SUPO, where required)Why This Role MattersAs an RF Test Engineer, you'll capture real signals from real hardware and build the system that plays them back through a channel simulator. Our processing, on the ground today and on board from Gen 2, is only as good as the signals we test it against. To our customers we provide intelligence with unmatched quality, latency and revisit times, in any weather, day or night. ICEYE-built constellations serve customers in defence and intelligence, environmental monitoring, insurance and emergency management. Founded and headquartered in Finland, ICEYE operates globally with over ***
* employees across Europe, North America, the Middle East, and Asia-Pacific.
Your Day-to-day ResponsibilitiesCapture real emissions: bring emitters into the lab (marine radars, AIS and ADS-B transponders, satcom terminals, partner-supplied equipment), operate them in a controlled, screened setup, and record them at the right bandwidth, dynamic range and timing accuracy. Build the channel simulator path: apply per-satellite delay, Doppler, Doppler rate, path loss, multipath and interference to recorded and synthetic signals, phase-coherently across channels and driven by geometry from the simulation software.
Develop test hardware and software: fixtures, RF interconnect, switching, attenuation and calibration paths, plus the Python code that controls and automates your instruments,



so every measurement runs as a script.
Keep operations lawful and safe: work with the regulator, site safety and partners on screened operation, test identities (MMSI, ICAO address) and RF exposure limits for everything that transmits.
