The posting, in SpaceX's own words
archived Sep 2, 2026SpaceX was founded under the belief that a future where humanity is out exploring the stars is fundamentally more exciting than one where we are not. Today SpaceX is actively developing the technologies to make this possible, with the ultimate goal of enabling human life on Mars. PROCESS OPERATOR SPECIALIST, AIR SEPARATION UNIT (STARSHIP) SpaceX is building its first production-scale Air Separation Unit (ASU) at Starbase to produce the high-purity liquid oxygen that powers Starship. This is not just another industrial plant—it is the critical on-site propellant factory that eliminates supply risk for the most ambitious launch vehicle ever built and lays the operational foundation for producing propellants on the Moon and Mars. As a process operator specialist on the ASU team, you will operate and support cryogenic distillation, turboexpanders, centrifugal compressors, molecular sieve systems, and high-purity LOX production under the direction of Lead and Level 4/5 operators. You will monitor process parameters, execute approved procedures, complete thorough field rounds, and qualify toward independent watch standing. If you thrive in high-stakes cryogenic environments, want to learn these systems from first principles, and want ownership of mission-critical hardware as you grow, this is the role for you.
RESPONSIBILITIES:
Monitor the ASU via distributed control system/human-machine interface and conduct thorough field rounds, identifying equipment and process deviations early and reporting them immediately Execute assigned steps of plant startups, shutdowns, mode changes, and abnormal situation response in accordance with approved operating procedures and alarm response matrices Support troubleshooting, maintenance, and calibration of ASU equipment including centrifugal and reciprocating compressors, turboexpanders, cryogenic distillation columns, molecular sieve beds, gas analyzers, control valves, and instrumented electrical systems Collect process samples, perform basic field testing, log operational data accurately, and escalate immediately when plant conditions do not match the procedure Execute lockout/tagout (LOTO), permit-to-work, job hazard analyses, and Process Safety Management (PSM) activities as trained and authorized, and maintain rigorous 5S, housekeeping, and visual management Learn and qualify on standard operating procedures for major ASU systems, support shift pass-down, and participate in continuous improvement in reliability, purity, and housekeeping Learn and qualify on standard operating procedures for major ASU systems; build understanding of cryogenic thermodynamics, distillation, adsorption, and equipment performance through the ASU training and qualification gates Support shift pass-down and leave the board and field ready for the following shift; participate in continuous improvement in reliability, purity, and housekeeping
