Job description

Senior Mechanical Engineer - Water Sector, Inverness.

Scottish Water is about to invest £8.1bn in its network, the biggest programme in its history. Stantec is one of just two Primary Designers chosen to deliver it.

This landmark partnership, which potentially extends to 2039, secures meaningful work from our Inverness office. Not one project. Not one framework cycle. A pipeline of water and wastewater schemes that will shape how Scotland lives for a generation. This major framework success anchors our exceptional performance across the UK for the AMP8 regulatory cycle, where we have secured exciting new project wins and solidified our standing as the number 1 design consultancy in the regulated water sector.

Most engineers get one programme like this in a career. We're building the team now, and the people who join early get to shape how it runs.

You will produce and review technical calculations, specifications, schedules and engineering documentation, and work closely with Project Managers and multidisciplinary teams to deliver integrated solutions.

You will support site investigations, design reviews and construction activities where required, and build strong working relationships with clients, contractors and delivery partners.

You will also provide technical guidance and mentoring to junior engineers, helping to strengthen our Mechanical Engineering capability.
