A funded PhD opportunity is available at the University of Bristol in the area of advanced power electronics using wide-bandgap (WBG) semiconductor devices, with a particular focus on silicon carbide (SiC) and gallium nitride (GaN) technologies. The project will investigate next-generation high-efficiency, high-power-density power conversion systems for applications including aerospace, electric transportation, renewable energy, and advanced industrial systems.

Wide-bandgap devices offer significant advantages over conventional silicon power semiconductors, including faster switching speeds, higher operating temperatures, and reduced power losses. However, achieving their full performance potential requires major advances in gate driving, high-bandwidth sensing, packaging, electromagnetic compatibility, and long-term reliability assessment. The PhD research will therefore focus on the development of advanced active gate driving techniques and ultra-fast sensing solutions capable of enabling stable and efficient operation of high-speed SiC and GaN converters under demanding operating conditions.

The project will also investigate reliability and degradation mechanisms in WBG devices, including the effects of high switching speeds, thermal cycling, parasitic interactions, and extreme operating environments. Experimental characterisation, accelerated lifetime testing, and physics-informed modelling will be used to evaluate device behaviour and improve converter robustness and reliability.

The student will gain experience in the design, modelling, fabrication, and experimental testing of state-of-the-art power electronic systems using advanced laboratory facilities and industrially relevant hardware platforms. Research activities may include high-frequency converter design, PCB and package optimisation, EMI-aware design, thermal management, digital control, and data-driven analysis methods.

This PhD provides an excellent opportunity to contribute to cutting-edge research in wide-bandgap power electronics while developing expertise highly sought after in academia, aerospace, automotive, renewable energy, and semiconductor industries.

PhD Candidates must hold a minimum of an upper Second-Class UK Honours degree or international equivalent in a relevant engineering or science discipline. Applicants must hold/achieve a minimum of a merit at master’s degree level (or international equivalent) in a science, mathematics or engineering discipline. Applicants without a master's qualification may be considered on an exceptional basis, provided they hold a first-class undergraduate degree. Please note, acceptance will also depend on evidence of readiness to pursue a research degree.

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

Where to advertise semiconductor jobs UK in 2026: the specialist boards, academic channels and community routes that actually reach IC, fab and EDA talent. 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.

Semiconductor Jobs UK 2026: What to Expect Over the Next 3 Years

Semiconductor Jobs UK 2026: roles, salaries and the hiring trends shaping UK semiconductor recruitment over the next three years — what to expect now. Semiconductors are the foundational technology of the modern world. Every smartphone, electric vehicle, data centre, medical device, satellite, and AI accelerator depends on them. And yet for much of the past decade, the strategic importance of semiconductor design and manufacturing was something that governments, investors, and employers took largely for granted — until supply chain crises, geopolitical tensions, and the insatiable compute demands of artificial intelligence made the vulnerability of global semiconductor supply chains impossible to ignore. The response has been significant and sustained. The UK's National Semiconductor Strategy, the US CHIPS Act, the EU Chips Act, and parallel investment programmes across Japan, South Korea, and Taiwan have collectively committed hundreds of billions of pounds to semiconductor research, design, and manufacturing capability. In the UK specifically, that investment is beginning to translate into real hiring — across compound semiconductor manufacturing, chip design, semiconductor equipment, advanced packaging, and the growing ecosystem of fabless design companies that are choosing Britain as their base. For job seekers, the semiconductor jobs market of 2026 represents an opportunity that is more commercially urgent, more geographically distributed, and more technically diverse than at any previous point in the sector's UK history. The roles being created span the full semiconductor value chain — from fundamental materials research and process engineering through chip design, verification, and the software that makes silicon useful. The candidates who will thrive over the next three years are those who understand where that value chain is being built, which technical areas are attracting the most investment, and how to position their skills at the intersection of the sector's greatest needs. This article breaks down what the UK semiconductor jobs market is likely to look like through to 2028 — covering the titles emerging right now, the technologies driving employer demand, the skills that will matter most, and how to position your career at the leading edge of one of the most strategically important technology sectors in the UK economy.

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

New Semiconductor Employers to Watch in 2026: a UK and international shortlist of chip companies hiring design, fabrication and packaging talent. 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.
