Senior Propulsion Engineer

Los Angeles, California /
ABL Space Systems /
ABL's Senior Propulsion Engineers design and operate the engines and pressurization systems on the rocket, creating robust machines that just work, from propellant load through to payload deployment.

From propellant loading and management, pressurant, attitude control, and pneumatics to engine systems, the Senior Propulsion Engineer's scope is broad and multi-disciplinary. Good Senior Propulsion Engineers recognize that their ownership of a system is fully inclusive - they are responsible for dreaming, designing, developing, building, qualifying, and flying their hardware.


    • Take ownership of critical engine products (e.g. chamber, injector, turbopumps) and/or systems (e.g. pressurant, attitude control)
    • Define top level engineering requirements to meet business objectives
    • Identify and trade strategies to meet design requirements and select the right approach
    • Perform system sizing and analysis using hand calculations, custom scripts and more advanced analysis packages
    • Creates processes, systems, and tools that paves the way for a more streamlined workflow
    • Execute design work, considering manufacturing and operational constraints
    • Develop, test, and qualify the product
    • Develop production methodology and support initial builds
    • Design and build test hardware and production tooling

Basic Qualifications

    • B.S. in any engineering discipline from an accredited university
    • 6+ years of industry experience in a design, development, or systems role

Preferred Skills and Experience

    • Demonstrated ability utilizing CAD design software (e.g. NX, CATIA, CREO/PRO-E)
    • Demonstrated analysis capability using hand-calcs as well as finite element analysis (e.g. ANSYS, ABAQUS, NASTRAN)
    • Firm understanding of manufacturing processes and GD&T
    • Ability to program scripts in Python or MATLAB
    • Strong understanding of compressible/incompressible flow and thermodynamics
    • Aerospace hardware design and development
    • Writing and executing test procedures for complex hardware operations
    • Technical writing and communication including test plans and design reviews
    • Design, fabrication, and testing of fluid systems at elevated pressures and extreme temperatures

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.
