Senior Research Scientist, Model Evaluation

Who are we? Our mission is to scale intelligence to serve humanity. We’re training and deploying frontier models for developers and enterprises building AI systems that power content generation, semantic search, RAG, and agents. We believe our work is instrumental to the widespread adoption of AI and that each person on the team contributes to increasing the capabilities of our models and the value they bring to customers.

Evaluation is critical to making progress in scaling intelligence. As models become superhuman in many real-world use cases, we continue to develop new evaluation techniques that accurately reflect current capabilities and set the agenda for future progress. In this role you will create next‑generation evaluation methods and infrastructure to measure LLM progress.

• Create ambitious new evaluation benchmarks that push the limits of what our models can accomplish.
• Work cross‑functionally with teams to translate model feedback into trustworthy, repeatable evaluations.
• Conduct research to advance the state-of-the-art in LLM evaluation methods, including training LLM judges, refining LLM‑based data synthesis pipelines, and improving evaluation efficiency.
• Build scalable and reusable tools for digging into model performance.

• Rapidly build prototypes that demonstrate LLM boundaries and develop resources to measure those capabilities.
• Have spent significant time reviewing complex data and LLM outputs to ensure high data quality.
• Are obsessive about rigorously measuring AI capabilities and ensuring measurements align with desired outcomes.
• Have strong software engineering skills.

If some of the above doesn’t line up perfectly with your experience, we still encourage you to apply!
