Senior / Principal PCB Design Engineer

Location: Berkshire based, looking for relocating candidates.
Working Pattern: Full-time onsite due to work nature / exposure.
Security Clearance: Must be eligible for Developed Vetting (DV) clearance.

Join a team at the cutting edge of defence and cyber technology, delivering advanced solutions that protect critical information and support mission-critical operations worldwide. Whether you're an experienced PCB Designer looking to step into a Senior role or an established Principal Engineer seeking greater technical influence, this is an opportunity to work on highly secure, technically challenging programmes that make a real-world impact.

Our Cyber Business Unit develops advanced cryptographic and key management solutions, enabling secure communications across tactical and strategic defence environments. You'll play a key role in designing complex PCB solutions for ground-breaking research, development, and production programmes ranging from thousands to millions of pounds in value.

As a Senior or Principal PCB Layout Engineer, you'll be responsible for the design and layout of complex multilayer PCBs (4-20 layers) across defence, aerospace, security, and space applications.

You'll collaborate with multidisciplinary engineering teams to develop high-reliability hardware solutions, supporting projects from concept through to manufacture.

Key responsibilities include:

• Designing complex rigid, semi-rigid, and flex-rigid PCBs incorporating through, buried, and blind vias
• Producing layouts for analogue, RF, digital, power, and high-speed designs
• Ensuring designs meet EMC, signal integrity, security, and TEMPEST requirements
• Working closely with hardware engineers to define routing strategies, impedance control, and design constraints
• Incorporating DFM, DFT, and production test requirements into designs
• Liaising with PCB fabricators and assembly houses to support successful manufacture
• Supporting design reviews and contributing to continuous improvement initiatives
• Estimating design effort and delivering against programme schedules
• At Principal level, contributing to technical proposals, bids, and mentoring less experienced engineers

Essential:

• Degree in Engineering, Science, Mathematics or equivalent industry experience
• Strong background in PCB design, routing, and layout of complex electronic assemblies
• Experience designing multilayer, high-density PCBs
• Expertise with industry-standard PCB design toolsets
• Excellent knowledge of IPC standards and routing best practices
• Proven track record delivering complex designs involving high-speed digital, RF, analogue, and power electronics
• Experience implementing DFM and DFT methodologies

Highly Desirable:

• Signal integrity analysis experience
• Understanding of power distribution and thermal design considerations
• Experience with Gerber and ODB++ data
• Altium Designer and/or PADS expertise
• Schematic capture experience
• Windchill version control knowledge

✅ Up to 10% annual bonus.
✅ £5,000 annual DV allowance once achieved the clearance.
✅ Relocation opportunity available, case by case.
✅ Work on nationally significant cyber and defence programmes.
✅ Exposure to cutting-edge aerospace, space, and security technologies.
✅ Clear progression from Senior to Principal and beyond.

If you're passionate about complex PCB design and want to work on projects that directly support national security and advanced technology development, I'd love to hear from you.
