Principal GNSS/PNT Systems Engineer

The Opportunity: We are seeking a Principal level GNSS / PNT Systems Engineer to provide technical leadership in architecting, developing, and validating advanced test solutions for CRPA antennas, GNSS receivers, and next generation LEO/MEO PNT signals. In this role, you will define system level test strategies, lead complex RF/signal simulation architectures, and shape the technical direction of future PNT capability development. You will work across RF, digital signal processing, and algorithm teams to ensure our PNT solutions meet the highest performance and resiliency standards expected in contested and evolving operational environments. Our Technology: Safran Federal Systems provides Resilient Positioning, Navigation and Timing (R-PNT) solutions and custom engineering services to U.S. Government agencies, defense organizations and their contractors. Safran Federal Systems is authorized to work on the full spectrum of U.S. Government classified and unclassified projects, in addition to supporting strategic partnerships for key defense PNT technologies. How I will Contribute: Serve as the technical authority for end‑to‑end test architecture development supporting qualification of CRPAs, GNSS receivers, and multi-orbit PNT signal sources. Develop and oversee complex scenario models—dynamic Doppler environments, orbital visibility profiles, threat scenarios, and mission-representative degradation conditions.
