Engineering is our purpose and our passion.

Do you want to belong to a group which prides themselves on providing world-class services to top-notch clients as part of a close-knit team of accomplished engineering professionals who, when they are not working together, might be playing in the lunchtime garage band or enjoying fun times together at a company picnic, pick-up basketball game, or family baseball outing? A company where you are more than a name on an org chart?

If so, then Commonwealth is the place for you. It’s a place to work, grow, learn, lead, and enjoy the many benefits that come from being 100% employee-owned and managed. Experience our invaluable, career-enhancing mentoring program or our college internship program and learn from our experts. No matter where you’re starting from or where you want to go, at Commonwealth the sky’s the limit.

We have an impressive engineering legacy, but that only matters by continuing the same commitment to engineering excellence, by meeting and exceeding the needs of our clients, and by providing the environment in which our employees, vendors, and those in the community around us can thrive.

"Thank you to Commonwealth for putting on the Summer Big Event for employees and our guests again this year. It was a wonderful evening at Comerica Park, despite the Tigers' loss - after all they played the reigning World Series Champs! We can't stop raving about the terrific picnic we had on the Pepsi Porch and I especially appreciated that our families were able to participate...nearly 200! I'm already looking forward to next year!"
