About the Role
When you see the world as we do, you see the chance to help the world take better care of its resources and help it become a better place for everyone. Veolia is looking for a committed leader to push for genuine change and bring our ambition of Ecological Transformation to life. As Head of Flexibility, you will own, grow, and transform our flexibility portfolio, powering Britain's transition to a cleaner, smarter energy future.

This is a unique opportunity to define the strategy for a rapidly growing, high-impact team at the cutting edge of energy flexibility, battery storage, grid balancing, and demand-side response. You will be the commercial owner and operational leader of a portfolio already generating £6M+ in revenue, with a gross margin target exceeding £5.5M, and have the mandate to grow it further.

Reporting to the Director of Energy Markets, you will set the vision, shape investment decisions, and ensure Veolia captures maximum value from a rapidly evolving energy landscape.

You will:
- Lead with strategy by defining and implementing Veolia's UK flexibility services strategy, evaluating new markets, building board-ready business cases, and advising on investment decisions.
- Own the commercial agenda by growing Veolia's Capacity Market activities and developing an external-facing Flexibility Services offering targeting £1M+ in new revenue.
- Build a winning team by coaching, developing, and hiring talented people, creating a high-performance culture built on ownership, accountability, and shared purpose.
- Champion decarbonisation by integrating flexibility into Veolia's ecological transformation agenda, enabling local energy loops, circular economy models, and a low-carbon future.
- Be the face of flexibility by representing Veolia at industry forums, engaging with customers across Municipal, Commercial, Treatment, and IWE sectors, and positioning Veolia as the UK's trusted flexibility partner.

At Veolia, we are on a mission to reshape the world through ecological transformation, smarter resource management, and a commitment to a sustainable future. You will collaborate across Veolia UK's business units and connect with Veolia Group internationally to ensure the UK leads the way in global flexibility best practice.

- Strong modelling skills in Python, Excel, and SQL
- Proven track record of setting direction and delivering results through leadership
- Experience influencing senior leaders and managing relationships with NESO, DSOs, and regulatory bodies
