Software Engineer, Simulation Location: Palo Alto, CA (on-site) About 1X We build humanoid robots that work alongside people to solve labor shortages and create abundance. The Role You will design and build simulation environments and real-time infrastructure to accelerate robot learning. Your work enables the AI team to iterate rapidly on research by reducing dependence on real robot evaluations, constructing realistic simulation environments, and scaling simulation data. You’ll help bridge the gap between simulated and real robot behaviors, prototype new hardware in simulation, and support evaluation and training tasks across teams. You Will - Construct diverse, physically realistic environments for NEO in simulation - Close the sim-to-real gap between policies trained in simulation and deployed on real robots - Scale up the production of simulation data for research usage - Collaborate with AI and teleoperation teams to develop new training and evaluation tasks and ensure they run performantly - Work with the hardware team to prototype new robot hardware and test it virtually in simulation Must Have - 4+ years of experience programming in Python, C++, or similar languages - Experience building environments and benchmarks using robotics simulators such as MuJoCo, PyBullet, or Isaac Sim - Experience improving performance of physics simulators or OpenGL rendering pipelines - Experience with testing practices to maintain correctness of simulation stacks used for robot learning - Courage to tackle unsolved technical challenges with strong work ethic - Advanced degree (MS or PhD) in Computer Science or related field - Knowledge of extrinsic and intrinsic calibration algorithms for robotics Benefits & Compensation - Salary Range: $130,000 – $250,000 - Equity - Health, dental, and vision insurance - 401(k) with company match - Paid time off and holidays Equal Opportunity Employer 1X is an Equal Opportunity Employer.
