Role summary
A company building autonomous robots for physical data center operations is seeking a Mechanical Design Engineer with 2-5 years of experience. The role involves owning robotic subsystems from concept to production, including material selection, tolerance definition, CAD design, and prototyping using 3D printing, CNC machining, and shop tools. Collaboration with the hardware team is key. Proficiency in CAD tools like SolidWorks, Fusion 360, or Onshape is required. Experience with FEA, robotic arms, mobile bases, or electromechanical systems is a plus.
About the company
Our client builds autonomous robots for physical data center operations. Its in-house hardware supports production infrastructure work including GPU repairs, cabling, SSD replacements, and rack buildouts. The team is looking for a hands-on mechanical engineer who wants to take complex robotic systems from concept through real-world prototypes.
The role
We are hiring a Mechanical Design Engineer to own critical robotic subsystems from early concepts through physical prototypes and production-ready designs. You will work across materials, tolerances, manufacturing, and integration, helping create reliable hardware for demanding real-world environments.
What you'll do
• Own mechanical subsystems from concept through prototype, test, iteration, and production.
• Select materials, define tolerances, and design for manufacturability.
• Create and refine parts, assemblies, and mechanisms using CAD.
• Build and test prototypes with 3D printing, CNC machining, and hands-on shop tools.
• Integrate motors, sensors, electronics, and actuators into robotic arms and mobile bases.
• Collaborate closely with the hardware team to solve practical engineering problems in deployed systems.
What we're looking for
• 2 to 5 years of relevant mechanical engineering experience.
• A bachelor’s degree in mechanical engineering or a related field.
• A strong portfolio showing concept-to-physical-prototype work in robotics or other hardware products.
• Proficiency with CAD tools such as SolidWorks, Fusion 360, Onshape, or an equivalent.
• Experience with 3D printing, CNC machining, and shop tools.
• Strong judgment around materials, tolerances, manufacturing, and mechanical integration.
Bonus points
• Experience with FEA or topology optimization.
• Experience designing for robotic arms, mobile bases, or electromechanical systems.
• Experience moving hardware from prototype to production.
Compensation and benefits
• Base salary of $150K to $250K.
• Competitive equity.
Location and work model
• Five days per week onsite in San Francisco.
• Full-time position.
• Visa sponsorship and transfers are not available.
