Hiring trends we’re seeing for 2025
Generative AI permeates everything – Over 60 % of adverts mention LLM fine‑tuning, RAG pipelines or diffusion models.
MLOps is now non‑negotiable – Roles citing GitOps, feature stores & model registries outnumber pure‑research posts three‑to‑one.
GPU engineering skills command premiums – PyTorch‑CUDA, Triton & TensorRT add ~25 % to median salaries.
Responsible AI moves front‑and‑centre – Explainability, bias testing & model governance requested in one‑third of ads.
Hybrid working dominates – Three office days is standard, though many scale‑ups (Synthesia, Lifebit) remain remote‑first.
