Basic qualifications: EducationMaster's degree (or higher) in Electrical Engineering, Aerospace Engineering, Physics, or a closelyrelated technical field. A Bachelor's degree may be considered with exceptional demonstratedexperience.

Experience: Minimum 10 years of professional engineering experience in GNSS systems engineering, RF systemsengineering, satellite payloads, TT&C design, or precision PNT system development. Demonstrated hands-on experience with at least two of the major GNSS constellations (GPS, GLONASS, Galileo) at the signal and systems engineering level — not limited to receiver integration. Proven experience designing or significantly contributing to precision time transfer systems, includingtwo-way time transfer (satellite or optical medium), with documented accuracy results at thenanosecond level or better. Demonstrated experience implementing Kalman filter-based navigation or timing solutions in real-world systems, with measurable performance results. Experience with RF systems engineering across S-Band and/or L-Band frequencies, including linkbudget derivation, antenna specifications, and receiver performance analysis. Proven track record managing RF hardware development cycles with external suppliers and definingstrict test and qualification parameters for flight hardware. Preferred qualification Experience designing a custom satellite-based PNT service from initial concept through operationaldeployment — including waveform design, ground terminal specification, and algorithm development. Practical experience with optical time transfer systems (White Rabbit, TWFTF) and integration ofoptical and RF time references in hybrid synchronization networks. Expertise in Alternative PNT (Alt-PNT) system design and evaluation, including non-GNSS positioningtechnologies and GNSS-independent timing sources. Experience with GNSS security: anti-spoofing detection, signal authentication (OSNMA, Chimera), andcryptographic protection of PNT services. Background in precise orbit determination (POD) and its integration into GNSS timing error budgets forhigh-accuracy applications.
