• Core Duties
• Design, develop, and test solutions to collect, integrate, and prepare data for advanced analytics and machine learning applications.
• Analyse complex datasets to uncover trends, patterns, and actionable insights that drive business or operational outcomes.
• Build, prototype, and evaluate statistical and machine learning models to solve real-world problems, testing feasibility and estimating impact before full deployment.
• Engineer and implement ML-based solutions, owning the full lifecycle – from model development and deployment to monitoring and iteration.
• Deploy models into production environments, handling the integration and operationalisation of ML within wider systems and applications.
• Continuously evaluate and monitor model performance, identifying degradation, performance gaps, or opportunities for optimisation.
• Collaborate closely with data analysts, engineers, and other stakeholders to define new tools, enhance workflows, and support innovation across teams.
• Communicate findings, recommendations, and model outcomes to both technical and non-technical audiences through visualisation and data storytelling.
• Research emerging AI/ML techniques to stay ahead of the curve and identify new opportunities to enhance current systems.
• Ensure all data science and ML practices adhere to relevant ethical standards, policies, and governance frameworks.
• Provide technical guidance and mentorship on ML implementation across cross-functional teams.
• Data Science and Analytics
• Use and design of algorithms is expected from the data scientist, to extract meaningful, actionable insight from a variety of datasets.

• You are comfortable working across the full machine learning lifecycle – from exploratory data analysis and model prototyping to production deployment, integration, and ongoing monitoring.
• You are proficient in Python and its data/ML ecosystem (e. g. pandas, scikit-learn, Py Torch, Tensor Flow), and you can apply statistical and machine learning techniques confidently in real-world settings.
• You have deployed models into live systems and understand how to make ML operational – whether that means working with APIs, integrating into existing applications, or using containerisation tools like Docker.
• You actively monitor the performance of deployed models, and are experienced in identifying drift, re‑training triggers, or opportunities for optimisation.
• You stay current with the latest advancements in machine learning and AI and enjoy applying new methods or tools to improve systems and outcomes.
• You are aware of the ethical and governance considerations that come with deploying machine learning at scale – such as bias, fairness, explainability, and compliance – and you incorporate these into your work.
• You are a strong communicator who can translate complex technical work into clear insights and recommendations, adapting your message to suit both technical and non-technical stakeholders.
• You enjoy working in cross‑functional teams, contributing your expertise while collaborating with analysts, engineers, product teams, and decision-makers.
