Job Responsibilities

We are seeking a Senior Data Scientist with deep expertise in statistical modelling, machine learning, and business analytics to drive revenue growth through advanced analytical solutions. In this role, you will design and deploy predictive models including cross-sell, upsell, deep-sell, and look-alike models that directly impact product strategy and customer engagement. You will leverage AWS SageMaker for end-to-end model automation and harness Large Language Models (LLMs) including Claude/Anthropic to enhance productivity, personalisation, and insight generation at scale.

You will work closely with product owners, marketing, and business stakeholders to translate complex data patterns into actionable insights at both product and customer levels, ensuring analytical solutions drive measurable business outcomes.

Key Responsibilities

• Design, build, and deploy advanced ML models for cross-sell, upsell, deep-sell, and look-alike use cases to maximise customer lifetime value and revenue per customer.
• Develop customer segmentation, propensity scoring, next-best-action, and recommendation engines that inform personalised engagement strategies.
• Automate end-to-end model lifecycle (training, validation, deployment, monitoring) using AWS SageMaker Pipelines and MLOps best practices.
• Leverage LLMs (Claude/Anthropic) and AWS Bedrock for insight generation, automated commentary, personalised content creation, and agentic workflows that augment human decision-making.
• Translate model outputs into clear, actionable business recommendations for product managers, marketing leads, and senior leadership.
• Conduct rigorous A/B testing and champion-challenger frameworks to measure model impact on business KPIs.
• Collaborate with data engineering teams to ensure robust feature pipelines and data quality for model inputs.
• Mentor junior data scientists and establish best practices for model development, documentation, and reproducibility.

In order to be successful at this role, you must have the following:

• Proven track record building and deploying production-grade predictive models (propensity, recommendation, segmentation, LTV).
• Deep expertise in statistical methods: regression, classification, ensemble methods, Bayesian inference, time-series analysis.
• Strong proficiency in Python (scikit-learn, XGBoost, LightGBM, PyTorch/TensorFlow) and SQL.
• Hands-on experience with AWS SageMaker (Training Jobs, Endpoints, Pipelines, Feature Store) for model automation and deployment.
• Experience with LLM/GenAI tools (Claude, GPT) for prompt engineering, RAG architectures, and AI-assisted analytics workflows.
• Exceptional business acumen - ability to connect data patterns to revenue, cost, and customer experience outcomes.
• Strong communication skills to present complex findings to non-technical stakeholders.

Preferred Qualifications

• Experience with AWS Bedrock for building GenAI-powered applications and agents.
• Familiarity with causal inference methods and uplift modelling for campaign optimisation.
• Experience in retail banking products (cards, lo
