We have an exciting opportunity for you to join Thames Water as a Technical Process Lead.

The job pays between £39,140-£52,954 depending on knowledge and experience. 

What you’ll be doing

This is a unique role, and you will be involved with multiple projects and activities that reduce operational expenditure working closely with local teams and other departments to identify, plan and deliver the efficiencies and improvement projects. No two days are the same, and you will gain experience and broaden your company knowledge working on initiatives independently and/or with other specialist team members.

  • Good organisational, communication and interpersonal skills are also key to this role, as you will be liaising with senior managers, colleagues, and front-line operatives as well as working across other departments
  • You will be a self-starter, seeking new ways of working and betterment, and you will be able to take the initiative and not rely upon close supervision and guidance. You will work in a logical and analytical manner, able to articulate complex subjects in an appropriate manner for various audiences
