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 using Xilinx devices. The role collaborates with hardware and software teams to define system specifications, document designs, and deliver production-ready FPGA implementations.

Experience Level

Senior — typically requires 5+ years of relevant FPGA and RF / software-defined radio experience.

Responsibilities

Primary responsibilities include:

• Architect and implement FPGA solutions for wideband RF signal collection and processing systems.
• Design and implement FPGA algorithms for signal detection and processing (e.g., peak detectors, digital filters, modulation/demodulation, CORDIC, FFT).
• Integrate FPGA logic with RF transceivers and peripheral devices, and support data communication interfaces.
• Work with hardware and software teams to define system-level specifications and architectures.
• Document detailed designs, perform simulation and synthesis, and execute verification and troubleshooting activities.
• Use laboratory test equipment (oscilloscopes, spectrum/network analyzers, signal generators) to debug and validate systems.
• Support deployment of FPGA designs on tactical SIGINT/EW platforms and provide sustainment as needed.

Requirements

Key qualifications and security/operational requirements.

Must-have:

• 5+ years of related FPGA design experience working on DSP and RF signal processing applications.
• Experience implementing software-defined radio capabilities on FPGAs (peak detectors, filters, modulation/demodulation, CORDIC, FFT).
• Experience with Xilinx Ultrascale and/or Versal FPGA families, including RFSoC architectures.
• VHDL design entry, constraints, simulation, and synthesis experience using Xilinx Vivado.
• Proven ability to debug FPGA-based systems using oscilloscopes, spectrum analyzers, network analyzers, and signal generators.
• Experience with RF transceiver design across multiple frequency ranges.
• Active Top Secret clearance (U.S. citizenship required) and ability to obtain SCI access.
• Willingness to travel up to 10% (local travel).

Nice-to-have:

• Experience interfacing FPGAs to ARM processors or microcontrollers.
• C/C++ experience in software or embedded firmware environments.
• Experience with Embedded Linux on SBCs or PetaLinux on Xilinx platforms.
• MATLAB experience, especially HDL Coder or Embedded Coder.
• Experience with Altera (Intel) FPGAs and Quartus/Signal Tap toolchains.

Education Requirements

Bachelor's degree or equivalent practical experience required. The posting permits equivalent experience in place of a degree; specific fields of study were not specified.
