Duties and Accountabilities

Delivery of data science products

• Deliver well-scoped data science projects, from data preparation and exploratory analysis through model development and validation. Working with team to deliver to production.
• Take on increasing ownership of the full lifecycle over time, including deployment and in-life monitoring of models you have built.
• Apply data science techniques to automate manual processes.
• Explore generative AI use cases, helping assess their value and fitness for the roadmap.
• Assess the quality and usefulness of internal and external data sources, working with data scientists and actuaries.
• Produce ad hoc analytics and insights for the business, coordinated through the Data Science and Data Analytics Manager.

Engineering standards

• Write clean, tested, version-controlled Python that follows team standards, and take part in code review as both author and reviewer.
• Contribute to machine learning pipelines in our cloud environment (Azure), learning the team's MLOps and CI/CD patterns through hands-on work.
• Monitor the performance of deployed products, engaging with business to track and measure adoption.
• Document models clearly and explain them to a standard appropriate for a regulated environment.

Stakeholder engagement and requirements

• Spend time with underwriting teams to understand how each class operates and where data science can add value.
• Help capture and document requirements for data science products.
• Work with IT and Data Engineering on the data that projects depend on.
• Communicate findings, and their limitations, clearly to non-technical audiences.

​​
Skills, Knowledge and Experience

Essential

• Solid Python for data science, with readable, well-structured code and an understanding of functions, classes and modules.
• Machine learning across the standard toolkit (scikit-learn, pandas, NumPy, statsmodels or equivalents), with sound judgement about validation and the limits of what the data supports.
• Statistical foundations: hypothesis testing, regression, quantifying uncertainty and recognising when a conclusion is not supported.
• SQL, with the ability to query and join relational data efficiently.
• Data wrangling and preprocessing, including ambiguous, incomplete and inconsistent data.
• Working knowledge of Git and version control.
• Clear written and verbal communication, including explaining technical work to non-technical colleagues.

Desirable

• Evidence of linking analytical work to a business outcome, such as a cost saved, a decision changed or a process automated.
• Experience working directly with business stakeholders on requirements or adoption.
• Insurance experience, ideally in the Lloyd's market, pricing or underwriting, or exposure to actuarial methods.
• Object-oriented design, automated testing (eg. pytest) and code review as normal practice.
• Experience taking a model into production, or contributing to one that was.
• Exposure to MLOps and CI/CD concepts: pipeline orchestration, model versioning, automated deployment and monitoring.
• Dependency and environment management (eg. virtual environments, Docker).
• Distributed processing frameworks such as PySpark.
• Data visualisation and reporting, for example Power BI.

Behaviours and ways of working

• Curiosity about the business: asks why a problem matters and who will use the answer, not only how to model it.
• Growth mindset: seeks out feedback, acts on code review, and takes ownership of their own development.
• Pragmatism: recognises when a simpler solution is good enough and avoids over-engineering.
• Clear communication: explains results, limitations and uncertainty honestly to technical and non-technical audiences.
• Collaboration: works well across Underwriting, Actuarial, IT and Data Engineering, and shares what they learn.
• Reliability: manages their own workload, flags risks early and delivers on commitments.
