Job Specifications

Humanoid is the first AI and robotics company in the UK, creating the world’s most advanced, reliable, commercially scalable, and safe humanoid robots. Our first humanoid robot HMND 01 is a next-gen labour automation unit, providing highly efficient services across various use cases, starting with industrial applications.

Our Mission

At Humanoid we strive to create the world’s leading, commercially scalable, safe, and advanced humanoid robots that seamlessly integrate into daily life and amplify human capacity.

What You’ll Do

Train language-vision conditioned manipulation policies via reinforcement learning (RL) in simulation and in the real world.
Construct challenging and diverse suites of manipulation tasks in simulation.
Partner with teleoperations to collect trajectories in simulation for behavior cloning.
Partner with testing and operations to establish real-world RL training pipelines.
Experiment with various ways of bringing policies trained in simulation to the real world..

We’re Looking For

3+ years building deep‑learning systems (industry or research) with shipped models or published artifacts to show for it.
Hands‑on with at least one of: LLMs, VLMs, or image/video generative models — architecture, training, and inference.
Experience solving real problems using reinforcement learning with deep neural networks in any domain.
Strong Python + PyTorch/JAX; you can profile, debug numerics, and write maintainable research code.
You are self-driven, pro-active, communicate efficiently, document experiments clearly and communicate trade‑offs crisply.

Nice to have

Experience with simulators for robotics (Isaac Sim, MuJoCo etc.)
Experience in RL for robotics.
Experience building infrastructure for large-scale RL (e.g. using ray).
Publications at ICLR/ICML/NeurIPS or equivalent open‑source contributions.
Familiarity with OpenVLA, Physical Intelligence (π) models, or similar open VLA frameworks.

What We Offer

Competitive salary plus participation in our Stock Option Plan
Paid vacation with adjustments based on your location to comply with local labor laws, and additional paid sick leave days
Travel opportunities to our Vancouver and Boston offices
Office perks: free breakfasts, lunches, snacks, and regular team events
