Specialty Engineering and Consulting Intern - CU Boulder

General Responsibilities:

Terracon is a specialty engineering consulting firm with expertise in geotechnical engineering, environmental consulting, construction materials testing and inspections, and facilities services with a fun and exciting intern program. Terracon supports public and private agencies, civil engineers, architects, developers, owners, and other partners throughout the project lifecycle, from site selection through design, construction, and asset management. Work alongside industry professionals and CU Boulder alumni while building practical skills on projects that support infrastructure, environmental stewardship, and community impact.

The internship program emphasizes mentorship, early-career development, and potential pathways to full-time opportunities. Opportunities are available across Terracon’s 200+ offices nationwide. Applicants may identify a preferred location and are encouraged to indicate interest in additional offices if open to relocation.

We are seeking students interested in Summer 2027 internships supporting one or more of these specialized service lines. Internships generally run May through August. Co-op opportunities may run May through December. Interns work alongside experienced engineers, scientists, consultants, and technicians on active projects. The experience may include field investigations, testing and inspection services, data collection and analysis, technical problem-solving, project delivery, and client-focused consulting.

Each intern is paired with a leader or mentor who supports technical skill development, career exploration, and professional growth.

You will also have the opportunity to participate in a cohort. The cohort is a way for you to connect with other interns across the company and learn about their experiences. This is also a great way for you to start building your professional network!

Our summer concludes with a fun and engaging summit where you will meet leaders, learn more about how to grow a career at Terracon, and build stronger relationships with your peers.
