Commissioning Engineer Jobs in Illinois: Frequently Asked Questions
How do you become a commissioning engineer in Illinois?
Most commissioning engineers in Illinois enter through a four-year engineering degree in electrical, mechanical, or controls engineering, then gain field experience working under a licensed professional engineer. Illinois does not require a state-specific commissioning license, but obtaining a Professional Engineer license through the Illinois Department of Financial and Professional Regulation strengthens long-term career standing. Industry credentials like ASHRAE's Commissioning Process Management Professional or NEBB certification are recognized by many Illinois employers and can accelerate hiring.
How much do commissioning engineers make in Illinois?
Commissioning engineers in Illinois earn a median of about $111,930 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $58,920 for the lowest 10% to over $168,770 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire commissioning engineers in Illinois?
Employers hiring commissioning engineers in Illinois right now include CAI, Jobot, and Amazon, based on current listings on Migrate Mate as of November 2026. Illinois's concentration of large industrial manufacturers, commercial construction contractors, and energy infrastructure companies means hiring activity tends to be steady year-round rather than seasonal.
Which Illinois cities have the most commissioning engineer jobs?
Chicago, Plainfield, and Romeoville have the most commissioning engineer openings in Illinois. Chicago drives volume through its dense commercial construction and building automation market, while suburban corridors like Schaumburg, Naperville, and Downers Grove house major engineering firms and manufacturers that rely on commissioning staff for ongoing facility and industrial work.
Are there remote commissioning engineer jobs in Illinois?
Yes, but they're rare. Commissioning engineering is fundamentally a hands-on, site-based role that requires physical presence to start up and verify equipment. About 100% of commissioning engineer openings tied to Illinois are remote or hybrid as of November 2026, and those roles typically involve documentation review, pre-commissioning planning, or project coordination rather than direct field work.
How can I get hired as a commissioning engineer in Illinois with little or no experience?
The most realistic entry path is starting as a field service technician or controls technician with a large Illinois contractor, then moving into commissioning as you accumulate system startup experience. Companies like Johnson Controls and Siemens run associate field engineer programs out of their Illinois offices that are designed for candidates without prior commissioning experience. A degree in electrical or mechanical engineering, combined with any hands-on lab or co-op work involving building systems or PLCs, gives candidates a measurable edge when applying to these programs.
