Build your civil engineering experience with Merrick & Company as a paid Summer 2027 Civil Water Wastewater Engineer Intern in our San Antonio, Texas office. This internship is a great opportunity for a college or graduate-level Civil Engineering student to contribute to meaningful projects while learning alongside experienced engineers.
Merrick’s summer internship program offers meaningful, hands-on experience for students. Designed as a shorter-term, exploratory experience, internships allow students to apply what they’re learning in school while gaining exposure to real projects, professional collaboration, and day-to-day life at an employee-owned company.
The summer internship has a commitment of approximately mid-May through mid-August 2027.
The intern will be exposed to a variety of engineering tasks including wastewater and potable water systems design, the preparation of drawings and details, process models, cost estimates, operations and maintenance manuals, study and design reports, and other work products.
The intern will gain experience in collaborating with other disciplines, interfacing with clients and contractors, following schedules and budget commitments, working independently, communicating, and problem solving.

At Merrick, employee ownership drives us as we work alongside our clients to develop the right solutions to better our world. We’re motivated by a need to do the right thing and be the best we can be—and we make decisions based on that, not the bottom line. As employee owners, we’re empowered to find the solutions that have a positive impact on our communities, our company, and our world.
We’re an employee-owned, multi-discipline professional engineering, architecture, surveying, geospatial, and science and technology solutions firm. We serve domestic and international clients in the aerospace; infrastructure; nuclear; energy, manufacturing, and bioprocessing; and life sciences markets.
