Summary
As a Senior Process Scientist, you will play a pivotal role in ensuring the safety, efficiency, and regulatory compliance of our drinking water treatment works across Kent and Sussex, based in Pembury and our West region based out of Farnborough. Serving as a primary technical authority within the Water Quality department, you will combine strategic oversight with hands-on process engineering to solve complex operational challenges, manage high-level risk, and champion continuous improvement.
In this hybrid leadership position, you will directly manage and empower a regional team of Process Scientists—fostering a culture of technical excellence, continuous professional development, and collaborative problem-solving. Working closely with Operations, Engineering, Regulatory Reporting, and DWSP teams, you will bridge the gap between day-to-day site performance, long-term asset strategy, and statutory compliance.

- Incident Management: Participate in the out-of-hours Duty Scientist standby rota to provide expert escalation support during water quality issues and incidents.
