RF Test Engineer

The role

You will capture real signals from hardware and build systems to play them back through a channel simulator. You will develop test hardware, software, and a library of real emitter signals to validate satellite capabilities.

What you will do

• Capture real emissions using emitters like marine radars, AIS, ADS-B transponders, and satcom terminals
• Characterise captures into library entries with I/Q and measured parameters
• Build the generate and playback chain using SDRs, vector signal generators, and arbitrary waveform generators
• Build the channel simulator path applying delay, Doppler, path loss, multipath and interference
• Develop test hardware and software including fixtures, RF interconnect, and Python code for automation
• Inject signals into the flatsat, receivers and processing chain
• Work with the simulation team to align RF stimulus and simulated truth
• Keep operations lawful and safe regarding regulator, site safety, and RF exposure limits

Required qualifications

• Hands-on RF measurement and signal capture experience with spectrum and real-time signal analysers, vector signal generators, SDRs and oscilloscopes
• Experience building or integrating an RF record and playback, signal generation or hardware-in-the-loop test system
• Solid DSP fundamentals: sampling, I/Q, filtering, channelisation, Doppler and timing effects
• Python (or equivalent) for instrument control, automation and analysis
• Calibration discipline: reference planes, path loss and phase characterisation
• Clear written and spoken English

Nice to have

• Radar, ELINT, ESM or EW background
• Experience with channel emulators or fading simulators
• Satellite or LEO link simulation
• Multi-channel phase-coherent systems
• Precision timing (GPSDO, PPS, White Rabbit) or TDOA/FDOA test
• GNU Radio, MATLAB, UHD, VITA 49, SigMF
• Microwave work above 18 GHz, anechoic and screened-room operation, EMC test
• Field collection campaigns from masts, vehicles or aircraft
• Eligibility for national security clearance
