You will build the hands that hold the torch. Persona AI’s humanoids weld, grind, and inspect in shipyards and heavy fabrication shops, and every one of those jobs comes down to a hand gripping a tool in a hot, dirty place and not letting go.
The hand is the hardest thing on the robot, the most parts, the tightest tolerances, and the smallest fasteners on the machine. It is also the part that decides whether the robot can do the work at all. Ours get built one at a time, by hand, in Houston.
This is fine-motor bench assembly under magnification: finger and thumb mechanisms built from miniature bearings, pivot pins, and linkages; drive tendons routed and pre-tensioned; fasteners torqued in newton-centimeters rather than foot-pounds. A dropped part is a lost part, and a quarter-turn too far is a stripped thread in a component with a long lead time.
Sensors, encoders, and motors arrive as sealed modules that you install mechanically and never open. You will work under ESD discipline, which we train and certify you on.
If you have spent years doing precise work with your hands — watches, instruments, medical devices, firearms, dental prosthetics, jewelry — this is that same craft, pointed at something new. We are not here to replace the trades. We are building machines that take on the worst jobs in heavy industry, directed by the crews who know that work best.
