Senior Fluid Systems / Process Design Engineer

As a Senior Fluid Systems Design Engineer in Ground Systems, you will develop the ground fluid infrastructure for safe, reliable rocket testing and launches. You’ll collaborate with propulsion and vehicle teams to translate requirements into robust fluid systems and operations concepts. You’ll tackle diverse challenges from design through commissioning, shaping facilities like engine test rigs and launch pads. This role offers hands-on impact across development, qualification, and site operations, with a clear path to leadership in system design reviews and tests.
