Job Description:

Overview

I’m hiring a Data Scientist for a large, well‑known UK business investing heavily in its data, analytics, and AI capability. This is a brilliant opportunity for someone from an advanced analytics background who has started moving into modelling and wants to take the next step into a true data science role – working on real use cases like customer segmentation, forecasting, and personalisation.

About the Company

A major UK business with a strong national presence, currently building out its data and analytics function under a new leadership team. There’s a big focus on using data to drive customer strategy and commercial performance, especially with the launch of a new loyalty programme later this year – creating real demand for modelling and insight.

Where you fit

You’ll sit within a growing Data Science & Analytics team, reporting into the Data Science Lead and working closely with the Head of Data & Analytics.

What you’ll be doing

  • Build and apply models across key retail use cases such as:
    • Customer segmentation
    • Customer lifetime value modelling
    • Demand forecasting
  • Work with stakeholders to define business problems and translate them into analytical solutions
  • Develop models using Python + SQL
  • Support moving models towards production (with guidance from the team)
  • Contribute to the development of personalisation and loyalty analytics strategies
  • Work across the full lifecycle: problem → modelling → insight → business impact

What you bring

  • 2-4 years’ experience in analytics/data roles
  • Strong SQL
  • Experience using Python (preferred) or R for modelling
  • Experience building models (e.g. regression, segmentation, forecasting)
  • Ability to break down business problems and apply analytical thinking
  • Strong communication skills – able to work with non‑technical stakeholders

Nice to have

  • Exposure to loyalty programmes
  • Any experience taking models toward deployment
  • Strong academic background in a quantitative subject

Why this role

  • Step up into a true data science role from analytics
  • Work on real, high‑impact use cases tied to a major loyalty programme launch
  • Join at an early stage of the data science journey
  • Strong mentorship from experienced leaders
  • Opportunity to grow with the team as it scales

Working style

  • Based in Knowsley
  • 3 days per week onsite
  • Collaborative, fast‑growing team environment

Interview process

  • Initial call with Hiring Manager (CV walkthrough)
  • Onsite technical interview with leadership team

If you’re an analyst who’s started building models and wants to properly step into data science, this is a great opportunity to do it in a supportive but impactful environment.
