About the Role

As a Site Performance Manager, you will ensure that Thames Water employees and contractors work in a safe and secure environment, going home safely and well at the end of each day. You will be responsible for achieving planned availability and reliability of water production sites in terms of quality and quantity, while managing costs effectively.

You will ensure individuals understand their performance expectations through the company’s Performance Development Review (PDR) process and foster a motivated, valued, and engaged team.

Additionally, you will maintain and contribute to a succession plan as part of the wider Water Production team, supporting the ongoing development and resilience of the operation.

About you
You will be a great team player with strong leadership skills and a calm demeanour under pressure. You must be able to motivate and engage your team effectively. A full UK driving licence is required.

Qualifications
A qualification in the Management of Water Production is highly desirable. Training such as IOSH or NEBOSH is also highly desirable.
