Senior/Principal Reliability Engineer (Power Devices)

Team – R&D Engineering

Location – Cambridge

Contract – Permanent (Full time or part time)

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.

Main Responsibilities

  • Design and execute device reliability characterisation experiments of GaN power ICs
  • Development of characterisation strategies and test planning (DOE)
  • Development of GaN device reliability models
  • Develop new test methods for GaN-IC reliability
  • Write reliability-specific application notes and white papers
  • Lead reliability aspects of Technology R&D and Product R&D projects
  • Design and run customer-specific tests
  • Lead TCAD and multi-physics simulation projects for reliability insight
  • Liaise with electrical engineers for the development of reliability characterisation systems

Where to Advertise Semiconductor Jobs in the UK (2026 Guide)

Advertising semiconductor jobs in the UK requires a fundamentally different approach to most technical hiring. The candidate pool is one of the smallest and most specialised in any engineering discipline — spanning IC design engineers, process engineers, fab technicians, EDA tool developers, compound semiconductor physicists and power electronics specialists. General job boards are largely ineffective for semiconductor hiring. The community is tight-knit, highly academic in its roots and concentrated around a small number of university groups, fab facilities and design centres. Specialist boards, academic channels and direct community engagement are the primary sourcing strategies that work. This guide, published by SemiconductorJobs.co.uk, covers where to advertise semiconductor roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

New Semiconductor Employers to Watch in 2026: UK and International Companies Transforming Chip Careers

The semiconductor industry is entering a new era of investment, geopolitical significance, and technological innovation. As advanced chips power everything from artificial intelligence and edge computing to autonomous vehicles and 5G infrastructure, demand for skilled professionals across design, verification, fabrication, and test engineering continues to rise. For professionals exploring opportunities on www.SemiconductorJobs.co.uk , understanding which employers are scaling, raising funds, winning contracts, or establishing UK operations is critical. This article highlights the new semiconductor employers to watch in 2026, including UK innovators, major international players expanding locally, and emerging firms driving next‑generation semiconductor technologies.

How Many Semiconductor Tools Do You Need to Know to Get a Semiconductor Job?

If you’re pursuing a career in the semiconductor industry, it can feel like you’re expected to master an endless list of tools, software packages and lab equipment before you even submit a CV. One job advert wants experience with TCAD and process simulation, another mentions SPICE and yield tools, while yet another asks for test automation platforms, yield analysis software, hardware description languages, EDA suites and hundreds of others. With so many technical names thrown around, it’s easy to fall into “tool anxiety” — the feeling that you’re behind because you don’t know every piece of software, every lab instrument and every process control suite. Here’s the honest truth most semiconductor hiring managers won’t say out loud: 👉 They don’t hire you because you know every tool — they hire you because you can use the right tools to solve real engineering problems and explain your reasoning clearly. Tools matter, absolutely. But they exist to help you deliver measurable results — not to be collected like badges. So how many semiconductor tools do you actually need to know to get a job? The answer is a lot fewer than you might think — and far more focused on core capabilities than a long checklist. This guide breaks down what employers really value, which tools are essential, which are role-specific, and how to focus your learning so you are confident and credible.
