Process Mechanical Engineering Intern - Water (Summer 2027)

Location: Phoenix, AZ, United States

Learning begins in the classroom but there’s no better place to gain real-world experience than with Stantec. Interns are an integral part of our teams, working to solve some of the world's most complex challenges.

As an intern, you’ll work alongside our experienced practitioners and with our clients and communities. This hands-on experience will equip you with practical skills, build your network, and provide opportunities that set you up for success.

Many of the world’s top engineers and scientists come together in our Water business because they view a community’s interaction with water a bit differently—as a single holistic system, rather than unconnected networks divided by jurisdictional boundaries. Working throughout the hydrologic cycle, we are delivering sustainable solutions to make sure water is where it should be and available when needed. Our experts guide our work with scientific rigor, an innovative spirit, and a vision for growth. Every day, we help communities improve, reuse, and protect this precious resource for future generations. Grow with us, H2O+U.

Do you want to be part of a collaborative team that puts people first, lives its corporate values, and works on some of the most challenging water projects in the world? Join us.
