Job Description

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.

Job Responsibility

  • 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

Requirements

  • 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 to have

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

What we offer

  • Comprehensive health, dental, and vision insurance
  • 401(k) with company match
  • Paid time off and holidays
  • Equity
