Senior FPGA Firmware Engineer (Contract)

Senior FPGA Firmware Engineer (Long-term Contract) (Job Location : El Segundo, CA area, about15 miles south-east of Los Angeles) Job Summary Client is seeking a Senior FPGA Firmware Engineer with expertise in digital signal processing, coherent combining of digital signals, high-bandwidth networking, and VITA 49.

Before applying for this role, please read the following information about this opportunity found below.

In this role, you will design, develop, and optimize FPGA-based solutions using Xilinx High-Level Synthesis (HLS) using C++.

Candidate must have an in-depth understanding of (and experience with) FPGA development, and be proficient with FPGA design and performance.

Essential Job Duties and Responsibilities Develop coherent combining and beamforming modules using C++ and Xilinx HLS, ensuring precise phase alignment across multiple channels.

Requirements capturing, design definition & implementation of VHDL detailed designs Implement VITA 49-compliant data packetization for high-speed IF or RF data distribution.

Design and fine-tune DSP blocks (e.g., FFT, filtering, NCO, cross-correlation) to meet stringent real-time and resource utilization requirements.

Work closely with cross-functional teams to ensure signal integrity and minimize latency in large-scale, multi-channel systems.

Use Vivado (or Vitis) for synthesis, simulation, timing closure, and debug.

Create testbenches in C++ / System Verilog / Python to validate functional correctness and phase coherence across all channels.

Provide guidance to junior engineers, reviewing design approaches and ensuring best practices for coherent signal processing.

Collaborate with firmware, software, and hardware teams to define project requirements and deliver high-quality solutions on schedule.

Skills and / or Experience Needed :

• KeySkills : FPGA PROGRAMMING, PYTHON, C++, VIVADO, IDE, LINUX MS or BS in Electrical Engineering, Computer Engineering, or related field, or related engineering field 5+ years of professional experience in FPGA development, specifically in signal processing and high-speed I / O.
