Mechanical Design Engineer

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. Requirements 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. Benefits 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.
