ABOUT FIREFLY AEROSPACE

As an end-to-end space transportation company, Firefly Aerospace is on a mission to enable our world to launch, land, and operate in space – anywhere, anytime. Our launch vehicles, lunar landers, and orbital vehicles provide government and commercial customers with full mission services from low Earth orbit to the surface of the Moon and beyond. Headquartered in north Austin, Texas, Firefly is looking for passionate, hardworking innovators to join our team and help fuel our successful trajectory into space.

SUMMARY

As a Senior Propulsion Engineer you will leverage your creativity, ingenuity, and experience to produce the next generation of rocket engines for space exploration and accessibility. At Firefly we strive to make the world’s most reliable rocket engine by decreasing complexity to increase reliability and performance while lowering cost. In this role you will produce innovative solutions to challenging problems throughout a project’s full life cycle, including design, analysis, manufacturing, testing, and operational support. You will take profound ownership of your projects, and will collaborate with other departments and product groups (propulsion manufacturing, vehicle systems, avionics, test operations, ground support engineering) to make critical decisions. To be successful in this role, you should embrace challenging problems and be able to synthesize disparate pieces of information to establish the best path forward. Your passion and determination will create leading edge propulsion systems in a fast-paced environment.

RESPONSIBILITIES
