San Antonio's largest engineering firms

The largest engineering firms in San antonio employ over 450 licensed engineers locally in 2024. Firms have local offices in the San Antonio-New Braunfels MSA. The online version of this ranking expands beyond what appears in print; another 38 engineering firms are included in our digital rankings, in addition to the 20 featured in this week's print edition. This week's List is part of a shift in our research methodology and philosophy in 2025, one that will emphasize more data and context for readers while better coordinating the resources available to us and our 46 sister publications under the American City Business Journals flag. We anticipate this effort will identify thousands of new local records — and cumulatively, tens of thousands of new businesses across ACBJ's footprint — this year alone. Information on The List was obtained through San Antonio Business Journal research or supplied by individual firms through questionnaires that SABJ could not independently verify. In case of ties, firms are ranked by total employment and then listed alphabetically if ties remain. Additionally, companies that did not respond to employment surveys but were still included on this year's List are sorted by estimated total employment figures derived from SABJ archives; annual filings with the U.S. Department of Labor; and other firm-specific resources.
