About the job
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.
