Spacecraft Propulsion Systems Engineer
ABOUT FIREFLY AEROSPACE
Firefly Aerospace Inc. is an American end-to-end space transportation company committed to providing economical and convenient access to space for small payloads through the design, manufacture, and operation of reliable launch and spacecraft vehicles.
We are achieving this by supporting a work culture that empowers employees to dream big as they enable new technology innovations with game-changing efficiencies in LEO, on the Moon, and beyond. We are looking for incredibly passionate, bright innovators to join our team as we deliver game changing commercial products to space.
The Propulsion Systems team at Firefly is integrated within the Propulsion and Fluids department. Our team is responsible for all fluid subsystems across our launch vehicles and spacecraft. In this role you are challenged with designing and integrating an efficient hypergolic propulsion system in a highly mass critical lunar lander. You will work across the full lifecycle of hardware, including requirements definition, design, analysis, development, test, and qualification of our spacecraft fluid systems. Your job will span CAD work of the system, supply chain management of your vendors, working in the cleanroom integrating the system, propellant loading, participating in the in-space operations and much more! You will take profound ownership of your projects, and will collaborate with other product groups (structures, fluid systems, avionics, vehicle/spacecraft systems) to make critical decisions. We are looking for someone who’s a self-starter, enjoys questioning the status quo, and working in a dynamic and cross-disciplinary team.
- Own spacecraft fluid systems requirements and design from start-to-finish
- Develop new and innovative design concepts for propulsion integration and operations that reduce complexity and maximize reliability within budget
- Assist in the development of manufacturing, integration, and test processes, including work instructions, test procedures, development testing, and initial build support
- Act as the primary point of contact for design, analysis, and operations of spacecraft fluid systems
- Coordinate and execute development, qualification, and acceptance testing of flight hardware
- Execute design for manufacturability changes to enhance production efficiency and vehicle reliability
- Identify system risks and conduct corresponding trade studies to ensure successful vehicle operation
- Drive development of automation and test data analysis tools
