The Opportunity

They are seeking a Lead Data Scientist to join a high-impact Directorate of Data Science and AI at the heart of Great Britain’s national infrastructure. This is not a “typical” tech role; you will lead the development of digital products and decision-support tools that directly improve the safety, efficiency, and sustainability of a major national network.

  • Modernisation: Take an active interest in emerging tools (including Agentic frameworks and Generative AI) to strengthen the team’s capability.
  • Mentorship: Provide technical guidance, code reviews, and coaching to junior scientists to build a culture of excellence.
  • Operational Excellence: Uphold best practices in coding, documentation, and Reproducible Analytical Pipelines (RAP).
  • Collaboration: Work closely with subject matter experts and architects to ensure outputs are robust and ready for real-world operational use.

Your Profile

They are looking for a candidate who values rigour as much as innovation. You likely have a background in the Public Sector, Government (Grade 7 equivalent), or a highly regulated industry.

Essential Experience:

  • End-to-End ML: Proven experience delivering applied data science projects from feature engineering to deployment.
  • Python Mastery: Expert-level Python skills with a focus on code structure, testing, and version control.
  • Governance: A deep commitment to reproducibility, model assurance, and secure data workflows.

Desirable:

  • Experience deploying models within Azure cloud environments.
  • Familiarity with Safety-Critical environments (e.g., Transport, Energy, Healthcare).
  • Experience with agentic frameworks or modern AI orchestration.

Why Apply?

This organisation is renowned for its commitment to staff wellbeing and professional development.

  • Work-Life Balance: 30 days annual leave (plus bank holidays), flexible core hours, and hybrid working.
  • Health & Future: Private medical and dental cover, performance-related bonus, and a highly competitive pension scheme.
  • Impact: Your work will have a tangible effect on the safety and sustainability of national infrastructure used by millions.
