Build Something That Matters This Summer
As an Engineering Intern at MacLean-Fogg, you will apply what you are learning in the classroom to real manufacturing challenges. You will work alongside engineers, operators, quality professionals, and maintenance teams to understand how products are made and help improve the products and processes behind them.
You will take ownership of a meaningful engineering project with guidance from an experienced team. Depending on your assignment, you might investigate a quality issue, reduce scrap, improve a process, support automation, develop a design, or evaluate material performance. At the end of the program, you will present your project, results, and recommendations to facility leadership.
One application connects you with the engineering internship opportunities available at this manufacturing facility. Tell us which areas interest you in the application. We will consider your interests, skills, and experience alongside available projects and business needs.

Engineering Intern Jobs in Illinois: Frequently Asked Questions
How do you become a engineering intern in Illinois?
Becoming an engineering intern in Illinois starts with enrollment in an ABET-accredited engineering program at a university such as the University of Illinois Urbana-Champaign, Illinois Tech, or Northwestern. Illinois does not require a state license for internship work, but candidates pursuing civil or structural engineering should be aware that the Illinois Department of Financial and Professional Regulation oversees Professional Engineer licensure, and beginning the Fundamentals of Engineering exam early strengthens your candidacy significantly.
Which companies hire engineering interns in Illinois?
Employers hiring engineering interns in Illinois right now include Shure, State of Illinois, and Burns & McDonnell, based on current listings on Migrate Mate as of September 2026. Illinois's concentration of manufacturing headquarters, national laboratories such as Argonne, and major infrastructure firms means intern roles appear across a wide range of engineering disciplines throughout the year.
Which Illinois cities have the most engineering intern jobs?
The cities with the most engineering intern openings in Illinois are Chicago, Niles, and Darien. Chicago dominates due to its density of corporate headquarters, engineering consultancies, and technology firms, while Peoria reflects Caterpillar's global operations and supplier network, and Rockford draws from its strong aerospace and precision manufacturing base.
Are there remote engineering intern jobs in Illinois?
Yes, but they're rare. About 60% of engineering intern openings tied to Illinois are remote or hybrid as of September 2026, reflecting the hands-on, lab-based, or plant-floor nature of most engineering internship work. The roles most likely to offer remote or hybrid arrangements are in software engineering, data analysis, and systems design rather than civil, mechanical, or manufacturing disciplines.
How can I get hired as a engineering intern in Illinois with little or no experience?
The most realistic entry path is applying to structured intern programs at large Illinois employers before completing your junior year. Caterpillar, Abbott, and Exelon all run rotational intern cohorts that explicitly target students with no prior industry experience. Building a portfolio of class projects, participating in engineering competitions through Illinois university chapters of ASME or IEEE, and passing the Fundamentals of Engineering exam early all give candidates a measurable edge when applying to those competitive programs.
Where can I find and apply to engineering intern jobs in Illinois?
You can find and apply to engineering intern jobs in Illinois on Migrate Mate, which lists current openings from employers actively hiring across the state. Search the listings for roles that match your discipline and location, then apply directly to the ones that fit your background and availability.
