Propulsion Systems Engineer

Los Angeles, California /
ABL Space Systems /
ABL's Propulsion Systems Engineers bring all the vehicle's fluid systems together with a streamlined network of tubes and manifolds.

Propulsion Systems Engineers work closely with all engineering disciplines to bring system schematics to life. They take delight in creating a system layout that balances the mechanical requirements of each part and the complexity of the resulting fluid lines. Good Propulsion Systems Engineers are organized, methodical, and have exceptional spatial awareness.


    • Determine fluid line sizes, thickness, materials, and interfaces
    • Convert system schematics to flushed out 3D models in CAD, considering manufacturing, integration, and operational constraints
    • Design and analyze fluid systems and component support structures
    • Performed combined loads analysis to determine interface loads
    • Quantify system restrictions
    • Develop production methodology and support initial builds
    • Performs trade studies related to gas and propellant budgets

Basic Qualifications

    • B.S. in any engineering discipline from an accredited university
    • One of the following experience bases:
    • ‍2+ years of industry experience in a development, integration & test, or design role
    • Collegiate internship or co-op, hands-on extracurricular projects, or similar engineering activity

Preferred Skills and Experience

    • Ability to create and interpret piping and instrumentation diagrams (P&ID)
    • Experience with design and analysis of aerospace fluid systems
    • Knowledgeable with CAD and FEA systems
    • Familiarity with thermofluid analysis tools such as GFSSP, ROCETS, Thermal Desktop, ANSYS Fluent
    • Strong understanding of thermodynamics, compressible/incompressible flow, and real fluid properties using tools such as REFPROP, CoolProp, GASP
    • Familiarity with fluid system design elements, including valves, tubing, flexible elements, flanges, fittings
    • Firm understanding of tubing manufacturing methods, including bending, flaring, and welding
    • Technical writing and communication including manufacturing plans and design reviews

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
