Reinforcement Learning Researcher

Raydar
San Francisco, California, United States Posted Nov 11, 2026
Full-time

About this role

About the company

Our client is a technology company.

The role

Raydar is recruiting for this role on behalf of our client. Lead a research agenda in offline reinforcement learning, taking ideas from initial question through to shared findings. The position prizes scientific depth and judgment over engineering breadth, and pairs you with a more established colleague while leaving space to chart your own path.

What you'll do

  • Drive offline reinforcement learning research from start to finish, including choosing which questions to pursue and communicating the outcomes.

  • Raise the performance of learned control policies on internal evaluation suites and build on earlier policy work.

  • Train models on large, uneven-quality collections of data where feedback is scarce, applying several value estimation approaches.

  • Investigate model-based methods and learned environment models for continuous control.

  • Examine what keeps reinforcement learning training stable as data, compute and model scale increase.

  • Design rigorous experiments with dependable baselines and watch findings get tested on physical robots.

  • Requirements

  • What we're looking for

  • Background in reinforcement learning research, in a research or applied scientist capacity, connected to generative visual models.

  • A record of papers accepted at leading machine learning or robotics venues.

  • Depth in core and offline reinforcement learning topics, such as value estimation, goal-directed learning, policy design and training stability at scale.

  • Familiarity with model-based methods for continuous control or with multimodal value estimation.

  • An advanced degree (PhD or master's) in machine learning, computer science or an adjacent area, centered on reinforcement learning.

  • Ability to work on-site six days a week.

  • Bonus points

  • Prior exposure to visual generative models applied to robotics.

  • Time spent doing research at a top-tier AI organization.

  • Contributions to publicly shared reinforcement learning codebases.

  • Experience with large-scale simulation, sim-to-real transfer or robotics, including JAX.

  • Benefits

  • Compensation and benefits

  • Base salary: USD 200,000 to 350,000 per year

  • Equity

  • Health, dental and vision coverage

  • Location and work model

  • San Francisco, CA, United States

  • On-site, 6 days per week in office

  • Full-time
