Engineering services represent roughly $262 billion in annual revenue in the US alone, according to the US Department of Commerce’s Select USA program. More than 75,000 firms contribute to this market. Even though there are a few industry giants, IBISWorld reports that not even the top engineering firms have more than a 5% market share.
There are four main branches of engineering—civil, mechanical, electrical, and chemical—with many large firms providing services in more than one area. Because engineering goes hand-in-hand with architecture and construction, the biggest engineering firms often have full-scale architecture and construction divisions.
Below, we’ve listed 30 of the top engineering firms in the US, based on revenue figures reported by ZoomInfo. This list represents firms that focus primarily on engineering versus the larger full-service conglomerates. We looked at the largest construction companies and top architecture firms separately.

What Makes a Billion-Dollar Engineering Firm?
Scaling to a billion dollars isn’t easy. Aside from the five firms that we looked at above, only 13 others on this list have reached more than 10% of this goal. And there are 75,000 more organizations trying to secure a bigger market share.
So what can other high-growth firms learn from these billion-dollar giants on their quest to scale?
It takes a global footprint.
All of these firms operate in more than one country. In fact, three out of the top five don’t even have their headquarters in the US. Although the US engineering services market is healthy and represents roughly 30% of the total, the global market opportunity is three times bigger.
Offer multiple service lines.
One thing is clear from the top five engineering firms on this list—you can’t grow to a billion dollars by specializing in one service line. They all offer an array of capabilities across numerous sectors. If your firm’s project portfolio is concentrated in one or two areas of specialty, or your clients are all in the same industry, consider diversifying services.
Constant innovation is non-negotiable.
Innovation is essential for any business trying to gain a competitive advantage, but it’s particularly important for engineering firms. Engineers are the world’s biggest problem-solvers. Because the world is constantly evolving, so too are the challenges we face. If you want to be the best in class, you must be committed to continually finding new and better solutions.
Technology is a key differentiator.
The top engineering firms lead with a technology-centric approach. This isn’t just about technical consulting. It’s also about what technologies are powering your organization. The best firms use technology like business intelligence tools and resource management software to build more scalable, intelligent, and profitable organizations.
The future for the global engineering services market is bright. It’s expected to reach $2 trillion by 2026. With the right recipe and approach, there are still plenty of opportunities for up-and-coming firms to secure their positions as top engineering companies.
