Permanent | Consulting (Customer & Data Analytics Practice)

Overview

A global consulting firm is building a new London-based Customer Data Science capability within its broader customer, digital, and marketing practice.

The team focuses on combining customer experience, data science, and applied AI to help large consumer-facing organisations improve commercial performance, customer engagement, and marketing effectiveness. This is a newly scaling capability with strong investment and the opportunity to shape how advanced customer analytics and GenAI are applied in real-world client environments.

The Role

You will deliver hands-on data science and customer analytics work across a range of consumer-focused client projects. This is a delivery-heavy role combining technical data science with commercial problem solving and client-facing consulting, with a fast track to Management.

Typical work includes:

• Customer behaviour analysis and segmentation
• Marketing and CRM performance analytics
• Loyalty and retention modelling
• Web, product, and digital analytics
• Predictive modelling and forecasting
• Applied GenAI / LLM use cases in customer and marketing contexts
• Personalisation and optimisation initiatives

Requirements

• Strong hands-on Python and machine learning experience
• Ability to build and deploy predictive models (classification, regression, clustering, forecasting)
• Experience working with customer, CRM, marketing, or digital behavioural data
• Exposure to GenAI / LLM-based applications (build, evaluate, or implement use cases)
• SQL proficiency
• Strong stakeholder communication skills
• Ability to translate data insights into commercial recommendations
• Experience in a consulting, agency, or in-house analytics environment

Consulting experience is beneficial but not essential. Strong candidates from consumer-facing or agency backgrounds are welcome.
