Senior FPGA Engineer

Job Title

Senior FPGA Engineer

Role Summary

Design and develop FPGA-based hardware and firmware for RF and wireless products, emphasizing size, weight, power, and packaging constraints. Work with cross-functional teams to deliver fieldable solutions on aggressive schedules.

Experience Level

Senior — 10+ years of relevant experience.

Responsibilities

Core responsibilities include hardware and FPGA design, system integration, verification, and debugging for RF/wireless products.

• Architect, implement, and verify FPGA designs and high-speed interfaces for RF products.
• Develop and maintain HDL code (VHDL, Verilog, SystemVerilog) and manage timing/pin constraints.
• Integrate FPGA designs with DSP algorithms and peripherals; support algorithm-to-hardware implementation.
• Bring up and debug hardware and firmware in system-level test and lab environments.
• Implement and validate high-speed transports and protocols (e.g., JESD204C, multi-Gbps Ethernet, VITA-49).
• Perform component selection, experimental tests, and analyze results to meet reliability and performance targets.
• Collaborate with mechanical, RF, and software engineers; produce technical documentation and reports.
• Support local travel (up to 10%) for integration and testing activities.

Requirements

Must-have technical skills, work-eligibility, and security requirements. Preferred skills listed separately.

• In-depth HDL experience: VHDL, Verilog, SystemVerilog.
• Experience managing pin and timing constraints and debugging complex FPGA designs in system.
• Experience with high-speed architectures and protocols such as JESD204C and multi-Gbps Ethernet (2.5G–100G).
• Knowledge of communications systems and RF concepts: modulation/demodulation, channel equalization/estimation, FEC, AFC, AGC.
• DSP baseband processing and peripheral programming; DSP/FPGA co-design experience.
• Proficiency with Python, C/C++, and MATLAB/Simulink for algorithm development and integration.
• Demonstrated ability to bring up custom hardware with FPGAs/SoCs and debug system-level issues.
• U.S. Citizenship required and ability to obtain/maintain at least a Secret security clearance.
• Self-starter with strong communication and teamwork skills.

• Experience with wireless standards (3GPP LTE, WCDMA, GSM; IEEE 802.11; IEEE 802.15).
• Mixed-signal design experience and understanding of quantization, SFDR, dynamic range, and RF path imperfections.
• Experience with SoC families (Ultrascale+, Zynq 7000, Intel Agilex) and softcore processors (MicroBlaze, Picoblaze, NIOS).
• Experience with DMA/AMBA buses (AXI/AXIS, ACP) and SoC integration.
• Familiarity with SystemVerilog classes/packages and advanced simulation methodologies.

Education Requirements

Bachelor's degree in Electrical Engineering or a closely related technical field (BS in EE or similar) is required. U.S. Citizenship is required; candidates must be willing and able to obtain at least a Secret security clearance.
