Expression of Interest - Project Manager – Water Sector in Cardiff

This is an Expression of Interest to join Stantec as a Project Manager within our Water sector. At Stantec, we’re passionate about shaping a better future for the communities we serve – and our Water team sits at the heart of that mission. We’re now looking for experienced Project Managers with a strong background in the water sector to help us deliver the projects that keep our water systems resilient, sustainable, and ready for the future.

With hybrid working and offices across the UK, you’ll have the flexibility to work in a way that supports collaboration, innovation, and balance. Our teams work across the full water cycle – from water resources and treatment to wastewater networks, supply resilience, and flood mitigation.

As a Project Manager, you’ll play a central role in bringing complex, multidisciplinary projects to life. From early planning through to delivery, you’ll keep projects on track – managing programme, cost, quality, and communication in a way that builds confidence with clients and motivates those around you. You’ll take the lead on project documentation, contracts, and commercial performance, always with an eye on risk, opportunities, and continuous improvement.

Strong relationships matter here, and you’ll be a key link between internal teams and clients – helping everyone stay aligned and focused on delivering great outcomes. Safety will be a core part of your role. You’ll promote a positive HSSE culture and make sure teams have the support, training, and clarity they need to work safely and effectively. You’ll also have the chance to support wider business development activities – contributing to proposals and helping to identify opportunities where our expertise can make a real difference.

You’ll bring proven project management experience in the water sector and a track record of delivering multidisciplinary or infrastructure projects. You’re organised, detail‑focused, and clear in your communication – clients trust you, and teams enjoy working with you. Curiosity is important to us; we value people who ask questions, explore new ideas, and look for ways to improve how we work and deliver.

You’ll bring solid experience delivering projects within the water sector and the confidence to lead multidisciplinary teams. A recognised project management qualification – such as the APM PMQ – is an advantage, but what matters most is your proven ability to deliver, your sound judgement, and the way you build trust with clients and colleagues.

You’ll join a friendly, knowledgeable, and ambitious team working on projects that genuinely matter. You’ll be supported to grow your skills, shape your career, and contribute to work that has a meaningful impact on communities across the UK. If you’re looking for a role where your expertise, ideas, and curiosity will be welcomed – and where you can help deliver the future of water – we’d love to speak with you.
