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.

How to Maximise Your Applications

1. Tailor your CV to the stack each company lists – e.g. PyTorch → DeepMind, JAX → Graphcore, GCP → Revolut, ROS2 → Ocado.
