Structural Intern - Water Wastewater

Structural Engineering Internship | Summer 2026

Start Building Your Career Before You Graduate. At HR Green, we don’t believe internships should mean busywork or shadowing from the sidelines. We believe in real projects, real mentorship, and real impact — the kind that helps you figure out not just what you want to do, but where you want to grow.

Our mission is simple and meaningful: Building Communities. Improving Lives. For more than 110 years, we’ve partnered with communities across the country to design infrastructure that people rely on every day — clean water, safe roads, sustainable development, and resilient systems. In 2025, we were proud to be ranked #168 on ENR’s Top 500 Design Firms and recognized as a Best Place to Work — but what matters most to us is the people who make that work possible.

What You’ll Experience as an HR Green Intern

Our paid Civil Engineering Internship is designed for students who want hands-on experience, not just resume lines. During this Structural - Water Wastewater internship opportunity you will:

• Assist with structural analysis and design tasks for water and wastewater facilities, including concrete and steel structures, under the guidance of a lead structural engineer.
• Support the development of structural calculations, specifications, and design drawings using structural and CADD software.
• Participate in project coordination and occasional site visits to gain exposure to water and wastewater facilities and construction activities.

You won’t be doing this alone. Every intern is:

• Paired with a new-hire buddy for day-to-day guidance
• Supported by experienced engineers who want to teach, mentor, and invest in you
• Invited to office events, networking opportunities, and team activities that help you feel like part of the firm — not “just an intern”

You should be:

• Enrolled in an accredited Civil, Environmental, or related Engineering program
• Curious, motivated, and eager to learn
• Comfortable with basic office software (Word, Excel, etc.)
