Location: High Wycombe, Buckinghamshire
Salary: Up to £70,000
The Opportunity
KO2's client is a specialist engineering business operating in a highly regulated and technically demanding sector. They design, manufacture, and deliver electronic systems where performance and reliability are paramount, working on programmes that have genuine real-world impact. This is a rare opening for a Principal Electronics Engineer to join a small, expert team working on some of the most technically challenging and commercially significant projects in their field.
Why This Role Is Worth Your Attention
This is not a box-ticking electronics role. You will be working on complex, high-integrity systems that require serious analogue design capability and the confidence to take technical ownership from concept through to delivery. The team is experienced, the work is meaningful, and your contribution will be visible. Specifically, you will be involved in the design and development of electronic systems used in weapons interface applications for the UK defence sector, requiring SC security clearance. Few roles offer this level of technical depth alongside the chance to act as a genuine authority within the engineering function.
The working week is 4.5 days (Friday afternoon off), with an initial site-based period that reduces over time as trust is established. The role is based at the client's Loudwater facility, which is conveniently commutable from High Wycombe and the surrounding area.
