Luma is building reinforcement learning systems at frontier scale in the UK, coupling policy optimization with thousands of inference workers and agentic environments. You will own the full RL loop across training, rollout, environments and rewards, pushing throughput and correctness as models scale.
Ideal candidates have hands-on post-training LLM RL experience, distributed PyTorch expertise, and a track record delivering scalable RL environments and evaluation harnesses for LLM agents.
