Data Scientist – GenAI & AI Engineering

Internal Grade D/EB8

Data Scientist – GenAI & AI Engineering

The Generative AI Centre of Expertise (GenAI CoE) at Experian helps teams across Experian's UK business. It improves products using Generative AI, machine learning, and automation. The centre has a focus on responsible, measurable impact.

Who is a GenAI CoE Data Scientist?

This is a mid-level, hybrid role for a data scientist who enjoys hands-on work and wants to grow into AI engineering. You'll report into the Head of Machine Learning and work across two connected areas:

• Experimentation and evaluation (data science): framing problems, designing experiments, defining success metrics, analysing results, and understanding model/system behaviour in product contexts
• AI engineering: build GenAI systems (prototypes through to production-ready components), supported by experienced colleagues

A big part of the job is choosing the right approach — when GenAI is valuable, and when simpler analytics or ML is the better answer.

What you'll do

• You will work with product, engineering, and business teams to turn fuzzy ideas into clear problem statements, assumptions, and success metrics
• You will design and run experiments to evaluate GenAI systems, including baseline comparisons, error analysis, and understanding failure modes
• Help refine GenAI solutions, using modern development practices and AI-assisted coding tools to iterate quickly
• Communicate results, including trade-offs, limitations, and recommendations for what to do next
• Share insights with the team and spend ~10% of your time on learning and knowledge sharing

• You have experience working as a data scientist (or in a similar role), applied machine learning, and Python programming.
• You are comfortable working with incomplete information, and enjoy figuring things out through exploration and experimentation.
• You are keen to develop broader skills across AI engineering and product-focused delivery.
• You think beyond your scope: you join up product, data, and engineering context to spot issues early and improve decisions.

It would be great if you also have

• Exposure to software engineering practices such as version control, testing, or object-oriented programming.
• You will understand how companies deploy or run AI systems in practice through cloud services or containerised environments.
• Experience explaining technical concepts or analysis to non-technical partners.
