About the role

Working closely with mechanical, controls, electrical, and systems engineers, the team plays a critical role in reducing development risk, accelerating iteration cycles, and ensuring our robots are reliable, efficient, and production-ready.
As a Simulation Engineer, you'll help transform complex physical systems into predictive engineering models that enable faster development and better products.
Improve simulation fidelity through rigorous test correlation and continuous model refinement

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 scaling, we're hiring with intention, and we need people who want to build something that will genuinely change how humans spend their time - safely creating abundance for all.
Develop and own the simulation capabilities that guide critical engineering decisions across NEO's development.
Deliver validated thermal, structural, and multi-body dynamics models that accurately predict real-world system performance
Enable faster and more informed engineering decisions through design studies, tradeoff analyses, and sensitivity investigations
Support major product milestones by identifying design risks early and providing actionable recommendations backed by simulation data

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 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
Familiarity with manufacturing processes and design-for-production considerations

Comprehensive medical, dental, and vision coverage
Generous paid time off, company holidays, and parental leave
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

Develop scalable simulation workflows, automation tools, and best practices that increase engineering efficiency across teams
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
Experience validating models against real-world test data and improving predictive accuracy
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
We've been at this since 2014 and we're at the point where the hard problems are behind us and the hard work is in front of us.
