Most companies try to meet expectations, dunnhumby exists to defy them. Using big data, deep expertise and AI-driven platforms to decode the 21st century human experience – then redefine it in meaningful and surprising ways that put customers first. Across digital, mobile and retail. For brands like Tesco, Coca-Cola, Procter & Gamble and PepsiCo.

We’re looking for a talented Research Data Scientist who expects more from their career. It’s a chance to extend and improve dunnhumby’s Category Management scientific portfolio. It’s an opportunity to work with a market-leading business to explore new opportunities for us and influence global retailers.

Joining our Data Science team, you’ll work with world class and passionate people to apply machine learning and other data science techniques to business problems, including sales and performance prediction, clustering and community structure, and optimisation. You’ll support our high-performing Category Management experts to translate retail challenges into data science problems, identify creative model implementations to improve performance on complex problems, perform data analysis and model validation, and work with developers to productionise your science. You’ll also have the opportunity to document and present analysis to internal teams and clients.

Degree or equivalent with a substantial component of mathematics or statistics
Good understanding of machine learning techniques, including regularised regression, clustering, tree-based ensembles, natural language programming and neural networks, with a desire to apply these efficiently to industry problems
An awareness of core statistical and mathematical methodologies concepts. Examples could include statistical inference, probability distributions, confidence intervals, hypothesis tests and optimization.
Ability to prototype solutions using open source software (eg Python, Spark) to facilitate testing of algorithms on large data sets.
Knowledge of, and an ability to apply, design methodologies in order to rigorously evaluate proposed approaches.
Experience with handling large data volumes with modern data processing tools, e.g. by using Hadoop / Spark / SQL Analytical Techniques.
An interest in presenting your work to both technical and non-technical audiences and to contribute to the wider data science community.
It is desirable to have a postgraduate degree or recent relevant experience of conducting research projects, especially in the domains of statistics, market science or machine learning.
Familiarity with coding principles, such as version control and unit tests, and tools such as git would also be beneficial.
