Mechanical Design Engineer

About this role

OpenAI's Robotics team seeks a Senior Mechanical Engineer to design and refine mechanical subsystems for advanced robotic platforms. You'll lead hardware development from prototype through production, collaborating with cross-functional teams to integrate mechanical components with AI and control systems in San Francisco.

What you'll do

• Lead mechanical subsystem design including structures, mechanisms, and actuators with proper tolerancing and documentation
• Build and test prototypes, troubleshooting fit, alignment, friction, and wear issues
• Develop test methods to validate performance, durability, and failure modes
• Support manufacturing transition and collaborate with production partners on assembly and process improvements
• Analyze test results and field data to drive iterative design enhancements
• Support sustaining engineering by investigating failures and implementing corrective actions

What they're looking for

• Mechanical system design (tolerance, alignment, load paths, wear analysis)
• CAD tools (NX, SolidWorks, or equivalent)
• Robotics and electromechanical systems
• GD&T and engineering drawing practices
• Manufacturing processes (machining, molding, fabrication)
• Prototyping and hands-on hardware debugging
• Design for Manufacturing (DFM) and Design for Assembly (DFA)
• Cross-functional collaboration and technical documentation
