Hiring trends we’re seeing for 2025
Manufacturing scale‑out is back. Nearly half the ads we tracked were for GMP production, QC & supply‑chain roles – proof the UK is reshoring capacity post‑pandemic.
GenAI crosses the bench‑to‑business divide. From GSK’s biologics LLM team to Genomics England’s HPC bio‑informatics stack, generative‑AI is now mainstream in wet‑lab & data functions.
Salary inflation is real. Glassdoor shows London Senior Scientists averaging £50 k – £65 k base in June 2025 glassdoor.com, with hot skills (single‑cell, cell therapy, MS‑based proteomics) commanding 20 % premiums.
Hybrid beats remote. Three days on‑site is the new normal, but bio‑informatics‑heavy employers (Lifebit, BenevolentAI) still lead with remote‑first contracts.
Regulatory & Quality talent shortage. MHRA’s new “Innovation Pathway” plus EU CTR rollout mean RA/QA hiring has spiked 40 % quarter‑on‑quarter on our board.
