What you'll do
- Design modulation, coding, and equalization schemes for a robust, low-latency radio link.
- Build algorithms that keep the radio link alive under active jamming (ECCM).
- Detect and characterize other radio emitters in the operating environment (SIGINT).
- Optimize mesh networking protocols so multiple radio units share the airwaves without collision.
- Apply machine learning to jamming detection and channel prediction where it improves field robustness.
- Take algorithms from simulation to lab bench to real flight test.
- Work daily with RF hardware and FPGA engineers to bring designs into a fielded radio.
What we're looking for
- Master's or PhD in Electrical Engineering, Signal Processing, or Applied Mathematics.
- 8-12 years designing radio or communication systems, from algorithms to deployed products.
- Hands-on experience with modem or waveform design: modulation, coding, synchronization, equalization.
- Solid grounding in probability, DSP, and information theory; comfortable deriving solutions from first principles.
- Practical awareness of RF hardware and FPGA constraints (latency, precision, real-time processing).
- Clear communicator across RF, FPGA, and software disciplines.
- Fluency in English required.
Nice to have
- Exposure to ECCM, SIGINT, or mesh networking.
- French is a plus.
