Member of Technical Staff, Reinforcement Learning

About Baseline

Open source revolutionised how we write software, but its impact on robotics stays limited due to expensive hardware accessible only to well-funded labs. We run that hardware as shared infrastructure for the broader community, billed only for active compute. For a given task, policies are evaluated under similar conditions, giving researchers common ground for fair comparisons.

In this role you will

• Run post-training and reinforcement-learning loops for on-robot policy improvement.
• Design reward models from vision, language, and operator feedback.
• Implement on-robot safety constraints to halt or recover a trial before hardware damage.
• Post-train a reference policy and account for the measured change in success rate.
• Reconcile imagined or simulated rollouts with hardware outcomes when transfer is poor.

What we hope you'll bring

• Experience training reinforcement-learning systems in robotics, simulation, games, or agents.
• Knowledge of policy optimisation and offline or off-policy reinforcement learning.
• Publications in top machine learning or robotics venues, or equivalent experience.
• Fluency in Python and PyTorch, and the ability to debug a learning system end-to-end.
• Experience with JAX or Rust.
• Experience with GPU-accelerated simulation tools (Isaac Lab, Newton, mjlab, Genesis).

We encourage you to apply even if you do not believe you meet every qualification.
