Job description

Job Summary:
1X is a company focused on building humanoid robots that assist with household tasks. They are seeking a Software Engineer - Simulation to develop and maintain simulation environments that enhance robot learning while reducing reliance on physical evaluations.
Responsibilities:
• Build and maintain the simulation environments and real-time infrastructure that accelerate robot learning at 1X, reducing dependence on physical robot evaluations, scaling synthetic data production, and ensuring policies trained in simulation transfer reliably to real hardware.
• Deliver diverse, physically realistic simulation environments for NEO that enable the AI team to develop and evaluate new policies without requiring real robot time for every iteration
• Measurably narrow the sim-to-real gap through domain randomization, calibration, and environment fidelity improvements, such that policies trained in simulation transfer reliably to deployed hardware
• Scale synthetic data production to meet the AI team's training needs, with infrastructure that generates diverse, high-quality simulation data efficiently and reproduces environments reliably
• Enable the hardware team to prototype and virtually test new robot hardware in simulation before manufacturing, reducing design iteration cycles and surfacing issues earlier.
Qualifications:
Required:
• 4+ years of experience programming in Python, C++, or similar languages, with experience building environments or benchmarks using robotics simulators (MuJoCo, PyBullet, Isaac Sim, or equivalent)
• Experience improving the performance of physics simulators or OpenGL rendering pipelines
• Strong testing practices for simulation stacks used in robot learning—comfortable writing tests that verify physical correctness and catch regressions
• Advanced degree (MS or PhD) in Computer Science or a related field
• Physics simulation depth understanding what makes a simulator physically accurate and computationally tractable; knows how to tune contact dynamics, articulated body models, and rendering fidelity for robot learning applications
• Sim-to-real instincts having practical experience narrowing the gap between simulated and real behavior; knows which differences matter for policy transfer and which can be addressed through domain randomization
• Performance-oriented engineer optimizing physics and rendering pipelines to maximize simulation throughput; thinks carefully about the tradeoff between fidelity and speed for different use cases
• Rigorous infrastructure builder writing tested, maintainable simulation code that other teams can depend on; treats correctness and reliability of the simulation stack as a first-class engineering concern
Preferred:
• Knowledge of extrinsic and intrinsic calibration algorithms for robotics, and experience using calibration to improve sim-to-real fidelity
• Experience with domain randomization, procedural environment generation, or other techniques for scaling diverse simulation data production
• Familiarity with differentiable simulation or GPU-accelerated physics (Warp, JAX-based simulators) for high-throughput parallel training
• Background in legged locomotion, dexterous manipulation, or contact-rich robotics where simulation accuracy is most critical
Company:
1X is an engineering and robotics company that develops humanoid robots designed to work alongside humans. Founded in 2014, the company is headquartered in Moss, NOR, with a team of 201-500 employees. The company is currently Growth Stage.
