Mechanical Engineering Co-op

About the Role

• Design and build the physical hardware of teleoperated humanoid robots, including actuators, limbs, end effectors, and supporting structures.
• Own real parts and subsystems that will be integrated into the robot.
• Work closely with engineers on architecture, materials, and manufacturing decisions.
• Experience a fast-paced design cycle from sketch to finished product.

Key Responsibilities

• Design, build, and iterate on robot components and sub-assemblies (arms, hands, torso, actuators, end effectors) with full ownership.
• Support actuator and drivetrain development (e.g., harmonic, cycloidal, planetary reducers, belt and cable drives) through design, assembly, and testing.
• Rapidly prototype using in-house machining, 3D printing, and fabrication.
• Create drawings and prepare parts for manufacturing (CNC, sheet metal, 3D printing).
• Collaborate with vendors and machine shops for quotes and fabrication.
• Perform first-principles calculations (structural, thermal, kinematic) to validate design decisions.
• Build test rigs and fixtures, then iterate and harden hardware based on failures.
• Work with controls and electrical teams on sensor integration, cable routing, thermal management, and URDF/model accuracy.
• Assist with robot assembly, maintenance, and repairs, including field testing and customer demos.

Requirements & Tech Stack

• SolidWorks, Onshape, NX or similar CAD software.
• Design for manufacturing, tolerancing, and GD&T.
• Experience with mill, lathe, 3D printer or similar fabrication tools.
• First-principles calculations (structural, thermal, kinematic).
• Experience with sensor integration, cable routing, thermal management, and URDF/model accuracy.

Qualifications

• Currently enrolled in a Bachelor’s or Master’s program in Mechanical Engineering, Mechatronics, Aerospace Engineering, Robotics, or a related field.
• Strong CAD skills, with a portfolio of designed and built parts or assemblies.
• Solid understanding of mechanisms, materials, fasteners, bearings, and power transmission.
• Hands-on fabrication experience using machining or 3D printing tools.
• A bias for action and comfort with fast-paced development.

Bonus:

• Serious personal hardware projects or design team experience (e.g., Formula SAE, rocketry, robotics competitions, custom CNC or vehicle builds).
• Previous co-op or internship at a hardtech company (robotics, aerospace, defense, EV).
• Experience with robotic actuators, legged robots, humanoids, or dexterous hands.
• Exposure to designing for harsh or hazardous environments.
• FEA or thermal simulation experience (ANSYS, Abaqus, or similar).
