Hiring trends we’re seeing for 2025

• Power & compound surge. GaN, SiC and GaAs roles now account for nearly 40 % of ads as EV and 5G demand soar.

• Chiplets & 2.5 D packages rule roadmaps. Employers list HBM, interposers & advanced substrate know‑how in one‑third of postings.

• Software eats silicon… again. Python‑based yield analytics, ML‑for‑EDA and Design‑Space‑Exploration appear in half of design‑house adverts.

• Security clearance premiums rise. Defence, IR sensor and sovereign‑chip projects pay up to 30 % extra for SC/DV‑cleared engineers.

• Hybrid beats fully remote. Three cleanroom or lab days per week is standard, yet many EDA and FA roles remain remote‑first.

How to maximise your applications

1. Tailor your CV – quantify yield gains, power reductions or tape‑out wins; highlight clean‑room certifications & EDA tool fluency.

2. Use our search filters – try “GaN + Newport”, “chiplet + contract”, or “EDA + remote” on SemiconductorJobs.co.uk.

3. Set a job alert – we’ll email you as soon as the Hotlist is refreshed (next edition: October 2025).

4. Network smartly – attend events like CS International, Silicon UK Summit, DVClub Europe & SEMICON Europa; many employers above sponsor & interview on‑site.

5. Upskill continuously – master RF‑EM co‑sim, Design‑Technology‑Co‑Optimization (DTCO) & ISO 26262 for automotive ICs to stay in demand.
