• 8+ years of relevant experience with digital radio systems such as GPS/GNSS receivers, satellite communications, or software defined radios
• Experience supporting external engineering teams integrating chipsets/modules/subsystems.
• Deep knowledge of GNSS receiver design and navigation algorithms.
• Hands-on embedded systems experience (ARM/DSP/FPGA; C/C++; Python; Linux; RTOS).
• Strong bench debug capability with RF and digital tools.
• Working knowledge of RF front-end design and PNT clocking (TCXO/OCXO, phase noise, holdover).
• Experience defining/executing test plans, including HIL and field testing.
• Proficiency with MATLAB/Octave or Python for simulation/analysis.
• Excellent communication skills and ability to build strong partner relationships.
• Analytical, independent, and comfortable working remotely across languages and time zones.
• Professional fluency in English.

Things That Would be Great if You Brought to the Table

• Master’s or PhD in Engineering, Computer Science, Aerospace Engineering, Physics, Applied Mathematics, or a related field
• GNSS interference testing experience and knowledge of anti-jam/anti-spoof techniques.
• Experience with European aerospace/defense/precision timing customers; familiarity with Galileo, OSNMA, and EU PNT standards.
• Background on defense/government PNT programs.
• Experience optimizing signal-processing partitioning or fixed-point/floating-point trade-offs.
• SDR platform experience (USRP, Pluto, HackRF, GNU Radio).
• Embedded Linux/system build expertise.
• FPGA development (VHDL/Verilog).
• Knowledge of GNSS/timing interfaces (NMEA, UBX, PPS, NTP, IEEE 1588).
• Experience in manufacturing bring-up and DFT.
• Experience with ITAR/EAR/TAAs on international programs.
• Professional proficiency in another European language.
• Prior in-region technical representative experience for a non-European supplier.

We’ll also need you to

• Be legally authorized to work in the European country in which you are based, without sponsorship
• Have ability to obtain entry authorization for the United States, United Kingdom and Schengen Area countries is required.
• Ability to travel up to 25 – 40%, primarily within Europe to partner sites and test ranges, with periodic travel to Iridium’s headquarters in Virginia, United States; a valid passport and the ability to obtain entry authorization for the United States are required
