Propulsion Engineer, Engine Test

Mojave, California /
Engineering – Hardware Engineering /
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

Propulsion Engineer, Engine Test
ABL’s Engine RE (Responsible Engineer) team owns the successful performance of all ABL rocket engines. A Propulsion Engineer, Engine Test on this team is responsible for planning and execution of engine testing at ABL. This means formulating initial test plans, sitting on console for engine hotfires, performing data reviews, and leading anomaly investigations.

In this role you will work closely with test engineers and technicians to drive integration and test schedules that quickly buy down risk on ABL’s engine systems across development, qualification, and acceptance testing. You will own and maintain engine system schematics, balances, and sequences, while making decisions quickly and effectively. You’ll get your hands dirty inspecting engine hardware and will work closely with technicians to make changes to the hardware configuration. You will be responsible for increasing test cadence through automation and strategic scope reduction.

Engineers on the Engine RE team are highly motivated, proactive individuals who hold the highest level of accountability and drive a fast-paced environment at ABL’s test sites.
