RL Lead, Humanoid Robotics & Post-Training

Datamentors; Portugal; Presencial; EUR 90 000 - 130 000; Tempo integral

Resumo da oferta

Datamentors is building the next generation of autonomous robotics, combining AI, robotics, and VLA models. You will own the post-training stage of the Ardia humanoid platform, raising success rate and robustness through RL fine-tuning, reward modelling, and sim-to-real loops.

In this hands-on leadership role you will set the RL roadmap, design training and evaluation infrastructure, and mentor a small team to turn demonstrations into dependable production-ready behavior.

Qualificações

• Strong RL expertise with policy-gradient methods and offline RL.
• Hands-on robot learning/embodied AI experience with VLA models.
• Experience with sim-to-real and at least one major simulator (Isaac Gym/MuJoCo).
• Solid ML engineering with PyTorch and distributed training.
• Evidence of shipping policies from demo to production.

Responsabilidades

• Post‑VLA RL fine‑tuning — design and run the pipeline that takes a pretrained/imitation‑learned VLA policy and improves it with reinforcement learning (online and offline RL, RLHF/RL‑from‑feedback, preference and reward‑model approaches) to lift task success rates and reduce failure modes.
• Reward design & evaluation — define reward signals, success criteria, and automated evaluation harnesses that actually correlate with real‑world manipulation and whole‑body performance, and that catch regressions before deployment.
• Sim‑to‑real — build and tune the simulation‑to‑hardware transfer loop (domain randomization, residual policies, real‑world fine‑tuning) so gains in simulation hold up on the physical robot.
• Data flywheel — establish the loop that turns robot rollouts and teleop data into better policies: autonomous data collection, filtering, labelling, and continual retraining.
• Integration across the stack — work with the teams owning the orchestration layer, the VLA policy, and whole‑body control so RL improvements compose cleanly rather than fighting the rest of the system.
• Technical leadership — set the RL roadmap, make build‑vs‑adopt calls on frameworks and tooling, mentor engineers, and represent the work to the wider team and external partners.
