  • Change Management: Ensure all projects are business-ready and changes are effectively embedded across the organisation.
  • Continuous Improvement: Lead initiatives to improve internal processes and the customer journey, using learning from previous incidents to prevent recurrence.

  • A genuine passion for improving environmental outcomes and customer satisfaction.

  • Ability to influence and work collaboratively across all levels of the organisation.
  • Lean Six Sigma qualification or demonstrable experience applying continuous improvement methodologies.

  • Experienced in delivery of sewer flooding mitigation solutions would be beneficial however not essential.

  • Performance-related pay plan directly linked to company performance measures and targets.
  • Generous Pension Scheme through AON.
  • Generous Paternity Leave, including 4 weeks paid and an optional 2 weeks unpaid.
