Senior DSP Engineer: RF Sensing & Geolocation

ApplyMint; Odense; On-site; DKK 700,000 - 900,000; Full time

Job summary

Quadsat is seeking an experienced Digital Signal Processing Engineer to join the RF team working on SpectraLoc, our defense product for detection, analysis, and geolocation of RF emitters.

You will design and implement DSP algorithms for signal classification, interference detection, and geo-localisation within Software Defined Radio systems, collaborating with RF, software, embedded, FPGA, and product teams to deliver robust sensing solutions.

Qualifications

• Hands-on experience developing and validating DSP algorithms on real RF data.
• Strong practical experience with digital signal processing for RF and SDR systems.
• Experience with SDR platforms and deployment constraints (real-time processing, latency, throughput).
• Knowledge of RF signal chains: sampling, bandwidth, filtering, SNR, synchronization, calibration effects.

Responsibilities

• Develop, validate, and mature DSP algorithms to improve RF sensing and geolocation capabilities.
• Design, prototype, and validate DSP algorithms for RF signal classification, interference detection, demodulation, and geo-localization within SDRs.
• Develop reference implementations and validation tools in Python, MATLAB, or similar environments.
• Work with recorded and live RF data to evaluate performance under noise, interference, and synchronization effects.
• Contribute to direction finding and RF sensing methods (AoA, TDOA, interferometry, beamforming).
• Define test methodologies, performance metrics, and acceptance criteria for DSP algorithms.
• Collaborate with software, embedded, FPGA, RF engineers to transition validated algorithms into product-ready implementations.
• Provide technical leadership within DSP and RF sensing teams.
