RF Test Engineer
Core
Capture real RF emissions from hardware, characterize them into a library, and build a system to replay them through a channel simulator for satellite algorithm validation.
Role type
Senior IC RF Test Engineer (Signal Capture & Playback)
Builds
A library of real emitter signals with known truth and a coherent multi-channel playback system for satellite constellations.
Domain
Defense & Intelligence / Space Systems / RF Engineering
Required skills
RF measurement and signal capture, RF record and playback system integration, DSP fundamentals (I/Q, Doppler, timing), Python for instrument control, Calibration discipline
Preferred skills
Radar/ELINT/ESM background, Channel emulator experience, Multi-channel phase-coherent systems, Microwave work above 18 GHz
Technologies
SDRs, Vector Signal Generators, Arbitrary Waveform Generators, SigMF, GNU Radio, MATLAB, UHD, GPSDO, White Rabbit
Responsibilities
Capture real emissions from emitters (marine radars, AIS, satcom) in controlled setups, Characterize captures into documented library entries with I/Q and metadata, Build and calibrate the RF record and playback chain, Apply per-satellite delay, Doppler, and path loss in the channel simulator, Develop test hardware and Python automation code, Inject signals into the receiver chain to support algorithm validation
Seniority
Senior, hands-on IC
