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.
