Applied machine learning engineer job description.
Thinking of bringing in an applied machine learning engineer or focusing your career on production-ready ML systems? This job description outlines responsibilities in applied data science, system integration, optimisation, and skills that command strong compensation in the UK market.
What does an applied machine learning engineer do?
An applied machine learning engineer focuses on solving specific business problems using machine learning models. Their work is grounded in real-world impact, often optimising recommendations, forecasts, or user behaviour predictions.
Key tasks include collaborating with domain experts, transforming business challenges into ML solutions, and deploying models that deliver measurable value. They often use platforms like SageMaker, Vertex AI, or Databricks alongside open-source tools.
In lean teams, they may work across feature engineering and model training. In enterprise settings, they embed within product squads, rapidly iterating and aligning outputs with KPIs such as retention, conversion, or fraud detection.

FAQS
Applied machine learning engineer FAQs.
Applied ML engineers focus on solving real-world problems with ML — not just building models, but embedding them into user-facing features or operational systems. They balance performance, maintainability, and product fit.
Search ranking, churn prediction, recommendation engines, logistics optimisation, or user segmentation. These engineers collaborate closely with product teams and must make practical trade-offs under deadline.
A focus on real outcomes — not just model scores. Look for those who’ve handled rollout planning, A/B tests, and user feedback loops. Experience building experimentation frameworks is especially valuable.
Applied ML lead, ML product manager, or roles that bridge AI and product strategy. It’s ideal for engineers who enjoy business impact and cross-functional collaboration.
