Your work will ensure our data-driven solutions are robust, scalable, and impactful.
Key Responsibilities
Key Contributions:
• Deliver data solutions and services that optimize customer connections across channels.
• Transform our complex IT data estate by unifying disparate data sources into a single, managed version of the truth.
• Ensure data integrity through central data mastering and modelling, enabling colleagues to interact with data to meet their needs.
• Simplify data integrations between systems via a central platform, enhancing user experience and minimizing risk.
• Promote a culture of data-driven experimentation, showcasing the value of our data through insights and analytics, and demonstrating emerging tech tools.
Key Responsibilities:
• Develop and own data science solutions, applying statistical/machine-learning models for segmentation, classification, optimisation, and time series analysis.
• Present findings to the wider team and organisation.
• Identify insights and suggest recommendations to influence business direction.
• Develop and optimise churn prediction models to understand customer retention patterns and implement mitigation strategies.
• Build forecasting models to predict business KPIs, customer lifetime value, and revenue trends using machine learning and statistical techniques.
• Integrate Large Language Models (LLMs) into RAG-based systems to improve knowledge retrieval and decision support for enterprise applications.
• Collaborate with data engineers to design scalable data pipelines for machine learning model deployment and inference at scale.
• Work with cross-functional teams to translate business problems into data science solutions.
• Develop ETL processes and data transformation workflows for structured and unstructured data.
• Utilise big data technologies like Spark and Snowflake to process, store, and analyse large datasets efficiently.
• Optimise and fine-tune LLMs to improve their performance within RAG systems and ensure alignment with business goals.
• Perform A/B testing and statistical analyses to validate model effectiveness and recommend improvements.
• Communicate findings and insights to stakeholders through compelling data visualizations and presentations.
Skills, Know-How, and Experience:
• Strong proficiency in Python (Pandas, NumPy, Scikit-learn, PyTorch/TensorFlow) and SQL.
• Experience with big data frameworks such as Apache Spark, Databricks, or Dask.
• Hands-on experience with cloud platforms like AWS (S3, Lambda, SageMaker, Redshift), Azure, or GCP.
• Knowledge of Snowflake, including Snowpark for scalable data processing and ML integration.
• Familiarity with MLOps principles, CI/CD pipelines, and model deployment in production environments.
• Knowledge of NLP techniques and experience with transformer-based LLMs (e.g., OpenAI, Llama, Claude).
• Strong understanding of machine learning algorithms for classification, regression, clustering, and time series forecasting.
• Experience with data visualisation tools such as Tableau, Power BI, or Python-based libraries (Matplotlib, Seaborn, Plotly).
• Excellent problem-solving skills, analytical thinking, and ability to communicate complex technical concepts to non-technical stakeholders.
• Experience in customer analytics, digital marketing, or e-commerce industries.
• Familiarity with vector databases and embedding-based retrieval techniques for RAG implementations.
• Familiarity with modern agentic AI techniques eg Model Context Protocol (MCP)
Technical/Professional Qualifications:
• Degree in a quantitative discipline (applied mathematics, statistics, computer science, operations research, or related field).
• Demonstrable experience in exploratory data analysis and feature engineering.
• Experience with Python, Scikit-learn, PyTorch. Ideally, experience with PySpark, Snowflake, AWS, and GitHub (MLOps practices).
