About the role

FPGA Radio Engineer responsible for designing and implementing the communications link between drones and ground stations, owning the RF signal-processing pipeline end-to-end from architecture to production-ready deployment in a fast-paced, autonomous setting.

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.

Qualifications

  • 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.
  • Familiar with link budget analysis, waveform design, and system-level simulation tools.
  • Comfortable working autonomously, taking full technical ownership, and communicating effectively across hardware, software, and systems teams.
  • Fully dedicated to Harmattan AI’s mission, vision, and ambitious growth objectives, always prepared to go the extra mile to ensure operational excellence.
