Firmware Engineer

Firmware Design Engineer – Buckinghamshire – Permanent – up to £70,000

We are looking for a motivated and enthusiastic Firmware Design Engineer to join a specialist avionics firmware team developing advanced anti‑jam technology. This is an excellent opportunity for a junior or early‑career engineer looking to take the next step in their firmware career within a highly skilled multidisciplinary engineering environment. If you already have hands‑on VHDL experience and a passion for digital design, we would love to hear from you.

The team develops advanced stand‑alone avionics products and works across the full electronics spectrum — including RF, analogue, digital, power, firmware, DSP, and software. You will gain exposure to real‑world aerospace engineering projects while being supported by experienced engineers who are passionate about mentoring and development.

• Designing, developing, and testing high‑quality FPGA firmware
• Writing and maintaining VHDL code and verification test benches
• Supporting integration, debugging, and validation activities
• Producing technical documentation to support firmware development
• Collaborating closely with systems, hardware, software, and project teams
• Working within a structured, process‑driven engineering environment
• Contributing to planning, estimation, and progress reporting activities

• Work with MATLAB and DSP algorithms
• Support software development activities
• Gain broader exposure to avionics and RF systems engineering

We are particularly interested in candidates who are eager to learn, enjoy solving complex problems, and want to build a long‑term career in firmware and avionics engineering.

• Degree in Electrical, Electronic, Communications, or related Engineering discipline
• Hands‑on experience using VHDL for digital design
• Experience of logic design for DSP
• Understanding of digital logic and FPGA development principles
• Experience writing VHDL test benches and verifying designs using tools such as Model Sim
• Good debugging and problem‑solving skills
• Familiarity with version control systems such as Git
• Strong communication and teamwork skills

If you are looking for a role where you can develop your firmware expertise, work on technically challenging projects, and grow within a supportive engineering team, we would love to hear from you.
