Job description
Signal Processing Engineer in the RF Processing & Analytics team, owning algorithms that detect, characterize and classify RF emitters for defense platforms. The role builds the classification and analytics layer that turns raw electromagnetic intercepts into a real-time electronic order of battle.

What you'll do
- Build algorithms to detect, deinterleave, and extract parameters (PRI, pulse width, frequency, modulation) from intercepted RF emissions.
- Develop classification pipelines — combining feature-based methods and machine learning — to identify emitter types and match them against threat libraries.
- Design the analytics that turn individual detections into a coherent, real-time picture of emitters, tracks, and threat posture.
- Apply machine learning to modulation recognition, anomaly detection, and emitter fingerprinting where it improves classification confidence in dense, contested spectrum.
- Work with signals captured by Radar, Radio, and Electronic Warfare to build a unified processing pipeline rather than siloed, single-sensor analysis.
- Take algorithms from offline prototyping (MATLAB/Python) to real-time or near-real-time implementation, alongside software and embedded/FPGA engineers.
- Validate detection and classification performance against simulated and real-world RF datasets, in lab and field-test conditions.
What we're looking for
- Master's or PhD in Electrical Engineering, Signal Processing, Applied Mathematics, or a related field.
- 3-6 years of experience in RF/radar signal processing, ideally with exposure to ELINT, ESM, or SIGINT applications.
- Strong fundamentals in DSP: spectral analysis, filtering, multi-rate processing, statistical/adaptive signal processing.
- Proficiency in Python and/or MATLAB for algorithm prototyping; working knowledge of C/C++ for production-oriented implementation.
- Comfortable applying machine learning to signal classification problems.
- Clear communicator, able to work across RF hardware, software, and data science disciplines.
- Fluency in English required.
Nice to have
- French is a plus.
