About the Role
You will own the firmware layer for system level test of next-generation optical interconnect products. You will bring up and integrate firmware on SLT boards, build the test executive and datalog, run continuous regression on bench hardware, and carry test flows from engineering bring-up through board-level test to manufacturing partners. You will also mentor early-career engineers and set software discipline for the team.
