About Flexion

At Flexion, we're building the intelligence layer powering the next generation of humanoid robots. Our mission is to accelerate the transition from fragile prototypes to real-world humanoid deployment. We are founded by leading scientists in robot reinforcement learning (ex-Nvidia, ex-ETH Zürich), and backed by leading international VC firms. In just months, we've gone from our first line of code to deploying real humanoid capabilities.

The Role

We're looking for a Robotics Engineer to help close the gap between simulation and reality. As we deploy learned control policies onto physical hardware, the fidelity of our simulation is a critical factor in our success.

You will focus on the accurate modeling and system identification of in‑house and customer robots. You will work directly with the physical hardware to characterize sensors, drivetrains, and contact dynamics, accurately replicate these behaviors in our simulation environment,...
