FPGA Engineer (National Security & Critical Systems)

National Security & Critical Systems

Great ideas come from different minds. That's why this organisation brings together engineers, scientists, analysts, and creatives from a wide range of backgrounds - and gives them the trust, tools, and freedom to make a real impact.

What connects everyone is a shared mission: solving meaningful problems and building advanced technical capability that protects what matters most.

As the challenges continue to evolve, so does the technology, with teams working on solutions that will shape tomorrow, not just today.

You'll join a growing and highly trusted supplier within the national security domain, delivering mission-critical solutions that support safety, security, and long-term resilience.

The business has secured long-term programmes of work across a broad technical spectrum, providing genuine stability alongside opportunity for development and growth. It's an environment where engineers can build deep expertise while contributing to work with real national impact.

Projects span leading-edge areas including:

• Digital signal processing and advanced hardware design
• AI / data-driven systems
• Secure platforms, cloud, and modern DevOps practices
• Cyber-focused and software-defined capabilities

As an FPGA Engineer, you'll play a key role in the design and delivery of high-performance hardware solutions. You'll work closely with multidisciplinary teams to develop, integrate, and validate complex systems from concept through to deployment.

Your responsibilities will include:

• FPGA Design & Development Designing, simulating, synthesising, and implementing digital logic using VHDL / Verilog

• DSP Algorithm Implementation Developing and optimising real-time DSP algorithms such as FIR/IIR filters, FFTs, mixers, and I/Q demodulation

• Hardware Interfacing Designing and managing high-speed digital interfaces including ADCs, DACs, and PCIe

• System Integration Collaborating with embedded software, PCB, and systems engineering teams to integrate firmware into deployed solutions

• Debugging & Lab Validation Using oscilloscopes, spectrum analysers, signal generators, and other test equipment to verify and refine designs

• Proven experience in FPGA design and DSP implementation
• Strong practical knowledge of VHDL and/or Verilog
• Experience using MATLAB / Simulink for modelling and validation
• Working knowledge of Embedded C/C++ and/or Python for testing, automation, or processor interaction
• A solid understanding of digital communications theory and RF principles

• Work on projects that genuinely matter, with national-level impact
• Exposure to complex, cutting-edge technology in a secure environment
• Long-term programme stability combined with opportunities to grow and specialise
• Collaborative engineering culture with access to experienced technical leaders

• Based at a secure UK site within an established engineering environment, offering good transport links and access to surrounding countryside
• Due to the nature of the work, applicants must be eligible and willing to undergo Developed Vetting (DV) clearance
