Electronics Systems Engineer III in London

Everfox, formerly Forcepoint Federal, has been defending the world’s most critical data and networks against complex cyber threats for more than 25 years. As trailblazers in defense-grade, high assurance cyber security, we have been leading the way in developing and delivering innovative cyber security technology. We protect data wherever it resides.

Our unwavering dedication and commitment to our customers and the critical missions they serve are what set us apart. We are dynamic, vigilant, and proactive in everything we do. Our suite of cross domain, threat protection and insider risk solutions empower governments and enterprise organizations to use data safely - where and however their people need it.

What we're looking for:

You're a hands-on engineer who's comfortable being handed a problem and running with it. You've delivered complex PCB designs before and you know the difference between a design that works on the bench and one that survives production and the field. You'll own the full design lifecycle for sophisticated electronic hardware - from requirements through to production - working largely independently and making real technical decisions that shape the products we ship.

That means:

• Designing hardware that has to work: PCBs featuring high-speed digital, FPGA platforms, switch-mode power, and mixed-signal circuitry, laid out in Altium to production-ready standard.
• Solving hard problems: Independently diagnosing issues using structured root-cause analysis and the full range of lab equipment, from oscilloscopes to spectrum analyzers.
• Thinking at system level: Understanding how your design choices ripple through EMC behaviour, thermal performance, firmware integration, and long-term reliability.
• Taking it all the way: From compliance and certification through to manufacturing handover, you own the outcome.
• Working with top talent: Collaborating directly with firmware, systems, and mechanical engineers to make sure the full product hangs together.
• Raising the bar: Supporting and mentoring junior engineers, contributing to design reviews, and actively improving how the team works.

This is not a role where you execute someone else's design decisions. You'll be the person making them.

You'll need:

• A Master's degree in Electronic Engineering or similar.
• A proven track record of independently delivering multi-layer PCB designs (high-speed digital, power, mixed-signal).
• Solid experience with Altium Designer - schematic capture through to layout.
• Confidence diagnosing hardware with real lab equipment and structured fault-finding techniques.
• Experience taking designs through the full lifecycle, including HW/FW integration and manufacturing transition.
• The judgement to make well-reasoned trade-off decisions and explain your rationale clearly.

Bonus points for:

• Python or C scripting for test automation or data analysis.
• FPGA development experience (VHDL).
• Familiarity with EMC compliance standards or reliability methods (FMEA, derating).

A reasonable estimate of the base salary range for this role is: £56,800.00 GBP. The actual salary offered may vary within the range based on a candidate's unique experience, locale, and business needs. In addition to a base salary and bonus plans, Everfox offers a generous benefits package including flexible PTO, a 401k match, and contribution to healthcare coverages.
