• Work with client stakeholders, product owners and technical teams to understand operational challenges and translate them into practical ML solution designs.
• Design, build, test and deploy machine learning models, analytical pipelines and data science components that are robust, scalable and maintainable.
• Support the operationalisation of ML solutions through MLOps practices, including model monitoring, versioning, automated testing, CI/CD and performance optimisation.
• Apply responsible AI, model explainability, security, privacy and governance considerations throughout the development lifecycle, particularly within secure and regulated environments.
• Collaborate with solution architects, data engineers, data scientists, business analysts and delivery leads to integrate ML solutions into wider technology and business landscapes.
• Manage stakeholders and contribute to delivery leadership by communicating progress, risks, dependencies and technical recommendations clearly and confidently.

• Degree or equivalent experience in Computer Science, Data Science, Mathematics, Statistics, Artificial Intelligence, Machine Learning or a related discipline.
• Hands-on experience designing, developing and deploying machine learning or data science solutions in a consulting, commercial, public sector or technology delivery environment.
• Experience owning technical deliverables or workstreams, managing priorities and coordinating across multidisciplinary teams.
• Demonstrated ability to work with business and technical stakeholders to understand requirements, shape solution options and translate analytical outputs into practical recommendations.
• Experience delivering within secure, regulated or complex public sector environments is advantageous; candidates must be eligible and willing to obtain or hold the required security clearance for relevant client engagements.

• Strong proficiency in Python or another modern programming language used for data science and machine learning development.
• Practical experience with machine learning frameworks and libraries such as scikit-learn, XGBoost, PyTorch, TensorFlow or equivalent.
• Experience across the end-to-end ML lifecycle, including data preparation, feature engineering, model development, validation, deployment, monitoring and optimisation.
• Understanding of MLOps and production ML practices, including CI/CD, model versioning, automated testing, retraining, monitoring and reproducible delivery.
• Experience using cloud platforms and data science environments such as Azure, AWS, GCP, Databricks or equivalent to build and deploy scalable ML solutions.

We are subject to a number of audit regulations, one of which requires that certain colleagues abide by specific personal independence constraints (e.g., in relation to any financial interests and employment relationships). This can mean that you and your “Immediate Family Members” are not permitted to hold certain financial interests (shares, funds, bonds etc.) with audit clients of the firm, and also prohibitions on certain employment relationships (e.g., you are not permitted to hold a secondary employment role with SEC audit clients of the firm whilst being employed by the firm).
