Brennan offers careers on, around, and below the water for people ready to grow, work safely, and contribute to complex marine, environmental, and energy infrastructure projects.
A Team That Respects & Supports One Another
Brennan employees do things every day that many people never thought were possible. We build in active waterways, restore sensitive environments, inspect underwater infrastructure, repair dams, support energy facilities, manage harbor operations, and solve complex problems in difficult conditions.

Our culture is built around people who take pride in their work and care about the team beside them. We value honesty, respect, accountability, innovation, and the willingness to keep learning. When our people grow stronger, Brennan grows stronger.
