Are you passionate about shaping the next generation of AI-powered products?

Join a dynamic, fast-moving business that’s embedding AI into everything from customer interactions to internal tools.

We’re looking for an experienced Data & AI Scientist to help drive innovation across cutting-edge AI initiatives — from chatbots and voice assistants to advanced retrieval-augmented generation (RAG) systems and agentic workflows.

You’ll work closely with the AI Engineering and Data Science teams to:

• Develop and prototype AI-driven solutions across customer-facing and internal applications.
• Build and optimise LLM-based assistants
  , RAG pipelines
  , and agentic AI workflows
  .
• Collaborate on the architecture and deployment of scalable AI solutions (with support from engineering).
• Partner with stakeholders to translate business needs into practical, intelligent systems.
• Mentor junior team members and contribute to the evolution of our AI tooling stack.

This role is ideal for a hands‑on AI practitioner who enjoys experimentation, collaboration, and delivering real‑world value.

• 3+ years experience in a commercially driven customer environment
• Strong Python skills and solid grounding in AI/ML fundamentals.
• Experience with some of Databricks,
  Lang Chain
  , vector databases
  , or LLM orchestration tools
  .
• Knowledge of RAG pipelines
  , transformers
  , and modern AI architectures
  .
• Understanding of deployment or MLOps best practices (Azure experience a plus).
• Recent, hands‑on experience with applied LLM projects
  .
• Strong communication and stakeholder engagement skills.

A Master’s degree in Computer Science, ML, or AI is preferred but not required.

• Be part of an ambitious AI journey - already 70% built, with big plans for the next 5 years.
• Contribute to short-term LLM “quick wins” and longer-term agentic AI development
  .
• Work in a collaborative, supportive environment with senior data leaders.
• Help shape how AI transforms both customer experience and business efficiency.
• Salary:
  Up to £80,000 + 10% Bonus + 5% Matched Pension
• Hybrid working: 3 days per week in London office (Tues/Weds fixed)
