Senior FPGA Engineer

Job Title

Senior FPGA Engineer

Role Summary

Design and implement FPGA solutions for CACI's wireless and RF products. Work on system-level FPGA/DSP architectures, collaborate with hardware, firmware, and systems engineers, and support product bring-up and integration. Role may require limited travel (up to 10%).

Experience Level

Senior-level. The posting requests 10+ years of relevant FPGA, DSP, and communications systems experience.

Responsibilities

Primary responsibilities include designing, implementing, and validating FPGA-based signal processing and communications subsystems and supporting system integration.

• Architect, code, and verify FPGA firmware for DSP and RF applications.
• Develop pin and timing constraints; manage implementation and timing closure.
• Debug complex FPGA designs at the system level and during hardware bring-up.
• Implement and validate high-speed interfaces (e.g., JESD204C, 2.5G–100G Ethernet).
• Integrate transport layers such as VITA-49 into FPGA systems.
• Collaborate with cross-functional teams on embedded software, hardware, and test activities.
• Support test plans, experimental verification, and evaluation of component/board performance.

Requirements

Must-have qualifications and skills.

Must-have:

• 10+ years of relevant FPGA/DSP/communications experience.
• U.S. Citizenship and ability to obtain and maintain at least a Secret security clearance; willing to pass pre-employment drug screen.
• In-depth HDL coding experience in VHDL, Verilog, and SystemVerilog.
• Experience managing pin and timing constraints and achieving timing closure.
• Proven ability to debug complex FPGA designs in system-level environments.
• Experience with high-speed architectures and interfaces (JESD204C, multi-gigabit Ethernet up to 100G).
• Knowledge of communications systems and algorithms: modulation/demodulation, channel estimation/equalization, FEC, AGC/AFC, RF filters.
• DSP baseband processing and peripheral programming; experience programming DSPs and FPGAs using Python, C/C++, and MATLAB/Simulink.

Nice-to-have:

• Experience implementing wireless standards (3GPP LTE/WCDMA, IEEE 802.11, IEEE 802.15).
• Mixed-signal experience: quantization, dynamic range (SFDR), and baseband equivalent modeling.
• Experience with SoCs (Ultrascale+, Zynq 7000, Agilex) and softcore processors (Picoblaze, MicroBlaze, NIOS).
• Experience with DMA and AMBA/AXI buses and simulation using SystemVerilog classes/packages.

Education Requirements

Bachelor of Science (BS) in Electrical Engineering or a closely related field is specified.
