Engineering Intern - Summer 2026 (Denver, CO; Lebanon, OR; ...)
General Purpose:
McCarl’s Technical Services is seeking motivated engineering students—at least juniors in an accredited engineering program—who are eager to apply classroom knowledge to real-world EPC (Engineering, Procurement & Construction) project work. As an Engineering Intern, you’ll support multidisciplinary teams working on heavy industrial projects. You’ll gain hands-on experience with design development, engineering calculations, field verification, and cross-discipline coordination.
Interns will be assigned responsibilities aligned with their current academic discipline (Civil/Structural, Mechanical, Electrical, or Chemical/Process) and are not expected to perform engineering work outside their field of study.
This role is ideal for students who want exposure to the full project lifecycle and who enjoy solving practical engineering problems in a collaborative environment.
Essential Duties and Responsibilities:
Note: The responsibilities below apply only to interns pursuing the corresponding engineering discipline.
