Propulsion Test Technician

Los Angeles, California /
ABL Space Systems /
ABL's Propulsion Test Technicians maintain critical hardware on the test site and test articles, ensuring they are mechanically sound and prepared for the next test.

Propulsion Test Technicians execute the manual operations and maintenance that keeps the test site and test articles running smooth. Their diligence prevents fittings and fasteners from coming lose, joints from leaking, and damaging debris from entering critical systems.


    • Build and maintain test facilities including propellant, high pressure, and cryogenic systems
    • Work alongside engineers to execute procedures for hazardous test operations, including engine hotfires
    • Troubleshoot and perform maintenance on fluid system, mechanical, and electrical systems
    • Work with engineers to build and maintain rocket engines and other test articles

Basic Qualification

    • 2+ years of industry experience working with aircraft, cryogenic fluids, high pressure systems, or combustion device testing

Preferred Skills and Experience

    • Able to diligently and safely follow hazardous test operation procedures
    • Operational experience with propellants, cryogenics, and high pressure systems
    • Proficiency with hand tools, lathes and drill presses, welding, electrical harnessing, forklifts and other light machinery
    • Ability to interpret plumbing and instrumentation diagrams (P&IDs)

Additional Requirements

    • The Propulsion Test Engineer must be willing to travel to launch and test sites to support integration and test operations
    • Must be able to stand for extended periods – 8 hours minimum
    • Must be able to stoop, bend, crawl, and being able to maneuver in tight spaces
    • Physically able to lift and maneuver items weighing up to 50lbs (unassisted)

What We Look For

    • 1. Critical thinking: ABL engineers understand the "why" behind all design decisions, operational events and test outcomes.  
    • 2. Ability to deal with ambiguity: there is no roadmap and ABL engineers must be comfortable defining their own pathway to an objective. 
    • 3. End-to-end ownership: projects are delivered fully complete and ready for flight; there is no one to pick up the slack of partially complete work.
