The Water Utilities Division is Mott Mac Donald’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.

Mott Mac Donald is a market leader in the UK water sector, being a key supplier to major water companies and delivering a wide variety of engineering and advisory projects in support to the challenges faced by the sector. Our Water Consultancy Division has ambitious growth plans in line with AMP8 investment needs and we are proud of our strong reputation in the industry which is allowing us to expand our business.

Having been appointed to a large UK water consultancy framework in 2024, we are looking for a Senior Associate Mechanical Engineer to support the delivery of our water and wastewater programmes.

You will have the opportunity to steer the technical direction of discipline related activities, working closely with our client and our other discipline leads. You will own the technical quality of the deliverables created by engineers/consultants and manage technical problem solving. You will also be expected to hold a key relationship with equivalent discipline leads for the client, leveraging this to help resolve technical issues and blockers.

The scale of investment required in AMP8 is both a significant challenge but a major opportunity to provide a long‑lasting legacy to our client and their region. It also requires new more efficient ways of delivering our services and for the successful candidate to demonstrate their ability to identify and implement innovations that maintain delivery to programme and commercial targets.

• Provide technical mechanical expertise across our programmes of water and wastewater engineering.
• Perform feasibility, outline, and detailed mechanical design.
• Accountable for checking and the overall technical quality of the deliverables created by the mechanical team.
• Work closely with other disciplines, contributing to deliverables including technical reports, drawings, models, plant and equipment specifications, schedules, design risk assessments, and cost and program estimates.
• Develop and nurture sound relationships with our clients.
• Co‑ordinate mechanical resources across the framework alongside resource managers, project managers and project technical leads.
• Line manage, track and encourage the continuous development of mechanical discipline staff.
