Maths for Semiconductor Jobs: The Only Topics You Actually Need (& How to Learn Them)

If you are aiming for semiconductor jobs in the UK it is easy to assume you need a PhD level maths toolkit. In practice most roles do not. Whether you are targeting device engineering, process engineering, yield engineering, product engineering, test, reliability, RF, analogue, digital design, EDA, packaging or applications engineering, the maths you actually use clusters into a few workhorse areas. This guide strips it back to the topics that genuinely help you get hired & perform well on the job: Exponents, logs & “physics curves” (Arrhenius style behaviour, subthreshold, leakage) Calculus in plain English (rates, gradients, differential equations intuition) Device electrostatics & transport basics (Poisson equation intuition, drift & diffusion) Complex numbers for AC & RF (impedance, phasors, frequency response) Signals maths (Fourier intuition, bandwidth, noise density) Probability & statistics for manufacturing (SPC, DOE, yield models, reliability basics) Basic optimisation habits (fitting models, tuning trade-offs, making decisions with data) You will also get a 6 week plan, portfolio projects & a resources section you can follow without getting pulled into unnecessary theory.

Neurodiversity in Semiconductor Careers: Turning Different Thinking into a Superpower

Semiconductors sit quietly at the heart of everything: phones, cars, medical devices, satellites, data centres & everyday appliances. Behind every chip are people designing circuits, running fabs, testing wafers, modelling devices & solving problems most users never see. Those people are not all “textbook” engineers – & that’s a good thing. If you’re neurodivergent (for example living with ADHD, autism or dyslexia), you may have been told your brain is “too distracted”, “too literal” or “too disorganised” for a high-precision, high-reliability industry. In reality, many of the traits that made school or traditional offices hard can be huge strengths in semiconductor work: intense focus on detail, pattern-spotting in test data, creative thinking around yield & process issues. This guide is written for semiconductor job seekers in the UK. We’ll cover: What neurodiversity means in a semiconductor context How ADHD, autism & dyslexia strengths map to chip & fab roles Workplace adjustments you can ask for under UK law How to talk about your neurodivergence in applications & interviews By the end, you should have a clearer sense of where you might thrive in the semiconductor industry – & how to turn “different thinking” into a genuine career advantage.

Semiconductor Hiring Trends 2026: What to Watch Out For (For Job Seekers & Recruiters)

As we move into 2026, the semiconductor jobs market is in that awkward phase of being both overheated and cautious. Global chip demand is booming again, driven by AI, data centres, automotive, defence, 5G and consumer electronics. Fab capacity is set to hit record highs as new plants come online worldwide. At the same time, we are seeing: Waves of investment and hiring in some regions and companies. Restructuring and layoffs in others, as firms rebalance portfolios and chase AI margins. A deepening global skills shortage, with forecasts of major shortfalls in engineers and technicians by 2030. For the UK, the sector is small but strategically vital. The National Semiconductor Strategy, public funding and participation in European chip programmes are all aimed at building domestic capability in design, compound semiconductors and advanced manufacturing. So what does all this mean for semiconductor jobs in 2026 – and for employers trying to recruit in a brutally competitive market?
