ABOUT FIREFLY AEROSPACE As an end-to-end responsive space company, Firefly Aerospace is on a mission to enable our world to launch, land, and operate in space - anywhere, anytime. Our small- to medium-lift launch vehicles, lunar landers, and orbital vehicles allow us to service the entire lifecycle of government and commercial missions from low Earth orbit to the Moon and beyond. We utilize carbon composite structures, patented propulsion technologies, and common components across our vehicles to iterate quickly, improve reliability, and deliver payloads at a lower cost. This position will sit at our our Rocket Ranch in Briggs, Texas.

Firefly's propulsion team is building and learning at a rapid pace and we are eager to see how experienced individuals thrive in this type of environment. RESPONSIBILITIES Assembly of engines, turbomachinery, and component hardware Perform leak checks and AVI checkouts on all hardware Disassemble and inspect tested engines, providing engineering insight on their hardware health Develop complex work instructions to improve build quality and ensure consistency Provide engineering desired changes to improve build quality and efficiency Inspect peer builds (two-person concept) Assist with development of support tooling Consistently improve
