About CGD

Making Sustainable Power Electronics Possible

A spin-out of the Cambridge University, Cambridge GaN Devices (CGD) is a fabless semiconductor company that develops a range of energy-efficient GaN-based power devices to make greener electronics possible

The global power semiconductor market is expected to exceed $50BN. In addition to the multi-million seed fund and Series A and now B private investments, CGD has so far successfully secured four projects funded by iUK, BEIS and EU (Penta). The technical and commercial expertise of the CGD team combined with an extensive track record in the power electronics market has been fundamental in early market adoption of our proprietary technology.

Bringing Innovation into Everyday Life

The environmental need for solutions to resolve the world’s most significant challenges (energy consumption and CO2 emissions) inspires us to contribute to society by preserving nature with energy-efficient power solutions.

With a mindset on pushing the limits of semiconductor (GaN) properties and an outstanding team of worldwide experts leveraging knowledge, IP, and decades of research, we demonstrate technological advancement by developing green solutions for everyday electronics, respecting our planet’s natural resources, and creating a more sustainable future for the generations to come.

Why Work for CGD

We Champion Commitment, Celebrate Empowerment, and Reward the Brave.

We are interested in change-makers with a passion for power semiconductors who are willing to explore unconventional ways to meet the company’s green agenda.

At CGD, we pride ourselves on putting empowerment and commitment at the core of our company culture. We offer a relaxed yet productive working environment where everybody is valued and respected and becomes part of commercial success while experiencing professional growth.

If your heart beats for innovation, challenge, and growth, and if the prospect of joining a friendly and game-changing company is for you, we want to hear from you.

The Opportunity

CGD is looking for a Senior/Principal Reliability Engineer to join our growing engineering team. The Senior/Principal Reliability Engineer will primarily be responsible for all reliability aspects of CGDs GaN power devices and ICs. This includes designing the reliability experiments as well as analysis and developing reliability models. The Senior/Principal Reliability Engineer will also develop new electrical reliability tests, specifically for GaN ICs, and gain insight into their reliability by collaborating with TCAD and multi-physics simulation engineers. In this role, the successful applicant will be able to use and develop new knowledge on power devices, GaN and reliability testing, which is at the forefront of GaN device R&D.

Ultimately, the Senior/Principal Reliability Engineer will be responsible for producing confident reliability data and information for CGD and our customers.

This role is based at the company’s office and lab in Cambridge, UK, although it is expected that some travel will be required from time to time.

This role could be full time or ‘family-friendly’ part time.
