Engineer Internship information

What is an engineer internship?

An Engineer Internship is a temporary position that allows students or recent graduates to gain practical experience in engineering. Interns work under the supervision of experienced engineers, contributing to real-world projects and tasks. This hands-on exposure helps interns apply classroom knowledge, develop technical and professional skills, and explore potential career paths in the engineering field. Internships are often paid and can lead to full-time job opportunities after graduation.

What are the key skills and qualifications needed to thrive as an engineer intern, and why are they important?

To thrive as an Engineer Intern, you need a solid understanding of engineering fundamentals, problem-solving skills, and relevant coursework in your field of study, often supported by enrollment in an accredited engineering program. Familiarity with technical tools such as CAD software, MATLAB, or project management platforms is typically expected. Strong communication, teamwork, and eagerness to learn help interns stand out and integrate effectively with professional teams. These skills and qualities are important for contributing meaningfully to projects, adapting quickly, and maximizing the learning experience during the internship.

What are some common challenges engineering interns face during their internship, and how can they overcome them?

Engineering interns often encounter challenges such as adjusting to real-world workflows, learning new software or technical tools quickly, and effectively communicating within multidisciplinary teams. To overcome these, it's helpful to proactively ask questions, seek feedback from mentors, and take initiative in learning about company processes. Building relationships with fellow interns and team members can also provide valuable support and insights, making the transition smoother and more rewarding.

Job description

Since 1996, RQ Construction, LLC. has been a leading player in Southern California's robust commercial and governmental Design-Build economy. We now have a national presence with current projects approaching $300M, spanning coast to coast, including Puerto Rico.

Our mission is "to provide our customers the best built environment while being the first choice of all stakeholders." Headquartered on the West Coast in Carlsbad, CA, we are a full-service Design-Build company. We offer management of projects throughout the United States, Guantanamo Bay, Cuba, and Puerto Rico, with our field operations' team members who work on location for each of our projects. We specialize in fast-track projects in new commercial construction for both public and private clients, with a primary focus in the Department of Defense market.

We are looking for an Internship candidate to join our Operations team on current projects in Puerto Rico. These opportunities will expose interns to entry-level management within the organization. Our assignments vary from field project operations to office support. Project assignments will require working on an active military base. Interns will be exposed to project management and field operations experiences that will help individuals see a possible future career within the field of construction. All work is performed on-site, whether on the jobsite or in the assigned office. Applicants must be pursuing their Mechanical Engineering Degrees.

EDUCATION & EXPERIENCE:

  • A High School Diploma (or GED equivalent) is the minimum education required for this position, though candidates enrolled in a Bachelor's Program (Construction Management, Mechanical Engineering, Civil Engineering, Business) will be given priority. A combination of equivalent work experience and training in the field may be qualifying.
  • Computer literacy (Microsoft Office, Internet, etc.) required.
  • Prior work experience within the construction industry strongly desired but not required.

We are an equal opportunity employer and all qualified applicants will receive consideration for employment without regard to race, color, creed, gender (including gender identity and gender expression), religion (all aspects of religious beliefs, observance or practice, including religious dress or grooming practices) marital status, registered domestic partner status, age, national origin or ancestry, physical or mental disability, medical condition (including cancer or a record or history of cancer, and genetic characteristics), sex (including pregnancy, childbirth, breastfeeding or related medical condition), genetic information, sexual orientation, veteran status, or any other basis or status protected by federal, state, or local law or ordinance or regulation.


All candidates considered for hire must provide evidence of identity and U.S. work authorization at the time of hire. Additionally, all candidates must successfully pass a drug screening and commercial criminal background check, including a stricter Department of Defense background check, for access to job site at military base (if applicable for position being hired for).
