Senior Ground Fluid Systems Engineer

Los Angeles, California /
Engineering – Hardware Engineering /
/ On-site
ABL Space Systems was founded in 2017 by veterans of SpaceX and Morgan Stanley to develop low-cost launch vehicles for the small satellite industry. More importantly, we’re building a launch system we are truly proud of – no gimmicks or over-design, just reliable, rapidly deployable launches. We’re an ambitious team with big goals and, together, we’re determined to prove that reaching space can be simple, efficient, and routine.  

When launch day arrives, we want you by our side

As a Senior Ground Fluid Systems Engineer, you will lead the development, design, build, and commissioning of ground fluid systems at ABL to support tests, operations, and launches.  You will have the opportunity to be a key member of a small team of mechanical, fluid, and electrical engineers working to develop innovative deployable launch solutions that enable the rapid deployment and launch of ABL orbital vehicles. This is a role that contributes to every mission and every flight we fly as we continue to reimagine the future of space launches.


    • Take full ownership for designing ground fluid systems from clean sheet design, through commissioning
    • Perform fluid system sizing and analysis using hand calculations, custom scripts, and more advanced analysis packages
    • Develop fluid and pneumatic systems to support RS1 ground operations that comply with ABL, Test Site and Range requirements. Work with mechanical and electrical engineers to ensure clean cross functional design
    • Develop test plans for ground fluid systems, and lead ATP/checkouts testing to verify functionality. Inclusive of planning, documentation, and execution of test campaigns
    • Lead the development of internal standard manufacturing/integration processes (fabrication, inspection, etc.) that comply with ABL, Test Site and Range requirements and deliver quality ground fluid systems
    • Create and present internal technical documentation that clearly conveys design intent, adherence to standards, requirements, and specifications
    • Prepare and effectively deliver technical regulatory documentation to support launch site deployments, system level checkout operations, and flight license approval
    • Manage project’s schedule, compliance with internal and external requirements, budget, milestones, and track status
    • Interface with technicians to coordinate builds, logistics, support, and requirements
    • Mentor other engineers and technicians on the team
    • Ability to travel up to 25% of the time


    • Bachelor’s Degree in Mechanical, Aerospace, or similar field
    • Minimum 5 years of experience working in space, aerospace, or equivalent professional environments with direct hands-on experience developing complex fluid systems
    • Ability to size fluid components based on flow, pressure, and thermal requirements
    • Experience using fluid components
    • Experience routing fluid and electrical systems in complex assemblies
    • Experience working across engineering groups to define requirements and implement solutions
    • Demonstrated ability utilizing CAD design software (e.g. NX, CATIA, CREO/PRO-E)


    • M.S. from an accredited university in engineering or science
    • Experience working with high-pressure systems
    • Experience working with modeling tools like GFSPP or similar
    • Experience working with cryogenic fluid systems
    • Understanding of manufacturing processes and GD&T
    • Experience with Teamcenter or other PLM system
    • Good understanding of industry standards such as: AFSPCMAN 91-710, NASA-STD-5005
    • Ability to develop and review complex fluid P&IDs


    • Critical thinking: ABL engineers understand the “why” behind all design decisions, operational events and test outcomes
    • Ability to deal with ambiguity: ABL engineers must be comfortable defining their own pathway to an objective
    • End-to-end ownership


    • Ability to sit or stand for extended periods of time
    • Ability to use a computer to complete assignments
