Overview

At Aberdeen, our ambition is to be the UK’s leading Wealth & Investments group. We focus on strengthening talent and culture to attract and retain the industry’s best talent and to provide excellent client service supported by leading technology and talent.

Aberdeen comprises three businesses—Interactive Investor (ii), Investments, and Adviser—each focused on meeting and adapting to our clients’ evolving needs. Interactive Investor is the UK’s second largest direct-to-consumer investment platform; our Adviser business provides financial planning solutions and technology for UK financial advisers; and our Investments business is a specialist asset manager serving themes in public markets or alternative asset classes.

About The Department

At Aberdeen Adviser, the Product Insights team helps the business understand how products perform, what customers experience, and where new opportunities lie. We bring together data engineering, analytics, and data science to produce insights that drive real decisions. We work in cross-functional squads alongside product, engineering, and business colleagues. Curiosity and experimentation are part of our culture, and we’re embracing automation and new tooling to deliver faster and smarter. Most data science roles focus on building models; in Product Insights, we go further—helping shape the platform itself by equipping colleagues with tools to do their best work and helping customers get more value from every interaction.

About The Role

As a Data Scientist you’ll lead how we design, test, monitor, and govern models — from classical machine learning to agentic systems powered by large language models. You’ll report to the Head of Product Insights, with a broad remit to set direction and influence outcomes.

Key Responsibilities

• Leading the design, development, validation, and governance of machine learning and agent-based models, including large language models and AI agents, ensuring safety, explainability, and alignment with business goals.
• Developing and implementing inventive validation approaches and robust monitoring processes for models and agentic systems, including tracking behavior post-deployment for drift, bias, and fairness issues.
• Designing and running experiments such as A/B tests, quasi-experiments, and causal inference studies to test hypotheses, measure business impact, and optimise decision-making.
• Building scalable, reusable data pipelines for feature engineering and insight generation, automating workflows using Azure ML and Fabric, and applying best practices in MLOps for deployment and retraining.
• Collaborating cross-functionally with product, engineering, and business teams to translate complex data science outputs into actionable insights understandable to both technical and non-technical stakeholders.
• Mentoring junior colleagues and engaging senior leaders to shape data science strategy, promote a strong testing culture, support data governance, and drive the responsible adoption of emerging AI technologies in financial services.

About The Candidate

• Proficient in Python and/or R with strong engineering discipline and experience applying machine learning techniques including classical ML, NLP, and large language models (LLMs).
• Solid grounding in statistics, causal inference, and advanced AI methods such as reinforcement learning and agentic systems, with a proven track record in model validation, monitoring, and governance.
• Skilled in designing and running experiments including A/B testing, quasi-experiments, and causal inference for measuring impact and guiding data-driven decisions.
• Familiarity with Azure ML, Fabric, medallion architecture, and MLOps best practices for model deployment, scaling, monitoring, and retraining.
• Excellent communication skills capable of bridging technical and business teams, explaining complex data science outputs to diverse stakeholders.
• Curious, open-minded, and engaged with emerging trends in data science and AI; able to mentor colleagues and influence senior stakeholders on data strategy and governance.
