Software Engineer, Simulation

About 1X
We’re an AI and robotics company based in Palo Alto, California, on a mission to build a truly abundant society through general‑purpose robots capable of performing any kind of work autonomously.
We believe that to truly understand the world and grow in intelligence, humanoid robots must live and learn alongside us. That’s why we’re focused on developing friendly home robots designed to integrate seamlessly into everyday life.
We’re looking for curious, driven, and passionate people who want to help shape the future of robotics and AI. If this mission excites you, we’d be thrilled to hear from you and explore how you might contribute to our journey.

Role Overview
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.

Responsibilities

• 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

• 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 (preferred)

• Knowledge of extrinsic and intrinsic calibration algorithms for robotics (preferred)
  

Benefits & Compensation

• Salary Range: $130,000 – $250,000

• Health, dental, and vision insurance

• 401(k) with company match

• Paid time off and holidays
