Senior Data Scientist

You’ll design, build and deliver agentic AI and LLM solutions for clients, from first idea through to production. You’ll lead a small team of data scientists, work closely with consultants and client stakeholders, and help shape how the team delivers AI work as it grows.

What you’ll do

• Build and deploy agentic and LLM-based systems that clients rely on
• Write production-quality Python and SQL
• Deploy and run solutions on cloud platforms (GCP, AWS or Azure)
• Lead, mentor and develop data scientists on client projects
• Explain complex technical work clearly to non-technical clients
• Help shape new AI offerings as the team grows

• Hands-on experience building and shipping agentic or LLM systems into production, not just prototypes
• Strong Python and SQL
• Experience with at least one major cloud platform
• Experience leading people or a delivery team
• Clear, confident communication with stakeholders

Nice to have

• Consulting or client-facing delivery experience
• Experience evaluating and monitoring LLM systems (testing, guardrails, cost control)
• MLOps tools such as MLflow, Airflow or CI/CD pipelines

Our client is a global data and AI consultancy, helping some of the world’s best-known organisations turn data and AI into real business results. Their London team is growing fast, and agentic AI is a big part of their work with clients.
