You’ll also collaborate in the creation of Data Science & AI Best Practice and provide expertise to other Ofgem departments and external stakeholders. It’s a role that requires an understanding of strategic business initiatives and analysis, data assets, and Data Science product development as well as being able to use data visualisation and storytelling techniques to share conclusions and advise on impacts. 

It’s essential that you can bring mathematical, statistical and analytical/research skills and your knowledge in the development of data science, machine learning, analytics or statistical data products should include a core data science language.
