Chemical Engineer Jobs in Illinois: Frequently Asked Questions
How do you become a chemical engineer in Illinois?
You become a chemical engineer in Illinois by earning an ABET-accredited bachelor's degree in chemical engineering, which most employers treat as the baseline requirement for entry-level roles. Illinois does not require a state license to work as a chemical engineer in industry, but those moving into consulting, public infrastructure, or roles where you sign off on designs should pursue Professional Engineer licensure through the Illinois Department of Financial and Professional Regulation by passing the FE and PE exams.
How much do chemical engineers make in Illinois?
Chemical engineers in Illinois earn a median of about $121,560 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $79,120 for the lowest 10% to over $176,110 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire chemical engineers in Illinois?
Employers hiring chemical engineers in Illinois right now include WSP, POLYNT, and Honeywell, based on current listings on Migrate Mate as of August 2026. Illinois's dense concentration of refining, specialty chemical, pharmaceutical, and food manufacturing facilities means hiring activity is spread across both large corporate campuses in the Chicago suburbs and major industrial sites along the I-55 and Calumet corridors.
Which Illinois cities have the most chemical engineer jobs?
The cities with the most chemical engineer openings in Illinois are Chicago, Effingham, and Metropolis. The Chicago metro dominates because it anchors the region's pharmaceutical, food science, and specialty chemical headquarters, while Joliet and the broader Calumet industrial area draw significant demand from petroleum refining and bulk chemical manufacturing facilities that require large engineering staffs.
Are there remote chemical engineer jobs in Illinois?
Yes, but they're rare. Chemical engineering is fundamentally a hands-on discipline tied to physical plant operations, lab environments, and on-site process oversight, so fully remote roles are the exception rather than the rule. About 67% of chemical engineer openings tied to Illinois are remote or hybrid as of August 2026, and those positions are most often in regulatory affairs, technical sales support, or process modeling roles that don't require direct plant access.
How can I get hired as a chemical engineer in Illinois with little or no experience?
The most realistic entry path is applying directly to new-graduate rotational or associate engineer programs at large Illinois chemical and manufacturing employers, which regularly recruit from University of Illinois, Illinois Institute of Technology, and Northwestern. Look for process technician or junior process engineer titles as lateral entry points, since many Illinois facilities promote from operations experience. Completing your FE exam before graduating and developing hands-on skills through co-ops or internships at Illinois facilities gives you a concrete edge in a competitive candidate pool.
Where can I find and apply to chemical engineer jobs in Illinois?
You can find and apply to chemical engineer jobs in Illinois on Migrate Mate, which lists current Illinois openings from employers actively hiring. Find roles that fit your experience and specialty and apply directly from the listing.
