Propulsion Test Engineer

Los Angeles, California /
ABL Space Systems /
ABL's Propulsion Test Engineers are the lifeblood of any rocket engine development program, performing complex sets of procedures to bring the test articles to life.

Rocket engines are fickle machines that are intolerant to operational mistakes and it's the test engineers that keep them under control. While the test operations can be demanding, at the end of the day, the Propulsion Test Engineers are the ones creating smoke and flame. Great Propulsion Test Engineers strive understand the systems involved in the test articles so they can preempt any issues before they arise.


    • Design, commission, and operate test stands and GSE launch infrastructure
    • Create, review, and execute procedures for hazardous test operations, including engine hotfires
    • Manage test site logistics, including maintaining commodities and hardware
    • Troubleshoot fluid system, mechanical, and electrical issues
    • Work with software engineers to build, upgrade, and maintain test site software
    • Support test readiness reviews and test article data reviews

Basic Qualifications

    • B.S. in any engineering discipline from an accredited university
    • 2+ years of industry experience working with cryogenic fluids, high pressure systems, or combustion device testing

Preferred Skills and Qualifications

    • Operational experience with propellants, cryogenics, pyrophoric chemicals, and high pressure systems
    • Ability to interpret plumbing and instrumentation diagrams (P&IDs)
    • Experience with data acquisition and controls systems
    • Ability to program scripts in Python, MATLAB, or LabVIEW
    • Strong understanding of compressible/incompressible flow and thermodynamics
    • Writing and executing test procedures for complex hardware operations
    • Technical writing and communication including test plans and design reviews

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 25lbs (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.
