Principal GNSS Systems Engineer

What you'll do

• Lead the design and delivery of a custom satellite-based wireless positioning and timing transfer service.
• Own the GNSS subsystem architecture end-to-end from initial requirements definition through hardware acceptance.
• Model relativistic time corrections, ionospheric/tropospheric propagation, and CDMA spreading code correlation.
• Design and implement Kalman filter-based navigation and timing solutions for real-world systems.
• Perform RF systems engineering including link budget derivation and antenna specifications for S-Band and L-Band.
• Manage RF hardware development cycles with external suppliers and define flight hardware test parameters.
• Develop and integrate precise orbit determination into GNSS timing error budgets.
• Simulate signals and design filters using Python or MATLAB for automated test data analysis.

What we're looking for

• Master's degree in Electrical Engineering, Aerospace Engineering, Physics, or a related technical field (Bachelor's considered with exceptional experience).
• Minimum 10 years of professional engineering experience in GNSS systems, RF systems, satellite payloads, TT&C design, or precision PNT systems.
• Hands-on experience with at least two major GNSS constellations (GPS, GLONASS, Galileo) at the signal and systems engineering level.
• Proven experience designing precision time transfer systems with documented accuracy results at the nanosecond level or better.
• Demonstrated experience implementing Kalman filter-based navigation or timing solutions in real-world systems.
• Experience with RF systems engineering across S-Band and/or L-Band frequencies, including link budgets and receiver performance analysis.
• Proven track record managing RF hardware development cycles with external suppliers and defining flight hardware test parameters.
• Experience designing custom satellite-based PNT services, optical time transfer, Alt-PNT, or GNSS security (preferred).
