About Us

UnitX builds the world's leading physical AI systems to automate repetitive visual tasks in factories. UnitX is a fast-moving startup with a team from Stanford, MIT, Google, and beyond. Since inception, UnitX has deployed 1,000+ mission-critical systems across 190+ of the world's leading manufacturers' production lines. Every year, $15B worth of products go through UnitX's AI inspection system to ensure quality.

The Role

As a Robotics intern, you'll work directly with our engineers on a prototyping robotic work cell—designing and fabricating parts, building up hardware, and running the robot during training. This is a hands-on role with fast design-build-test cycles and real ownership of hardware.

What You'll Do

  • Design parts for the robot cell in SolidWorks and fabricate them.

  • Prepare designs for outside fabrication (CNC machining, laser cutting) and communicate with vendors to quote and order parts.

  • Prototype and assemble mechanical designs.

  • Support testing, validation, and analysis of assemblies.

  • Set up and maintain robot cell hardware.

  • Operate and supervise the robot during training runs

All work is performed under the guidance of a senior mechanical engineer.

Requirements

  • Junior or senior pursuing a BS or MS in Mechanical Engineering, Mechatronics, or a closely related field

  • Proficiency in SolidWorks

  • Hands-on mechanical design and 3D printing experience (coursework, clubs, or personal projects)

  • Able to work 10–20 hrs/week on-site in Milpitas, CA

  • Authorized to work in the US for any employer

Nice to Have

  • Robotics experience (competition teams, research labs, coursework)

  • Familiarity with design for manufacturing (machining and laser-cutting constraints, tolerancing)

  • Understanding of lighting, camera and optical systems or is a photography enthusiast.

  • Experience sourcing parts or working with fabrication vendors

  • A portfolio of past projects (strongly encouraged)

Why Join

  • Get experience in a fast-paced engineering environment

  • Your parts go on a real robot, from CAD to hardware

  • Potential path to longer-term roles

  • Onsite lunch and dinner
