Test Development Engineer

About the Company

Poro Technologies Ltd (Porotech), the Gallium Nitride (GaN) material technology developer, focuses on the development of high performance and energy efficient wide-bandgap compound GaN semiconductors. Its unique production process allows the controlled creation of a new class of nanostructured GaN semiconductor materials, called PoroGaNTM, engineered to deliver new materials properties and functionalities.

GaN is the silicon of the future, as it has many more interesting properties, including energy efficiency, than any other semiconductor materials. We can control the porosification process to vary the GaN nanostructures and hence engineer a wide range of material properties, such as optical, mechanical, thermal and electrical.

In conjunction with its partner and foundry network, Porotech is commercialising its PoroGaNTM semiconductor device solutions, offering an entirely new platform for MicroLED devices to be built upon and delivering transformative properties in a single, fully scalable step.

The technology is revolutionising the next-generation Micro-LED display industry by enabling all three (red, green and blue) pixel colours to be realised on a single InGaN materials system – an important world-first for mass market adoption.

About the role

We are looking for a Test Development Engineer to join our product development team based in Cambridge, UK. You will be part of a team that handle, integrate, design and test optoelectronic materials & devices. The role will be hands on supporting R&D activity and you will contribute to development of measurement and analysis techniques.

If you have this mindset and believe you could bring your unique skills and ideas to the company, we’d love to meet you and find out if our challenge is just as exciting to you as it is to us.

What you will do

  • Effective running of our electrical and optical testing processes and protocols
  • Maintain day-to-day activities in the characterisation lab
  • Analyse and report test results to the wider team
  • Contribute to continuous improvement and development of new characterisation techniques
  • Maintain test records and documentation

Skills/Experience required:

  • BSc in Physics, materials science, electrical engineering, chemical engineering or a similar discipline, or two years testing or process engineer experience in semiconductors
  • Experience of working in a commercial laboratory or manufacturing environment
  • Experience of manual handling under magnification
  • Data analysis & text-based coding skills (e.g. Python, JMP, Excel macro, C, Matlab)
  • Ability to work independently to meet agreed objectives and timelines
  • Observant and excellent attention-to-detail

Advantageous Skills:

  • Hands-on experience with optical microscopy, electroluminescence and photoluminescence spectroscopy
  • Hands-on experience with characterisation of electronic devices (e.g. IV, CV with probe stations and SMU’s)
  • Knowledge and understanding of wide-bandgap semiconductor materials, processing, and characterisation technologies
  • Hands on cleanroom experience
  • Experience with handling and disposing of chemicals


At Porotech, we would like you to enjoy the success of the company to emerge from the UK and lead the world’s III-nitride semiconductor development, which you will be helping to build and be part of. It is an ideal time to join with a business with unique technology and products that are ready to be delivered and going to change the market.

Competitive salary dependent on experience. The ideal candidate could also benefit from a generous company share option program as well as health insurance, dental insurance and pension plan. If you are interested in helping us change the world, send your CV with a cover letter to careers@porotech.co.uk. We look forward to making your acquaintance.
