About Lumen Labs

Lumen Labs is building the cognitive layer for physical AI. Nearly every major robotics effort today relies on teleoperation; we’re developing nature-inspired architectures for unstructured environments (construction sites, mining, pipelines, battlefield). Pre-seed, backed by top VC funds and operators from robotics/AI companies. A small team (two founders) hiring teammate #3 to own the hardware and infrastructure that keeps our research platforms running: the ROS2 (Humble) stack across onboard and offboard compute, sensor integration and calibration (LiDAR, depth, IMU, encoders), the safety pipeline during autonomous runs, and getting trained policies onto real hardware.

Job Description

Own “the gauntlet,” our test library for putting new architectures through their paces: a Gymnasium-style interface on both sides (environment and model) so anything built to spec is compatible with everything else. Mostly MuJoCo and Gazebo today, moving toward Isaac Sim, and some other more bespoke sims. You will be building task simulators for training and testing and keeping them running (GPS-denied drone nav, construction sites, boat cleaning, forklifts, abstract control), including physics, honest sensor models, digital twins of our real platforms, domain randomization, and the sim compute. Dungeon Master. If you have built or substantially rebuilt a simulator of some kind (robotics/RL is closest, but a physics-based game, scientific sim, or flight sim mod counts) this would be a good role for you. Comfortable with the Gymnasium/dm_control way of thinking, can pick up GPU-vectorized sim (MJX, Isaac Lab, JAX) quickly, and test-driven.
