Senior FPGA Engineer

Job Title

Senior FPGA Engineer

Role Summary

Design and implement FPGA-based solutions for RF and wireless products. Work with a cross-functional hardware and software team to deliver size-, weight-, and power-optimized systems for mission-focused customers.

Experience Level

Senior — typically requires 10+ years of relevant experience.

Responsibilities

Primary duties include digital design and system-level FPGA development for high-speed RF products, verification, and bring-up.

• Design, develop, modify, and evaluate FPGA/ASIC-based electronic components and systems.
• Analyze system requirements and select components based on specifications and reliability.
• Develop HDL implementations and timing/pin constraint strategies; perform synthesis and timing closure.
• Debug complex FPGA designs at system level and during hardware bring-up.
• Implement and validate high-speed interfaces and architectures (e.g., JESD204C, multi-gigabit Ethernet links).
• Integrate FPGA logic with DSP baseband algorithms and peripherals; coordinate software/firmware and hardware integration.
• Execute lab tests, analyze results, and iterate designs to meet performance and form-factor goals.
• Collaborate with cross-functional teams and document design decisions and test results.

Requirements

Must-have technical skills, security, and eligibility requirements.

• 10+ years of relevant FPGA/DSP design experience.
• U.S. Citizenship required; ability to obtain and maintain at least a Secret security clearance and pass a pre-employment drug screen.
• Expertise in HDL coding (VHDL, Verilog, SystemVerilog) and constraint management.
• Proven ability to debug complex FPGA designs in-system and during bring-up.
• Experience implementing and debugging high-speed architectures and transport layers (examples: JESD204C, multi-gigabit Ethernet, VITA-49).
• Strong understanding of communications systems and RF-related concepts (filters, modulation/demodulation, equalization, FEC, AFC, AGC).
• DSP baseband signal processing experience and scheduling of DSP tasks.
• Proficiency programming and scripting for embedded and test environments (Python, C/C++, MATLAB/Simulink, and VHDL-based flows).
• Experience with FPGA peripherals, DMA, and bus interfaces; familiarity with AXI/AXIS is preferred.
• Willingness to travel locally up to 10% and work collaboratively in a small team.

Education Requirements

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

Nice-to-Have

Additional skills that are beneficial but not required.

• Experience with wireless standards (3GPP/LTE, WCDMA, GSM, IEEE 802.11, IEEE 802.15).
• Mixed-signal design understanding (quantization, SFDR, dynamic range) and RF-path compensation techniques.
• Experience bringing up custom hardware with FPGAs or SoCs (Ultrascale+, Zynq 7000, Intel Agilex, etc.).
• Familiarity with softcore processors (Picoblaze, Microblaze, NIOS) and AMBA/AXI buses.
• Advanced simulation experience and knowledge of SystemVerilog classes/packages.
