Senior FPGA Design Engineer - RFSoC & DSP Tech

Fairwinds Technologies, LLC; United States; Hybrid; USD 140,000 - 210,000; Full time

Job summary

Fairwinds Technologies, a U.S.-based defense-focused engineering firm, seeks an FPGA Design Engineer to develop programmable logic for Xilinx Zynq UltraScale+ RFSoC/Versal platforms. The role emphasizes RTL design, DSP integration, and collaboration with hardware, DSP, and embedded teams.

The engineer will perform functional simulation, timing analysis, and hardware bring-up on PCB hardware, interfacing with high-speed data converters and embedded processors.

Qualifications

• Bachelor7s degree in Electrical Engineering, Computer Engineering, or related field.
• 10+ years of FPGA design and development.
• Strong proficiency in Verilog and/or VHDL.
• Experience with Xilinx Zynq UltraScale+ RFSoC and Versal devices.
• Experience integrating FPGA designs with high-speed data converters.

Responsibilities

• Design, implement, and verify FPGA logic using Verilog and VHDL within the Xilinx Vivado toolchain for Zynq UltraScale+ RFSoC, MPSoC and Versal devices.
• Develop programmable logic architectures for signal processing, control, and high-speed data movement applications.
• Implement complex DSP algorithms provided by DSP engineers into efficient FPGA fabric designs (filters, FFTs, channelizers, modulators, demodulators, decimation/interpolation, fixed-point optimization).
• Work with embedded software engineers to define and implement PL-PS interfaces, including AXI-Lite, AXI-Stream, DMA, interrupts, and register maps.
• Integrate FPGA designs with embedded processors and heterogeneous compute architectures (e.g., Zynq UltraScale+ MPSoC, RFSoC, Versal ACAP).
• Perform functional simulation, static timing analysis, and resource optimization to meet performance, latency, and power constraints.
• Support FPGA bring-up and debugging on custom PCB hardware using lab tools such as JTAG, Integrated Logic Analyzer (ILA), logic analyzers, and oscilloscopes.
• Participate in system integration and debug efforts spanning FPGA logic, embedded software, DSP algorithms, and hardware.
• Develop test benches, validation strategies, and design documentation, including FPGA design descriptions, interface control documents (ICDs), and SBIR deliverables as required.
• Support prototype-to-production transitions, including ECOs, version control, and configuration management.
