Mechanical Design Engineer

About the Role

Join a small, hands-on robotics hardware team building autonomous systems for industrial environments. You will take mechanical subsystems from concept through working prototype, helping turn robotic systems into reliable infrastructure.

What You'll Do

• Own mechanical subsystem design from initial sketches through prototyping and iteration, selecting appropriate materials, tolerances, and manufacturing methods.

• Create CAD parts and assemblies, supported by hand calculations and FEA, and optimize designs for rapid prototyping, 3D printing, and CNC machining.

• Build and iterate on prototypes using 3D printers, shop tools, and CNC equipment.

• Integrate mechanical designs with motors, sensors, electronics, and actuators on robotic arms and mobile bases.

• Work closely with electrical, software, and robotics teams to develop autonomous systems for production deployment.

What We're Looking For

• Two to five years of professional experience designing mechanical hardware for 6DOF robot arms or comparable multi-axis robotic systems.

• Experience taking physical robot prototypes from concept to working hardware, including mechanisms, joints, drivetrains, or end effectors, and shipping robotics hardware in a startup or small team.

• Proficiency with SolidWorks, Fusion 360, Onshape, or equivalent CAD tools.

• A BS in Mechanical Engineering or a related field, plus hands-on fabrication experience with 3D printing, CNC machining, and shop tools.

• Experience owning subsystems end to end, working independently in a fast-moving environment, and integrating motors, sensors, or actuators.

• Experience with FEA or topology optimization is valuable.
