Who We Are

We are a firm that values and respects our staff, fosters an environment that encourages learning and growth, and is committed to the success of our clients.

At PAE, we like to think of ourselves as a little bit different from most engineering firms. Here's why:

• We care intensely about envisioning and creating sustainable building systems and work every day to break new ground in the world of sustainable design.
• We have a close affinity to the visions of the architects we work with; we understand the need for beauty as well as practicality.
• We value creativity as much as we value precision.
• We understand that the visionary people we want to hire need to experience the world in order to change the world, and we work hard to support that need.
