At Brennan, our people are our top priority. We support complex construction projects, solve difficult problems, and help shape the future of marine infrastructure and environmental services. We are growing our presence in the St. Louis market and are looking for Project Managers who want more than just another PM role. This is an opportunity for someone who enjoys complex work, wants ownership and visibility, and values being part of a team where they are supported instead of left on an island. As a family-owned, relationship-driven company, we take pride in open communication, collaboration, and building a culture where people are trusted and empowered to grow. Join our team and help us continue building Brennan’s presence in St. Louis while creating a rewarding career with people who care deeply about their work and each other.
