Simulation Engineer

1X • San Carlos, CA

2d • Onsite

About The Position

1X is building humanoid robots designed to work in homes, handling chores and tasks to give people their time back. This requires solving complex problems in robotics, AI, and manufacturing simultaneously and at scale, with a product safe enough for family life. The Simulation team is crucial in enabling faster, smarter engineering decisions by creating accurate digital representations of the NEO robot and its subsystems. They develop models and tools for predicting performance, understanding failure modes, and optimizing designs before hardware is built. This role involves close collaboration with mechanical, controls, electrical, and systems engineers to reduce development risk, accelerate iteration cycles, and ensure robot reliability, efficiency, and production readiness. The Simulation Engineer will develop and own simulation capabilities to guide critical engineering decisions, optimize performance, validate designs, reduce risk, and improve reliability across various robot subsystems. The work involves transforming complex physical systems into predictive engineering models for faster development and better products.

Requirements

• Bachelor's or Master's degree in Mechanical Engineering, Aerospace Engineering, or a related field.
• 5+ years of professional experience in thermal, structural, dynamics, or multiphysics simulation.
• Proficiency with industry-standard simulation tools such as ANSYS, Abaqus, COMSOL, MSC Adams, or equivalent.
• Strong understanding of heat transfer, structural mechanics, materials, and system dynamics.
• Experience developing and validating simulation models using experimental test data.
• Deep understanding of physics-based modeling, including thermal, structural, and dynamic systems.
• Strong analytical mindset with the ability to translate ambiguous engineering challenges into robust simulation frameworks.
• Strong cross-functional collaboration skills and ability to communicate complex technical findings clearly.
• Ownership mentality with a bias toward execution, continuous improvement, and engineering rigor.

Nice To Haves

• Experience modeling robotic, electromechanical, or actuator-driven systems.
• Experience performing fatigue, vibration, durability, or reliability analyses.
• Proficiency with Python, MATLAB, or similar scripting languages for workflow automation and post-processing.
• Experience building simulation infrastructure, templates, or engineering best practices.
• Familiarity with manufacturing processes and design-for-production considerations.

Responsibilities

• Deliver validated thermal, structural, and multi-body dynamics models that accurately predict real-world system performance.
• Improve simulation fidelity through rigorous test correlation and continuous model refinement.
• Enable faster and more informed engineering decisions through design studies, tradeoff analyses, and sensitivity investigations.
• Develop scalable simulation workflows, automation tools, and best practices that increase engineering efficiency across teams.
• Support major product milestones by identifying design risks early and providing actionable recommendations backed by simulation data.

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
