About the role
We're looking for a Mechatronics Manufacturing Engineer to build the test fixtures, assembly aids, and end-of-line test stations that let us build and validate humanoid robots reliably and at speed. This is a hands-on, build-it-yourself role that sits at the intersection of mechanical, electrical, and software work: you'll design a fixture's mechanical structure, wire up the sensors and actuators that drive it, and write the test code that runs it — then stand at the bench and make it work.
What they're looking for
- Bachelor's degree in Mechanical Engineering, Electrical Engineering, Mechatronics, or a related field, or equivalent hands-on experience
- 3+ years of experience working in a production environment building test fixtures, assembly tooling, or manufacturing test equipment, ideally in electronics, robotics, automotive, or similar hardware production environments
- Comfortable working across mechanical and electrical disciplines: you can design a simple mechanical fixture, wire up sensors and actuators, and write the code to make it all work together
- Practical CAD skills (SolidWorks, Onshape, Fusion, or similar) for fixture and tooling design
- Basic electrical skills: reading schematics, wiring test stations, using DAQ/PLC hardware or simple embedded controllers (Arduino, Raspberry Pi, microcontrollers)
- Programming ability in at least one language commonly used for test/automation (Python, C/C++, LabVIEW, or similar)

Persona AI is building humanoid robots for the most demanding environments in heavy industry — shipyards, steel mills, fabrication facilities, and offshore platforms — performing welding, grinding, maintenance, inspection, and material-handling work that is dangerous, physically demanding, and increasingly difficult to staff.
We are backed by leading strategic and financial investors and engaged with global industrial leaders across Korea, Japan, the United States, and Singapore. Korea is the center of gravity for our early commercial strategy, anchored by relationships with the world’s leading shipbuilders and steelmakers. Our work spans both the robot platform itself and the systems, partners, and playbooks required to deploy it at scale.
We offer competitive compensation, a performance-based bonus, 99% employer covered medical benefits, early-stage equity, competitive PTO, and a company-wide paid winter break between December 24th and January 2nd.
You’ll shape technology that’s redefining the possibilities of robotics and human interaction.
