- Exposure to Reinforcement Learning (RL) or Reinforcement Learning from Human Feedback (RLHF)
- Experience building automated evaluation pipelines
- Familiarity with agentic AI systems, AI assistants, or autonomous agents
- Research experience, publications, or contributions to ML/AI projects
- Delivering reliable benchmark and evaluation frameworks
- Identifying actionable model failure trends and root causes
- Providing data-driven recommendations that improve model quality
- Building scalable evaluation processes that accelerate research and development efforts
- Collaborating effectively across research, engineering, and product teams
- Hybrid work arrangement based in Menlo Park, California
- Collaborative team spanning multiple locations
- Fast-paced research and engineering environment with evolving priorities
