  • Protect and enhance Thames Water’s reputation through effective stakeholder engagement.
  • Develop high-quality project briefs to support early contractor involvement.
  • Manage and challenge contractor performance to ensure delivery against agreed outcomes.

Location

Hybrid – Maple Lodge Sewage Treatment Works (2–3 days per week), with travel across the Thames Water region as required.

Requirement: Full UK driving licence.

  • A background in project management or operational delivery.
  • Strong commercial and contractual awareness.
  • Proven ability to manage and improve third-party performance.
  • Confidence in delivering constructive feedback and influencing stakeholders at all levels.
  • A proactive, solutions-focused mindset with the drive to add value.

Additional skills and experiences would be great to have/bring

  • Experience working on major projects or capital investment programmes.

What’s in it for you

  • Competitive salary from £56,000 to £67,000 per annum, depending on experience.
  • 26 days holiday per year, increasing to 30 with the length of service (plus bank holidays).
  • Job-Related Car Allowance.
  • Performance-related pay plan directly linked to both company and individual performance measures and targets.
  • Generous Pension Scheme through AON.
  • Access to a range of benefits to support health, wellbeing and finances, including annual health MOTs, physiotherapy and counselling, Cycle to Work schemes, shopping vouchers and life assurance.
