Signal Processing Engineer (Radio)

The role

You will own the algorithmic core of a drone-to-ground radio link. You will design waveforms, anti-jam logic, and signal intelligence to ensure reliable links in contested environments.

What you will do

• Design modulation, coding, and equalization schemes for a radio link.
• Build algorithms to keep the radio link alive under active jamming.
• Detect and characterize other radio emitters in the operating environment.
• Optimize protocols so multiple radio units share the airwaves without collision.
• Apply machine learning to jamming detection and channel prediction.
• Take algorithms from simulation to lab bench to real flight test.
• Work with RF hardware and FPGA engineers to bring designs into a fielded radio.

Required qualifications

• 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.
• 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
