About the Division

The Water Utilities Division is Mott MacDonald’s centre of excellence for responding to the UK and Ireland's water and wastewater challenges. The work we do is at the forefront of ensuring safe water supplies for future generations, preventing urban flooding, and improving the health of our rivers and coastal environments. Our multi-disciplinary teams provide a variety of services throughout the full project life cycle, from advisory services and feasibility studies to outline and detailed design. Together, we deliver best-in-class solutions to our clients while offering diverse and technically stimulating opportunities to our people.

Overview of the role

We work on a vast range of design projects covering, for example:

  • Water treatment
  • Water distribution and storage
  • Wastewater drainage and recycling
  • Desalination

Our clients include most UK water utility companies and many other governmental organisations and private companies in the UK and overseas. We cover all phases of the project lifecycle from feasibility studies through detailed design, construction support, and commissioning to handover. This offers fantastic opportunities to get involved in diverse and technically challenging work and support professional development.

To help us to meet the growing needs of our clients, we have several positions for experienced civil engineers in water and wastewater who will thrive:

  • Working across multiple UK and Ireland water companies
  • Being part of multi-disciplinary design teams in project delivery
  • Delivering excellence everyday
  • Preparing design submissions to ensure compliance with contract requirements
  • Undertaking studies, concept, preliminary and detailed design
  • Collaborating with clients and other stakeholders

This is great opportunity to make a difference. You have the skills, now use them at a company that values a different perspective. Being employee owned means we can choose our own direction and focus on what we believe is important for our clients, our people and the communities where we work and live.

Candidate specification

Essential:

  • Civil engineering degree
  • Water and/or wastewater engineering design experience
  • Excellent verbal and written communication skills
  • Understanding of the importance of prioritising health, safety, and environmental issues
  • Proactive approach, with an ability to adapt to changing scenarios

Desirable:

  • Working towards Chartership
  • Strong digital capability
  • Project Management experience is not essential but previous experience or a desire to develop these skills would be beneficial

UK Immigration

Mott MacDonald Ltd. are not currently offering sponsorship to candidates under the Skilled Worker visa route in the UK. This decision is as a consequence of the changes made to the Skilled Worker route by the UK Government in April 2024. We continue to welcome applications from candidates who are eligible for alternative immigration routes in the UK, that do not require sponsorship as a Skilled Worker now or in future.
