SUMMARY As a Fluids Ground Support Equipment (FGSE) Engineer at Firefly, you'll own the complete lifecycle of critical fluid systems at our launch sites, test stands, and production facilities. You'll work in a dynamic and collaborative environment designing and building large complex fluid systems, including incompressible, cryogenics, propellants, and high-pressure gas systems. You'll be solving real-world problems in real-time alongside skilled technicians, welders, and cross-functional teams. From architecture trades and detailed designs through fabrication, installation, and activation, you'll be the technical decision-maker ensuring Firefly's launch sites and test stands meet the current and future needs for each of Firefly's programs.
This role offers exposure across Firefly's entire fleet - Alpha, Eclipse, Elytra, and Blue Ghost - giving you an unparalleled breadth of experiences and challenges as you help define the next generation of test and launch infrastructure.
RESPONSIBILITIES - Design, analyze, and build test stand and launch pad fluid systems, including incompressible, cryogenic, and high-pressure gas systems
- Own the full design cycle of your fluid systems, including generating schematics and P&IDs, sizing components, generating BOMs, creating CAD, procuring hardware, and generating drawings
- Work directly with technicians and welders to schedule, prepare, and build your designs and fix real-world problems
- Participate in and lead internal design reviews, operational readiness reviews, and represent Firefly during external design reviews
- Travel to test and launch sites, as required, to support build and commissioning of new and upgraded fluid system
QUALIFICATIONS Required - Bachelor's degree in mechanical engineering, aerospace engineering, or equivalent
- 2-5 years of recent experience in a professional setting outside the classroom with fluid systems, pneumatics, hydraulics, or HVAC systems in a design, assembly, test, or operations capacity
- Thorough understanding of fluid dynamics and thermodynamics
- Solid understanding of fluid components such as valves, regulators, pressure transducers, tubing, tanks, pressurized hardware, seals, and instrumentation
- Experience with fluid system subcomponent or pressurized component development, design, or testing (such as valves, regulators, piping systems, pumps, etc..)
- Working knowledge of manufacturing, fabrication, integration & quality control relevant to fluid components (such as machining, inspection, welding, assembly, testing, etc.)
- Demonstrated ability to do clean sheet designs of pressurization systems, propellant systems, or other complex multidisciplinary systems
- Experience creating P&IDs, performing fluid system sizing, fluid component and instrumentation selection, and pressurized system design
- Experience using fluids analysis tools such as REFPROP, GFSSP or other computer-based fluid dynamic modeling
- Proficient with 3D & 2D CAD software packages such as Siemens NX
- Capable of balancing detailed design tasks with higher level project management style tasks, including budgeting, scheduling, and communications
- Able to travel in support of GSE build and activation up to 30% of the time
Desired - Advanced degree in mechanical, aerospace, or equivalent field
- Direct hands-on experience building, troubleshooting, and/or operating complex fluid or mechanical systems
- Cryogenic system design and/or operational experience
- Hypergolic system design and/or operational experience
- Experience working in an aerospace, R&D, or oil & gas environment.
- Familiarity with ASME, NASA, and AFSPCMAN standards related to fluid system design, such as ASME B31.3, ASME BPVC Section VIII, and/or AFSPCMAN 91-710
- Direct experience with design and build of ground systems (GSE) or related fluid systems including, but not limited to test environments, fluid or gas conditioning/storage, manufacturing processes, and compressible gases
Firefly offers outstanding benefits for our employees, including generous health, dental and vision plans with low plan deductibles, parental leave, educational reimbursement, short term disability, and flexible PTO options.
