Company Description

PAL Robotics is a leading service robotics company based in sunny Barcelona. Our goal is to enhance people's quality of life through robotics and automation technologies. We have over 20 years of experience in the robotics field and offer daily challenges to everyone in our team to help them grow.

Job Description

We are looking for a Robotics Engineer specialized in Reinforcement Learning (RL) to develop, deploy, and validate control policies on real robotic systems. You will work at the intersection of simulation and hardware, building robust policies in simulation (MuJoCo / MJLab) and transferring them to real robots with high reliability. This role requires strong expertise in policy learning, sim-to-real transfer, and system identification, as well as hands-on experience validating behaviors on physical platforms.

Primary duties:

Develop RL-based control policies for robotic systems using MuJoCo and MJLab.
Design and train locomotion and manipulation policies, including walking, balancing, grasping, and object interaction.
Implement and compare pure reinforcement learning approaches with imitation learning methods like behavior cloning and offline RL.
Deploy and validate trained policies on real robot hardware to ensure effective performance.
Bridge the sim-to-real gap using system identification, domain randomization, and actuator/dynamics modeling.
Analyze failures and iterate on models, reward functions, and training setups to improve performance.
Integrate policies into existing robotics stacks, such as ROS 2-based systems.
Collaborate across teams, interfacing with control, perception, and hardware specialists.
