## Description

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.
