Hiring Trends We’ve Spotted for 2025
Generative AI everywhere – even “traditional” employers (banks, retailers, the NHS) list “prompt‑engineering” or “LLM fine‑tuning” in job ads.
MLOps is the bottleneck – roles requesting Kubernetes, Kubeflow, MLflow & Infrastructure‑as‑Code now out‑number pure research roles 3:1.
Salaries keep climbing – hedge funds are dangling £160–£250 k base for senior ML engineers plus seven‑figure upside on performance.
Hybrid beats remote – three days in‑office is now the UK norm, though start‑ups still offer remote‑first packages to secure scarce talent.
