Job summary

CBSbutler in London is seeking an Electronics Systems Engineer to take complex hardware from concept through to production in a hands-on, hybrid London role.

You will design and lay out high-speed PCBs, work with DDR/PCIe/Ethernet/USB interfaces, develop FPGA-based hardware, and use Python for automation, testing and validation alongside software, systems and manufacturing engineers. This is a technically challenging, end-to-end design position.

Qualifications

• Proven high-speed PCB design and layout experience.
• Experience with high-speed interfaces (DDR, PCIe, Ethernet, USB, SERDES, LVDS).
• FPGA development experience and hardware test/debug aptitude.
• Hands-on, cross-disciplinary hardware engineer capable of end-to-end design.

Responsibilities

• Design and develop high-speed PCBs from concept to bring-up.
• Work with high-speed digital electronics and complex interfaces.
• Develop and integrate FPGA-based hardware.
• Lead simulation, prototyping, testing and troubleshooting.
• Use Python for automation, testing and design validation.
• Collaborate with software, systems and manufacturing engineers.

Job description

London | Hybrid

If you’re an Electronics Engineer who enjoys taking complex hardware from concept through to a working, tested product, this is a role worth looking at.

I’m supporting a global information security technology business developing high-assurance products used by government and defence organisations to securely protect and share highly sensitive information. Due to large scale growth they are looking for 3 x Electronics Systems Engineers to join their London engineering team.

The big thing they need? Genuine hands‑on experience designing and laying out high‑speed PCBs.

You’ll be working on technically challenging hardware where performance, reliability and security genuinely matter, getting involved across the development lifecycle rather than being restricted to one small part of the process.

What will you be doing?

• Designing and developing high-speed PCBs, including schematic design and layout
• Working with high-speed digital electronics and complex interfaces
• Developing and integrating FPGA-based hardware
• Taking designs through simulation, prototype, board bring-up, test and troubleshooting
• Using Python for automation, testing and design validation
• Working across both digital and analogue electronics
• Collaborating with software, systems and manufacturing engineers
• Supporting products through integration and into manufacture

What are we looking for?

The key requirement is proven high-speed PCB design and layout experience.

We’d particularly like to speak with engineers who have worked with areas such as DDR, PCIe, Ethernet, USB, SERDES, LVDS or other high-speed interfaces, with an understanding of areas such as signal integrity, controlled impedance, differential pairs and length matching.

Experience with FPGA development, Python and hardware test/debug would make you particularly relevant.

You don't necessarily need a defence or cybersecurity background. Engineers coming from aerospace, communications, semiconductor, instrumentation, high-performance computing or other complex electronics environments could be equally interesting.

This isn't a management role. It's an opportunity for an engineer who wants to remain hands‑on technically, work on sophisticated hardware and continue developing their expertise.

Package

• Annual bonus
• Private Medical Insurance
• Income protection
• Competitive annual leave
• Health cash plan
