Position Summary
Join the App Engineering team as an App Engineering Intern and help build the modern, AI-enabled business applications that Hollister teams use every day. Working within our full stack engineering team, you will design, develop, test, and ship web and mobile applications, APIs, and integrations, using AI both inside the products you build and as a daily accelerator in how you build them. The role combines hands-on full stack development with AI-assisted engineering, user-centered design, and the engineering discipline required in a regulated medical device environment.
This internship is designed for talented undergraduate and master’s candidates who are eager to apply software engineering and AI skills to real business problems. Reporting to Saad Patel within the Digital Platforms & App Engineering function, the intern will work closely with full stack developers, integration engineers, AI engineers, architects, and business stakeholders while learning how an application moves from an idea and a prototype to a secure, supported, production release.

Search Engineering Intern Jobs in IllinoisEngineering Intern Jobs in Illinois: Frequently Asked Questions
Which companies sponsor visas for engineering interns in Illinois?
Large Illinois employers with established intern sponsorship programs include Caterpillar, Abbott Laboratories, Motorola Solutions, Boeing, and Exelon. Chicago-area consulting and tech firms such as Accenture and Zebra Technologies also hire engineering interns with visa support. Sponsorship is most consistent at companies with formal rotational intern programs and dedicated HR immigration infrastructure, typically larger organizations rather than early-stage startups.
Which visa types are most common for engineering intern roles in Illinois?
Most international engineering interns in Illinois work under F-1 OPT or CPT, which allows students enrolled at U.S. universities to work for a qualifying employer without a separate employer-sponsored visa petition. STEM OPT extensions give graduates of engineering programs up to three additional years of work authorization. The H-1B visa is generally not available for internships directly, as it requires full-time specialty occupation employment and applies only after graduation.
Which cities in Illinois have the most engineering intern sponsorship jobs?
Chicago and its suburbs, particularly Schaumburg, Deerfield, and Lisle, account for the largest share of engineering intern roles in Illinois given the concentration of Fortune 500 headquarters and regional offices. Peoria is a secondary hub driven by Caterpillar's global operations. Urbana-Champaign sees intern activity tied to the University of Illinois ecosystem, including startups and research-adjacent employers that recruit on campus.
How to find engineering intern visa sponsorship jobs in Illinois?
Migrate Mate filters engineering intern roles specifically by visa sponsorship availability, so you can search Illinois without sifting through positions that don't support international candidates. Roles listed on Migrate Mate are tagged for sponsorship, which is particularly useful for F-1 students on OPT or CPT who need to confirm employer eligibility quickly. Filtering by Illinois and the engineering intern category narrows results to the Chicago metro, Peoria, and other active hiring markets in the state.
Are there state-specific factors that affect visa sponsorship for engineering interns in Illinois?
Illinois has a strong university pipeline, with the University of Illinois Urbana-Champaign, Northwestern, and Illinois Institute of Technology consistently producing international engineering graduates who enter the intern market on F-1 status. Employers in Illinois manufacturing and defense sectors, such as those in the Peoria and Rockford corridors, are accustomed to sponsoring international talent. However, sponsorship availability still varies by company size, and smaller Illinois employers may lack the legal and HR resources to support visa paperwork.
What is the prevailing wage for sponsored engineering intern jobs in Illinois?
U.S. employers sponsoring a visa must pay at least the prevailing wage, which is what workers in the same role, area, and experience level typically earn. The Department of Labor sets this rate to make sure companies aren't hiring foreign workers simply because they'd accept lower pay than a U.S. worker. It varies by job title, location, and experience. You can look up current prevailing wage rates for any occupation and location using the OFLC Wage Search page.
