RL Engineer | Humanoid

Job description

Role: Reinforcement Learning Engineer – Manipulation Company: Humanoid Location: London, UK (King’s Cross) – on-site, five days a week Job Type: Full-time About Humanoid Humanoid is building the world’s most capable, commercially scalable and safe humanoid robots. Its platform, HMND-01, is already deployed in real industrial environments, which makes Humanoid the most serious humanoid robotics company in Europe. 300+ people, 34+ nationalities, flat structure: your decisions ship directly into real robots. Offices in London (HQ, King’s Cross), Boston, Vancouver and San Diego. Values: Speed, Ambition, Passion, Trust. About the role The VLA Core team builds the base vision-language-action model the whole company runs on, covering pre-training, world models and RL. In this role you use reinforcement learning, in simulation and on real hardware, to turn that model into high-performing, robust manipulation policies. This is a senior individual contributor role with no management track. Robotics experience is not required: very few people have done RL on real robots, so strong RL in any domain is what matters. The team is research-adjacent, but the output is policies that work on the robot. Results are shared as blog posts, not papers. What you are expected to do Train language- and vision-conditioned manipulation policies with RL, in simulation and in the real world. Build challenging and diverse suites of manipulation tasks in simulation. Work with Teleoperations to collect trajectories in simulation for behaviour cloning. Work with Testing and Operations to set up real-world RL training pipelines. Find ways to bring policies trained in simulation to the real world (sim-to-real). What you need to succeed 3+ years building deep learning systems in industry or research, with shipped models or published work to show for it. You have solved real problems with RL and deep neural networks, in any domain. You have trained models yourself (architecture, training and inference) on at least one of: LLMs, VLMs, image or video generative models. Agent building or LLM integration work alone is not enough. Strong Python and PyTorch or JAX. You can profile, debug numerics and write maintainable research code. Strong coding fundamentals. The process includes a LeetCode-style coding round, so come prepared. You are proactive: you can take an open, messy problem and drive it with…
