Many Illinois employers also value familiarity with Illinois EPA site remediation and permit programs from day one.
How much do environmental engineers make in Illinois?
Environmental engineers in Illinois earn a median of about $107,990 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $71,990 for the lowest 10% to over $153,150 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire environmental engineers in Illinois?
Employers hiring environmental engineers in Illinois right now include Sargent & Lundy, Langan Engineering and Environmental Services, and AECOM, based on current listings on Migrate Mate as of November 2026. Illinois's active industrial base, extensive brownfield inventory, and large municipal water systems keep demand broad, drawing both national consulting firms and local specialty contractors.
Which Illinois cities have the most environmental engineer jobs?
Chicago, Elwood, and Normal have the most environmental engineer openings in Illinois. Chicago dominates because of its concentration of large consulting firms, industrial facilities, and municipal infrastructure projects, while Rockford and the East St. Louis area generate steady demand from manufacturing remediation and regional utility work.
Are there remote environmental engineer jobs in Illinois?
Yes, but they're rare. About 50% of environmental engineer openings tied to Illinois are remote or hybrid as of November 2026, reflecting the field's heavy reliance on fieldwork, site investigations, and in-person regulatory meetings. The portions of the role most suited to remote work are report writing, data analysis, and regulatory document review.

The most realistic entry path is an internship or junior engineer role at one of Illinois's large environmental consulting firms, many of which recruit directly from University of Illinois, Northwestern, and Illinois Institute of Technology. Look for entry-level site assessment or remediation assistant positions at firms supporting Illinois EPA brownfield programs. Passing the Fundamentals of Engineering exam early and building GIS or environmental sampling skills strengthens a new-grad application considerably.
