About The Position

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. 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.

Requirements

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.

Nice To Haves

Experience with FEA or topology optimization.
Experience designing for robotic arms, mobile bases, or electromechanical systems.
Experience moving hardware from prototype to production.

Responsibilities

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.
