Behind our business model is an exceptional team. Engineers, technicians and operators at ABL thrive on creating simple yet effective systems to tackle the challenge that space launch presents.  
Launch is just the beginning. Join ABL in paving the way for the next-generation space platform.

Lead Propulsion Engineer

ABL's Lead Propulsion Engineers own components and fluid systems throughout ABL's engines. They lead a team of engineers who work closely with a wide range of teams across ABL, including other hardware owners, stage systems, avionics, and instrumentation engineering, to deliver complex components and systems. Lead Propulsion Engineers own both the design and analysis sides of components and engine assemblies driving designs through development into production. They work closely with build and test engineers to ensure quality of design, ease of maintenance, and validation of designs through test. Strong Lead Propulsion Engineers apply as hands on methodical approach to problem solving and have exceptional fluid system and mechanical fundamentals.
