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. Within a few months we’ve gone from our first line of code to deploying real humanoid capabilities with our partners. Learn more about Flexion at flexion.ai

The Role:

You’ll join the AI Engineering team, and work closely with the product and engineering team members. You'll collaborate directly with customers to ensure a seamless deployment of Flexion’s policies, serving as the technical bridge between R&D and the customer’s operational reality.

Key Responsibilities:

• Work directly with customers to ensure a seamless deployment of Flexion’s policies

• Retrain and fine-tune RL policies to function robustly on specific customer robots

• Execute the deployment and rigorous evaluation of trained policies on physical robot hardware, ensuring safety and performance benchmarks are met

• Own the end-to-end lifecycle of RL models for key accounts; monitor performance, manage data loops, and ensure consistent behavior across robot fleets

• Provide high-touch technical support (on-site or remote) during critical integration phases and deployments, troubleshooting complex interactions between neural networks and hardware
