Senior to Staff Tools Engineer, Simulation

1X • San Carlos, CA

3d • Onsite

About The Position

We’re building humanoid robots that work in home - doing the chores, handling the tasks, and giving people their time back. NEO is our flagship - a home robot designed to move, learn, and operate in the real world alongside real people. We’re not demoing it - we’re shipping it. The Tooling team builds the tools, pipelines, and infrastructure that speed up iteration and give us confidence our software works properly before it reaches physical robots. This team turns our simulator into a first-class tool that is easy to use, extensible by developers, and accurate to our robot’s unique hardware – leveraging game engine assets and expertise to accelerate the development of embodied AI.

Requirements

• Deep expertise building developer tooling, simulation platforms, or game engine infrastructure.
• Strong systems thinking with experience designing scalable content pipelines and engineering workflows.
• Experience creating easy to use tools that empowers developers, designers, or technical artists.
• Excellent software engineering skills with a focus on performance, maintainability, and automation.
• Comfortable driving technical direction across multidisciplinary teams in a fast-moving startup environment.
• 6+ years of professional experience (Senior) or 10+ years (Staff) developing game engine tooling, simulation platforms, developer tools, or large-scale content pipelines.
• Bachelor's degree in Computer Science, Software Engineering, Game Development, or a related technical field.
• Strong proficiency in C++, C#, Python, or similar programming languages.
• Experience developing tools within Unreal Engine, Unity, proprietary game engines, or large-scale simulation environments.
• Experience building CI/CD pipelines, automated testing frameworks, or deployment systems for engineering workflows.

Nice To Haves

• Experience building simulation platforms for robotics, autonomous systems, gaming, or digital twins.
• Experience developing end-to-end asset and content management pipelines, including import, validation, versioning, packaging, and deployment.
• Background as a Technical Artist, Tools Engineer, Build Engineer, or Engine Programmer with strong software engineering fundamentals.
• Familiarity with source control systems, build automation, cloud infrastructure, and continuous integration technologies.
• Experience developing tools for large multidisciplinary teams, including engineers, artists, designers, researchers, or simulation developers.
• Familiarity with ROS/ROS2, robotics simulation platforms (Isaac Sim, Gazebo, MuJoCo), or physics engines.

Responsibilities

• Design and build scalable tooling that enables robotics engineers to efficiently create, manage, and test simulation environments throughout the development lifecycle.
• Improve end-to-end simulation content pipelines, including asset ingestion, environment creation, versioning, validation, and deployment workflows.
• Integrate simulators into automated testing frameworks and CI/CD pipelines that continuously validate robot behaviors across large simulation environments before production deployment.
• Build internal tools that improve developer productivity, reliability, and engineering velocity across all 1X software teams.
• Establish scalable platform architecture and engineering best practices that support long-term growth of the simulation ecosystem.

Benefits

• Comprehensive medical, dental, and vision coverage
• Generous paid time off, company holidays, and parental leave
• 401(k) plan with company match (100% on the first 3% of contributions, 50% on the next 2%)
• Flexible Spending Accounts (FSA) and Health Savings Accounts (HSA) options
• Commuter benefits (transit and parking)
• Short-term and long-term disability, and life insurance
• Employee Assistance Program (EAP) for mental health, financial, and personal support
• Onsite snacks and catered lunches
