Job Summary

Join Harmattan AI as an FPGA Radio Engineer responsible for designing and implementing the RF signal-processing pipeline for drone-to-ground communication. Lead end-to-end FPGA development, from architecture to production, collaborating with hardware and embedded software teams in a high-performance, low-latency environment in Paris, France.
Location: Paris
Workplace: Onsite
Employment Type: Full time
Job Function: Communications, PR & Community

Key Responsibilities

  • •Lead the architecture and design of low-latency FPGA-based communications pipelines, spanning the entire signal chain: modulation/demodulation (e.g., OFDM, QAM), FFT, channel coding and decoding (e.g., LDPC, Turbo, Viterbi), synchronization, equalization, and link adaptation.
  • •Own the complete FPGA development cycle, from feasibility assessment and architectural decisions to RTL implementation, simulation, verification, and deployment of robust, production-ready designs.
  • •Conduct system-level link budget analysis, waveform simulations, and performance modeling to validate design choices and assess real-world performance under noise, interference, and multipath conditions.
  • •Design and maintain comprehensive testbenches and validation frameworks for complex DSP pipelines, including hardware-in-the-loop testing with real RF front-ends.
  • •Work closely with RF hardware engineers to ensure seamless integration between FPGA designs and the analog front-end (ADC/DAC interfaces, AGC, frequency planning).
  • •Evaluate and select FPGA platforms, IP cores, and toolchains based on project constraints such as latency, throughput, power consumption, and long-term scalability.
  • •Define and document clear, well-specified interfaces between the FPGA, embedded software, and hardware layers.

Key Requirements

  • •Master’s degree (or equivalent) in Electrical Engineering, Signal Processing, Telecommunications, or a related field.
  • •Over 5 years of hands-on FPGA development experience, including end-to-end ownership using VHDL and/or Verilog/SystemVerilog.
  • •Strong foundation in digital communications and signal processing, grounded in first principles.
  • •Solid understanding of the RF signal chain and its impact on digital design, including ADC/DAC interfaces, IQ imbalance, phase noise, dynamic range, sampling, and filtering.
  • •Experience working in low-latency, real-time environments with strict resource constraints, making informed trade-offs among latency, precision, power consumption, and logic utilization.
