Mechanical Engineer, Hands Prototyping

1X builds the world’s most dexterous humanoid hands in-house. We prototype
every day, break stuff, and ship real progress daily.

The job: Live inside the Hands team. Turn mech designs into working hardware
overnight. Be the guy everyone pings when they need a new finger, joint, or test
rig yesterday.

You’ll do:
- Same-day / next-day prototypes for the hand: mill, turn, print, cut, assemble,
solder
- Quick-turn CAD (Onshape/SolidWorks) part in hand bolted on robot→ →
- Build functional assemblies: tendons, sensors, skins, gears, whatever it takes
- Run abuse tests, cycle tests, drop tests on the bench
- Iterate mechs with the design team until it survives real use
- Hack test rigs so we can measure force, speed, precision fast
- Keep your corner of the shop stocked and machines running
- Document just enough so the next rev is faster

You need:
- 5+ yrs shipping real mechanical hardware (robots = huge plus)
- CAD all day, every day (Onshape preferred)

- Run 3-axis CNC, lathe, FDM/SLA printers, laser cutter without thinking
- Measure with calipers, micrometers, force gauges in your sleep
- Enough understanding of electronics to test on a system level
- Zero drama, just build it and make it work

Nice:
- Built or iterated robotic hands/end-effectors
- Vacuum casting, sheet metal tricks, custom fixtures
- Basic DAQ + Python/MATLAB for test scripts

Where You’ll Land
