Senior FPGA Engineer

Job Title

Senior FPGA Engineer

Role Summary

The Senior FPGA Engineer will architect, design, implement, and verify FPGA-based digital signal processing solutions for tactical SIGINT/EW systems. Work focuses on Xilinx devices to support wideband RF signal collection, software-defined radio (SDR) functionality, and data communication with peripherals.

The role requires close collaboration with hardware, firmware, and software teams to define system specifications and deliver production-ready FPGA designs.

Experience Level

Senior — typically 5+ years of related FPGA and RF/SDR development experience.

Responsibilities

Primary responsibilities include system architecture, FPGA algorithm implementation, and integration/verification of FPGA designs in RF systems.

• Architect and implement FPGA solutions for wideband RF signal collection and processing systems.
• Design and implement FPGA algorithms for SDR capabilities (e.g., peak detection, digital filters, modulation/demodulation, CORDIC, FFT).
• Define interfaces and data communication between FPGAs and peripheral devices.
• Document detailed designs and system specifications.
• Integrate, troubleshoot, and verify FPGA designs using lab test equipment.
• Collaborate with hardware and software teams to meet system-level requirements.

Requirements

Must-have technical skills, clearance, and practical experience required for the role.

• 5+ years of relevant FPGA development and DSP experience.
• Proven experience implementing SDR capabilities on FPGAs (examples: peak detectors, filters, modulation/demodulation, CORDIC, FFT).
• Experience with Xilinx Ultrascale and/or Versal families, preferably within an RFSoC architecture.
• VHDL design entry, constraints, simulation, and synthesis using Xilinx Vivado.
• Experience debugging FPGA-based systems with oscilloscopes, spectrum/network analyzers, and signal generators.
• Experience with RF transceiver design across various frequency ranges.
• Active Top Secret clearance (U.S. citizenship required) with ability to obtain SCI.

Nice-to-have:

• Experience interfacing FPGAs to ARM processors or microcontrollers.
• C/C++ experience for software or embedded firmware.
• Experience with Embedded Linux on SBCs or PetaLinux on Xilinx platforms.
• MATLAB experience, especially HDL Coder or Embedded Coder.
• Experience with Intel/Altera FPGAs and Quartus toolchain.

Education Requirements

Bachelor's degree or equivalent practical experience is stated; no specific field of study was specified. The posting explicitly allows equivalent experience in lieu of a degree.
