Job description

Principal Electronics Engineer

Date: 20 Jun 2026
Location: High Wycombe, GB
Job Function: Technical
Business Unit: NanoAnalysis

Materials Analysis is an Oxford Instruments Business Unit that manages our Electron Microscopy and Mechanical Microscopy products, Atomic Force Microscopes, Raman Microscopes and Benchtop NMR Products. We are part of the wider Oxford Instruments Group that also includes Andor Technology, Plasma Technology and X-Ray Technology. With a sixty-year history, and fourteen Queen’s Awards for Enterprise, our world-class products and technologies are helping our customers to address the greatest challenges of the 21st century.

At Oxford Instruments, we enable the world’s leading scientists and engineers to explore materials at the nanoscale. Within our NanoAnalysis business, our systems power electron microscopy techniques such as SEM and TEM—unlocking elemental and structural insights across industries from semiconductor development to clean energy.

Opportunity

Now, we’re looking for a Principal Electronics Engineer (analgoue) to help architect and design the next generation of high-performance analytical instrumentation.

You’ll play a key role in developing sophisticated electronics that sit at the heart of our electron microscopy solutions—where precision, signal integrity, and low-noise design are mission-critical.

Working in a multidisciplinary R&D team, you’ll design, test, and deliver advanced electronics systems that directly impact how our customers visualise and analyse the microscopic world.

You will also be instrumental in developing the skills and competencies within the electronics team, helping to mentor more junior engineers to fulfil their potential.
