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

SUMMARY

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.

RESPONSIBILITIES

• 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
