Senior SIGINT / RF Sensing & Signal Processing Engineer

As a Senior SIGINT / RF Sensing & Signal Processing Engineer, you own the complete RF sensing chain from antennas and raw IQ data to detected, characterised, classified and geolocated information.

You will develop airborne and ground-based capabilities for spectrum awareness, emitter analysis, jammer and spoofer localisation, recording, replay and operator visualisation. Using SDRs, coherent receivers and edge computing, you will turn sensing concepts into calibrated operational systems.

• Define RF sensing architectures and budgets covering sensitivity, dynamic range, bandwidth, scan rate, timing, storage, coverage and SWaP-C.

• Select and integrate antennas, filters, LNAs, switches, SDRs, coherent receivers, timing sources and edge-compute hardware.

• Develop capture, channelisation, filtering, FFT, detection, feature-extraction, recording, metadata and replay pipelines.

• Characterise signal presence, frequency, bandwidth, occupancy, modulation features, pulse behaviour and emitter activity.

• Develop classification and prioritisation methods with quantified confidence, detection probability and false-alarm behaviour.

• Design and validate direction-finding and geolocation using AoA, TDOA, FDOA, coherent arrays or distributed sensors.

• Develop localisation capabilities for GNSS-band interference and other mission-relevant emitters.

• Create calibration methods for receiver gain, frequency error, phase coherence, timing and antenna-pattern effects.

• Integrate platform position, attitude, timing and ground truth into repeatable geolocation solutions.

• Build secure data pipelines, operator visualisations, datasets and emitter libraries with traceable metadata.

• Execute laboratory, ground, range and airborne tests against known emitters and measured ground truth.

• Collaborate with RF, software, avionics and flight-test engineers to mature capabilities for controlled release.
