Senior FPGA Engineer

As part of this growth, MASS is looking for a Senior FPGA Engineer to join our modelling team in North Hykeham, Lincoln, supporting team development and the delivery of technical excellence.

This is a collaborative hands-on role suited to someone with considerable experience in FPGA design and a passion for developing signal processing systems for complex, real-world challenges.

You'll work closely with cross functional teams, acting as a technical lead in the design and delivery of systems that include RF signal chains, high-speed digital interfaces, and real-time DSP. Your work will influence key architectural decisions, address integration challenges, and help shape the development of reconfigurable hardware platforms for use in mission-critical environments.

Key responsibilities:

Lead the design, implementation and verification of advanced FPGA architectures for RF signal processing, high-throughput data handling, and real-time logic.

Develop for AMD/Xilinx RFSoCs (e.g. Zynq UltraScale+) and Intel FPGAs (e.g. Agilex), including integration with high-speed ADCs/DACs.

Support test and lab evaluation using signal generators, spectrum analysers, and oscilloscopes.

Lead or contribute to the implementation of designs using VHDL, SystemVerilog, and MATLAB/Simulink HDL Coder.

Develop C/C++ software for deployment to embedded systems

Use industry-standard tools such as Vivado, Quartus, and ModelSim for simulation, synthesis, and implementation

Drive design verification, unit testing, documentation and best practice in FPGA development

Act as a technical expert in reviews, solution development, and internal consultation across teams

Mentor junior engineers and provide technical leadership across FPGA projects

Engage with stakeholders to capture requirements and ensure technical solutions align with project and business requirements

• Proven experience in DSP algorithm development on FPGA architectures to deliver designs for real-time, high-speed, or RF-centric systems

• Experience with MATLAB/Simulink and HDL Coder for algorithm-to-hardware workflows

• Proven ability to develop and deploy on Xilinx RFSoC (e.g. Zynq UltraScale+) and/or Intel Agilex/Stratix platforms

• Experience of line management of junior team members

• Experience using laboratory equipment for digital hardware/firmware design testing (Oscilloscopes, signal generators and logic analysers)

Desirable Experience

• Experience working with embedded Linux, bare-metal C drivers, or FPGA-based system integration

• Proficiency in VHDL, SystemVerilog, and embedded C for FPGA-host integration, control, and testing

• Familiarity with AXI interfaces, memory interfaces, JESD204B/C, or high-speed ADC/DAC integration

• Experience designing streaming architectures using AXI4-Stream, DMA, and memory buffers (e.g. BRAM, URAM)

• Knowledge of data framing, tagging, and high-throughput IQ data handling

• Experience working with synthetic electromagnetic environments and their associated software and hardware requirements and limitations

• Familiarity with Atlassian products (Jira/Bitbucket) for project and task management and collaborative development

• Experience with C/C++ for embedded systems

• Knowledge of EW systems and concepts, including radar systems
