  • Identifying new approaches and methodologies to develop how we do things.
  • Being the first port of call when it comes to leveraging our Group-wide dataset.
  • Ensuring every piece of code and output we deliver is documented, repeatable, scalable and sharable via appropriate, collaborative tools (e.g. Git, Confluence).
