CONTRIBUTE TO A HEALTHIER ENVIRONMENT, ONE PROJECT AT A TIME

At Riparia Environmental, we believe that expertise, customized solutions, and client-focused service starts with a passionate and skilled team. Our team doesn’t just work outdoors—we thrive in it. Whether restoring natural habitats or managing stormwater systems, our crew isn’t afraid to get their hands dirty. Hard work, teamwork, and a love for the environment drives everything we do.

As part of our team, you’ll work with a group of professionals to solve complex environmental challenges. If you’re ready to roll up your sleeves and make a real impact, we’re looking for people who share our passion for the outdoors and commitment to excellence.

Our employees also benefit from the support of our parent company, MacKay Sposito, with a comprehensive list of shared services—including Human Resources, IT, Accounting, Business Development, Fleet, and Communications—allowing you to focus on what you do best: providing exceptional service to our clients.
