Support supplier evaluation and make/buy decisions Die Attach Process Engineering

Develop and optimise processes including silver epoxy, silver sinter and eutectic attach (AuSn)

Define process parameters (temperature, pressure, time and atmosphere)

Deliver process validation, qualification and reliability testing

Characterise bond performance including voiding, bond line thickness and thermal resistance

Support material selection and supplier development Wire Bonding Development

Establish and optimise gold wire and ribbon bonding processes (ball and wedge)

Define process parameters across varying substrates and metallisation types

Perform mechanical testing (pull/shear) and reliability assessments

Resolve bonding challenges including intermetallic formation and pad integrity

Support fine-pitch and high-frequency assembly requirements Manufacturing & Continuous Improvement

Define, document and control manufacturing processes and workflows

Develop SOPs, control plans and process documentation

Monitor process capability (SPC, Cp/Cpk) and drive yield improvements

Lead root cause investigations using structured methodologies (8D, DMAIC, FMEA)

Deliver continuous improvement initiatives targeting cost, quality and cycle time New Product Introduction (NPI)

Support DFM/DFA activities during product development

Develop pilot builds and process validation strategies

Work cross-functionally to ensure smooth transition into production

Define tooling, fixturing and automation requirements Requirements Essential

Degree in Engineering, Materials Science, Physics or related discipline

Experience in semiconductor or RF module manufacturing environments

Hands-on experience with at least one of the following:

Silver epoxy die attach

Silver sintering

Eutectic die attach

Gold wire bonding

Strong understanding of materials behaviour and thermal management

Experience in process validation and statistical analysis

Proven problem-solving capability within a manufacturing setting Desirable

Background in high-precision electronics, automotive or power electronics manufacturing

Experience in high-tech or semiconductor production environments

Knowledge of RF packaging and JEDEC standards

Experience with equipment specification and commissioning

Familiarity with thermomechanical modelling and reliability testing

Understanding of ISO 9001 or IATF 16949 quality systems Key Attributes

Analytical, structured and detail-oriented approach

Strong cross-functional collaboration skills

Ability to translate technical requirements into practical manufacturing solutions

Hands-on and proactive within a production environment

Comfortable working across both development and operations

Capable of managing priorities in a fast-paced, scaling organisation

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.
