Summer Civil Engineering Internship - Drainage, Stormwater & Utilities

Miller Gray is a locally owned, growing civil engineering firm based in Austin, and we are looking for a Civil Engineering Intern to join our team for Summer 2026
. This is a paid internship designed for a civil engineering student in their junior year who is eager to gain hands‑on experience, learn from experienced engineers, and explore a career in public infrastructure design.

Our work focuses primarily on public infrastructure projects for municipalities and counties across Central Texas
, with an emphasis on hydraulics and hydrology, stormwater management, drainage, flood control, and water quality
. This internship will also provide exposure to water, wastewater, and utility/pipeline design projects
, giving students the opportunity to build a broad technical foundation while working on real-world projects.

At Miller Gray, we believe future engineers learn best through meaningful project experience, direct mentorship, and a collaborative team environment. As a small and growing local firm, we offer interns the chance to work closely with senior staff, ask questions, build practical skills, and see how engineering solutions make a direct impact in the communities we serve.

• Support engineering analyses and design for stormwater, drainage, flood control, and water quality projects
