SUMMARY

As the Hypersonic Mission Architect, you will serve as Firefly’s senior technical authority for designing and leading end-to-end hypersonic mission architectures in support of hypersonic test, demonstration, and defense-focused missions, with specific emphasis on targets and countermeasures and suborbital access to hypersonic testing corridors. This position reports to the Director of Hypersonic & Strategic Defense Programs.

This role is a senior technical leadership position responsible for mission architecture from early customer engagement through proposal submission and into execution. You will architect missions spanning launch vehicle trajectory design, full boost-glide-payload systems, and integrated all-up-round (AUR) mission design, operating at both the mission and vehicle levels.

WHAT YOU’LL DO

• Lead end-to-end hypersonic mission architecture for test, demonstration, and defense missions including targets & countermeasures and suborbital corridor access
• Serve as Technical Lead and named Proposal Technical Lead for hypersonic pursuits, owning technical concepts, architectures, and proposal volumes
• Perform trajectory analysis and optimization, boost + glide staging trades, and intercept geometry analysis for integrated hypersonic missions
• Develop mission-level modeling and simulation environments to assess system performance, mission feasibility, and customer objectives
• Architect payloads, targets, and RV systems integrated with Firefly-adapted launch vehicles
• Design launch and space vehicle mission architectures supporting hypersonic applications
• Lead launch vehicle adaptation for hypersonic flight profiles, suborbital corridors, and test range integration
• Develop mission CONOPS across vehicle, payload, range, and customer interfaces
• Lead interdisciplinary engineering teams across guidance, navigation & control (GNC), propulsion, structures, payloads, and operations
• Interface directly with DoD customers, laboratories, and partners to shape future hypersonic test and demonstration architectures
• Support active programs through technical authority, architecture evolution, and flight execution support
