Launch Engineer IV- Fluid Systems

Firefly Aerospace is a space and defense technology company on a mission to reliably and repeatedly launch, land, and operate space systems from Earth to the Moon and beyond. As the partner of choice for critical space missions, Firefly is the first commercial company to launch a satellite to orbit with 24-hour notice and the first company to achieve a successful Moon landing.

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 position can be located in the following states CO, CA, TX, FL, VA.

The Launch Site Development team is hiring for high-impact, dynamic engineering positions for those who thrive on solving real problems in diverse environments. Design, commission, and operate mission-critical fluid systems across a growing portfolio of launch sites, from historical US-based pads to greenfield builds in extreme locations including Wallops Flight Facility and Esrange, Sweden. Take cradle-to-grave ownership of critical launch systems for cryogenic propellants, high-pressure gases, payload environmental control, and other ground support equipment.

You'll work with world-class design and operations teams to create adaptable designs that deploy reliably across wildly different site conditions and constraints. Expect your work to matter immediately: concepts become hardware, installations support live operations, and the systems you built enable the next launch.

• Design, build, and activate new fluid systems across a global launch portfolio including Vandenberg Space Force Base (CA), Wallops Flight Facility (VA), Cape Canaveral Space Force Station (FL), and Esrange Space Center (Sweden)
• Lead design reviews and collaborate with multidisciplinary teams — including design engineers, technicians, external partners, and site personnel — to drive fluid system upgrades, streamline operations, and establish standardized processes across all launch sites
• Commission ground systems and lead integrated vehicle/ground operations at the pad
• Lead troubleshooting efforts, resolve any issues and non-conformances that arise during operations/testing, and support anomaly investigations
• Opportunities to perform launch console operations or launch day red team activities
• Write procedures and automation for launch pad configuration, vehicle operations, and propellant/pressurant handling during countdown operations
• Develop and execute maintenance strategies that maximize system availability and minimize downtime between missions
• Lead development of company processes, guidelines, and training in test and launch operations
• Collaborate with customers, external stakeholders, and design teams to ensure interoperability and compliance with regulatory and range safety requirements
• Provide technical write-ups for proposals and tailoring of regulations
• Guide the work of early career Fluids and Mechanical GSE team members and support hiring efforts
• Requires up to 25% travel to test and launch sites to support overall program needs

• Bachelor's degree in mechanical engineering, aerospace engineering or related engineering discipline
• 7+ years of hands-on experience with mechanical systems, structural systems, propulsion systems, fluid systems, flight hardware or test operations
• Experience designing, building, troubleshooting and/or operating complex fluid systems
• Demonstrated experience with interpretation and design of P&IDs
• Experience with hazard and risk analysis tools (i.e., FMEA, FMECA, FHA, HAZOP, etc.)
• Able to prioritize and execute tasks in a high pressure fast-paced environment
• Ability to self-motivate and take the initiative to ensure your…
