Senior FPGA Engineer

Job Title

Senior FPGA Engineer

Role Summary

Design and implement high-performance FPGA digital logic with a firmware/software focus, translating requirements into RTL and low-level software to deliver DSP algorithms, high-speed data protocols, and host integration. Collaborate with cross-functional teams to produce production-ready FPGA systems supporting national-security customers.

Experience Level

Senior — typically 5+ years of hands-on FPGA design and embedded software development (posting lists 5+ years as desired).

Responsibilities

Primary responsibilities include FPGA architecture, IP development, verification, and hardware–software integration for embedded systems.

• Translate software requirements into optimized RTL architecture.
• Design, implement, and test custom IP using VHDL, Verilog, or SystemVerilog.
• Develop low-level C/C++ drivers, Linux kernel modules, and APIs for FPGA–host integration.
• Write comprehensive testbenches (UVM/SystemVerilog) and perform hardware-in-the-loop testing with oscilloscopes and logic analyzers.
• Analyze and optimize placement, routing, clock domains, and timing/power closure.
• Support customers, demos, and presentations; travel up to 25%.
• Work on-site in Dayton, OH with periodic days at Wright-Patterson AFB.

Requirements

Must-have technical skills, security eligibility, and work conditions.

• U.S. citizenship required and ability to obtain or possess a current or recent U.S. Government (DoD) security clearance.
• Proficiency in VHDL, Verilog, or SystemVerilog.
• Strong programming skills in C and C++; scripting experience in Python or Tcl for automation.
• Experience with FPGA toolchains such as AMD/Xilinx Vivado, Intel Quartus, or Microchip Libero.
• Familiarity with High-Level Synthesis (HLS), DSP techniques, and SoC architectures (e.g., ARM‑Cortex embedded in FPGA).
• Knowledge of high-speed interfaces: PCIe, Ethernet (10G/100G), DDR4/DDR5, and AXI streaming.
• Ability to travel for customer support and presentations (up to 25%).
• Physical requirements: prolonged sitting (up to 8 hours/day), ability to lift up to 25 lbs, normal visual and auditory ability for technical work and demos, and mobility between sites and events.

Preferred:

• 5+ years of hands-on FPGA design and embedded software development.
• Domain experience in RF/SDR, defense, automotive (ADAS), high-frequency trading, or data-center systems.

Education Requirements

Bachelor's degree in Computer Science, Electrical Engineering, Computer Engineering, or a related field is specified.
