About the role
The Machine Learning Engineer role sits within Client Delivery, embedded in the Data & Analytics Consulting (DACs) team — a technical, client-facing group of Data Scientists and ML Engineers responsible for building and operationalising advanced machine learning and AI.
Responsibilities
•Design, train and optimise predictive models (gradient boosted trees, temporal and embedding-based models), with reproducible training, evaluation and monitoring pipelines
•Productionise models to run reliably at scale in client environments
•Build and integrate LLM components (embedding pipelines, RAG, agentic systems) and NLP models for extraction, classification and risk prediction
•Own versioned, validated data flows for modelling and inference, including schema design and SQL optimisation for large training and scoring workloads
•Extract data from client source systems and build cohort logic that is accurate and interpretable
•Lead the modelling and data engineering components of client projects alongside DACs and Business Consultants, resolving complex modelling and pipeline issues
•Configure OneView components linked to modelling outputs (risk logic, summaries, scoring pathways) and feed engineering improvements back into the platform
•Act as SME for machine learning and AI within DACs
•Mentor DACs on Python, modelling practice and debugging
•Produce documentation, templates and reusable components that raise delivery standards
Requirements
•3–5+ years' experience in machine learning engineering, taking models from development into production
•Strong Python skills and experience with modern ML frameworks, including training and evaluating tree-based, temporal, NLP or LLM-based models
•Experience building reproducible training and evaluation pipelines, and containerising and deploying models (for example, Docker, FastAPI)
•Strong SQL, a solid grounding in relational databases, schemas and data transformations (ideally DBT), and experience preparing data for model training and scoring
•Hands-on AI experience: embeddings, vector databases or RAG workflows, and NLP or sequence models applied to real-world datasets
•Experience delivering technical work to clients or stakeholders, including defining data requirements and troubleshooting in real time
•Clear communication: you explain technical concepts simply and work closely with data scientists, engineers and consultants
Nice to have
•Experience with Azure ML, AKS or similar cloud environments
•Experience with public sector datasets or analytical workflows
Conditions
•This is a 12 months contract with potential to become a perm role afterwards
