As a Senior Spacecraft Software Test Engineer you will design, write, and debug tests to ensure that our flight software works as intended in orbit, working closely with a fast paced, agile software and GNC team. Your tests will include ‘test like you fly’ and ‘day in the life’ tests to execute the software like it will be operated in orbit in both the simulation and in a 'hardware in the loop' closed loop setup, integrating with hardware emulators and probing for off nominal situations and testing all of the commands through the integrated software.
