Firefly Aerospace, Inc. seeks an experienced Fluids and Ground Systems Engineer to design, build, and operate critical fluid systems for a growing launch-site portfolio.
You will own cradle-to-grave work from concept through live operations, including cryogenic propellants and high‑pressure gases. The role demands 7+ years in mechanical, propulsion, or fluid systems, strong analytical skills, and the ability to collaborate across diverse teams and time zones.
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 build enable the next launch.
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.
