About the Role

Reporting into a Head of Data Science, you will lead a team of data scientists and analysts developing innovative AI capabilities that deliver great business outcomes for our Operational teams. Your team will be responsible for the end to end development of machine learning models, covering prediction, propensity, segmentation, Natural Language Processing, Generative AI (and more!). You’ll be responsible for engaging with different business teams to understand their data science needs and partnerships with your stakeholders.

You’ll also support the development of your team through mentoring and achievable career progression plans. This role is fundamental to Plan Zero, delivering the data science and insights that enables OVO to decarbonise customer homes, such as modelling customer behaviour or providing insights to manage energy consumption.

• Lead and encourage a multidisciplinary Data Science team, including specialists in machine learning, operational research, and data engineering, including the application of generative AI.
• Take ownership for the technical delivery of your team’s models and the analytics that support them. This includes ensuring models are well monitored and maintained after release.
• Collaborate with your peer group of data science managers to define the frameworks and practices that enable our Machine Learning specialists to have maximum impact.
• Work with external partners to tap into expertise and expand our capabilities. Assess ways to improve and supplement the data we collect, as well as the approaches we take.
• Champion the value of data science and advise on appropriate use of data in the business, actively exploring innovative approaches, particularly in generative AI.
