Company Overview

We are growing our Electronic Warfare Operations Support Group (EWOS), a team of over 60 specialists from a wide range of backgrounds. Our engineers, scientists, and ex-military personnel work together to help our customers achieve their true operational potential and keep their people and platforms safe. As part of this growth, MASS is looking for a Principal FPGA Engineer to join our modelling team in Lincoln, supporting the delivery of technical excellence on a large, cutting-edge System-of-Systems programme.

Role Description

This is a collaborative, hands-on role, suited to someone with strong experience in FPGA design and a passion for developing signal processing systems for complex, real-world challenges. You will 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. The invaluable experience you will bring will help us achieve more.

Key Responsibilities

Define and implement 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

Collaborate with systems, RF, embedded software, and verification engineers to ensure end-to-end performance and compliance

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 low-level C software for FPGA bring-up, test, and integration

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

Drive design verification, unit testing, and documentation to ensure high-reliability deployment

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

Essential Experience

Proven track record in delivering FPGA designs for real-time, high-speed, or RF-centric systems

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

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

Expertise with Vivado, Quartus, constraint management, simulation, and timing closure for multi-clock, high-throughput designs

Desirable Experience

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

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)

Exposure to real-time signal playback/recording systems, or hardware-in-the-loop (HIL) test environments

Knowledge of bitstream encryption, secure boot, or anti-tamper features in FPGA-based systems

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

Additional Information

Wellbeing is at the core of our culture, allowing employees to flourish and achieve their full potential. Our people are important to us, and we take pride in our wellbeing programmes and policies that support individuals, including mental health first aiders and readily available support through our extensive employee assistance programme.

Non-negotiables

Due to the highly secure nature of the projects you will be involved with, you must be:

A UK National and eligible to work in the UK

Eligible to obtain and maintain a UK Government SC-level security clearance
