jobs description


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.


The Fluid 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, integrating, and operating an efficient liquid propulsion system in a mass and performance critical rocket. As a Fluid Systems engineer you will work across the full lifecycle of hardware, including requirements definition, design, analysis, development, test, and qualification of the launch vehicle fluid systems. Your job will span CAD work of the system, supply chain management of your vendors, working at our test site integrating the system, propellant and commodity loading, participating in test and launch campaigns and much more! You will take profound ownership of your projects, and will collaborate with other product groups (structures, engines, avionics, vehicle 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.

• Develop new, innovative design concepts for fluid system integration and operations, that reduce and complexity and maximize reliability within cost
• Execute design for manufacturability changes to enhance production efficiency
• Identify and trade strategies to meet design requirements of flight hardware and tooling
• Make development decisions based on technical merit, risk, cost, schedule, and/or quality assurance
• Assist in the development of manufacturing, integration, and test processes, including work instructions, test procedures, and early build support
• Coordinate and execute development, qualification, and acceptance testing of flight hardware
• Work closely with production teams for integration and test of the fluid system
• Work closely with the operations team to develop fluid system operations plan for all phases of the mission
• Lead the interface with Systems Engineering and Range Safety related to all elements of 91-710 compliance

• BS in Mechanical or Aerospace Engineering
• 3+ years of experience in a related aerospace or mechanical field, with a focus in propulsion or fluid systems
• Experience leading technical reviews (design & analysis) or investigations (risk, anomaly, or trade studies)
• Proven experience in data review, data analysis, and report generation
• Experience in Siemens NX or equivalent CAD program
• Comprehension of design fundamentals including tolerancing, ASME Standards, ASTM, and GD&T
• Understanding of P&IDs, fluid system sizing, fluid component and instrumentation selection, fluid dynamics fundamentals, cryogenic systems and pressurized systems
• Experience with launch vehicle design, integration, and test

• MS or PhD in Mechanical or Aerospace Engineering
• Strong interpersonal and organizational skills
• Experience with liquid propulsion systems
• Familiarity with presenting trade studies, risks, schedules, requirements, and budget to program management or leadership
• Strong engineering fundamentals in compressible and incompressible flow, heat transfer, combustion devices, rocket engine cycles, and mechanics
• Experience with liquid rocket engine development, design, test, or flight operations
• Experience with liquid rocket engine subcomponent or pressurized component (valves, regulators, tubes, pipes, etc.) development, design, or test
• A passion for product optimization design and rapid manufacturing
• Hands-on experience with integrating test articles and sub-assemblies for test or production
• Proven experience in working with data acquisition systems and test instrumentation including pressure transducers, thermocouples, resistance temperature detectors, flow meters, load cells, and accelerometers
• Familiarity with some or all of the following software packages: Python, LabVIEW, GFSSP, Winplot, or other control, data acquisition, and reduction software
