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 talented and highly motivated robotics software engineer to join our team in Zürich. In this role, you will work closely with our customers, AI engineering team, testing team and the rest of the company to drive successful deployments of our groundbreaking humanoid autonomy stack. You will have ownership of the integration, validation and deployment of our AI systems with novel, state-of-the-art humanoid hardware. At the same time, you will contribute to our core platforms and tooling for deployment and testing to enable scalable customer growth. This is a unique opportunity to join our world-class team of engineers and scientists and to build many aspects of our foundational software from the ground up.
