AI / Machine Learning Engineer

Job Overview

AI / ML Engineers build, evaluate, and deploy machine learning systems at scale. The day to day work combines data preprocessing, model training (PyTorch, TensorFlow), evaluation against business or research metrics, and production deployment (FastAPI, Triton, Ray) with monitoring. The role increasingly overlaps with MLOps (model deployment, monitoring, retraining infrastructure) and applied ML research, taking new techniques from papers to production. Generative AI (LLMs, diffusion models) is the most active area of UK ML hiring in .

Responsibilities

• Train, evaluate, and deploy machine learning models in production.
• Work across LLMs, computer vision, recommender systems, and forecasting.
• Specialise into ML research, MLOps, applied ML, or generative AI.
• Work for UK AI labs (DeepMind, Anthropic), fintechs, scale ups, and major corporates.

Skills & Qualifications

• Reading and implementing academic papers.
• Communication of complex technical concepts to non technical stakeholders.
• Rigorous experimental design and analysis.
• Comfortable with uncertainty and dead ends.
• Continuous learning across rapidly evolving methods.

UK Salary Ranges

UK AI / ML pay sits at the very top of the tech salary scale. London AI labs (DeepMind, OpenAI, Anthropic London, Cohere London) pay £100,000-£180,000 base + equity / RSU for new MSc / PhD graduates, totaling £150,000-£280,000. Top UK fintechs and scale ups (Monzo, Wise, OakNorth, Stripe UK) pay close to global rates for ML engineers. Mainstream UK corporates pay £55,000-£95,000.

Typical Entry Routes

PhD route (4-6 years): for research focused careers at AI labs (DeepMind, OpenAI, Anthropic). UK PhDs in ML / AI from Cambridge, Oxford, UCL, Edinburgh and Imperial are heavily recruited globally.

Software engineering conversion (1-2 years): experienced software engineers regularly move into ML engineering via online courses, portfolio projects, and on the job specialisation.

Global Talent visa: for published AI researchers, the UK Global Talent visa offers an alternative to the Skilled Worker scheme, endorsed by institutions such as The Alan Turing Institute or the Royal Society.

Typical Career Path

• Junior ML Engineer / Applied Scientist - Build core ML engineering skills under senior guidance; run experiments, evaluate models, deploy small production features.
• ML Engineer / Applied Scientist - Own end to end ML projects from problem framing through to production deployment, specialising in a domain (NLP, vision, recommender systems, time series).
• Senior ML Engineer / Senior Scientist - Lead the technical design of major ML systems; mentor a small group of engineers / scientists and own cross team ML strategy.
• Staff / Principal ML Engineer - Set ML direction across multiple teams; drive applied research, model strategy and major system decisions; often the highest paying non management role at UK AI labs.
