About the role
We file this job under Data Scientist, by the work the posting describes.
Data scientists use statistics and models to answer harder questions, such as whether a change worked, what demand will look like next quarter, or which customers are likely to leave.
Postings usually ask for Python or R, SQL, statistics, experiment design and common machine learning methods.
Unlike an ML engineer, a data scientist's main output is often an analysis or a first model, not software running inside a product.
VOIS (Vodafone Intelligent Solutions) is a strategic arm of Vodafone Group Plc, creating value for customers by delivering intelligent solutions through Talent, Technology & Transformation.
As the largest shared services organisation in the global telco industry with 30,000 FTE, our portfolio of next-generation solutions and services are designed in partnership with customers across Vodafone Group, local markets, and partner markets to simplify and drive growth. With our strategic partner Accenture, we work alongside our Vodafone customers, other Telco and tech companies to drive transformation, meet the challenges of our industry and ensure we stay relevant and resilient. This partnership is a unique, industry-first model which brings together the best of in-house and 3rd party capability.
We work with customers across 28 countries from 10 VOIS locations: Albania, Egypt, Hungary, India, Romania, Spain, Turkey, UK, Germany, Ireland, and with a network of teams in Czech Republic, Italy, Greece, and Portugal.

About this role
We are seeking a Lead Data Scientist to provide senior scientific leadership for Data Science and applied-model development within Digital Engineering, Digital & IT.
Based flexibly in Newbury or Paddington, UK, you will translate customer, commercial and operational challenges into testable analytical approaches, lead modelling and experimentation, and ensure models are statistically sound, reproducible, explainable and fair.
Reporting to the Data Products & Insights Lead, you will define what should be modelled and how scientific validity should be established. You will work closely with Product, Data Engineering and ML & AI Engineering, with the Senior ML & AI Engineer responsible for reliable production engineering.
This role has no direct or dotted-line reports and is focused on scientific leadership, technical judgement and measurable real-world impact.
What you’ll do
Frame customer, commercial and operational challenges as testable Data Science questions, defining outcomes, baselines, assumptions, decision thresholds and measures of value.
Lead the development and validation of predictive, forecasting, propensity, anomaly and fraud, optimisation and causal models for prioritised use cases.
Define appropriate experimental design, sampling approaches, feature strategies, evaluation methods and statistical tests based on the decision being supported and the available data.
Lead modelling, experimentation and scientific validation, ensuring analytical approaches are proportionate to the problem and evidence available.
Set and assure scientific standards for reproducibility, peer review, explainability, fairness, bias, uncertainty and model limitations.
Evaluate model validity and recommend whether models should proceed, be redesigned or stop where sufficient validity or value cannot be established.
Partner with Product, Data Engineering and ML & AI Engineering to ensure validated models are actionable and suitable for productionisation.
Measure post-launch performance and real-world customer or business impact to establish whether deployed Data Science solutions are achieving their intended outcomes.
Provide scientific input into data, tooling and experimentation choices.
Support effective transition of scientifically validated models into reliable production environments while maintaining clear accountability between Data Science and ML/AI Engineering.
