Net Engineer Jobs in Illinois: Frequently Asked Questions
How do you become a net engineer in Illinois?
Illinois does not require a state-issued license specifically for net engineers, so the path runs through education and vendor certifications. Most employers expect at least a bachelor's degree in information technology, computer science, or a related field. Entry candidates who hold a CompTIA Network+ or a Cisco CCNA before applying stand out significantly in the Illinois market, where enterprise and financial-sector employers treat those credentials as a practical hiring filter.
How much do net engineers make in Illinois?
Net engineers in Illinois earn a median of about $132,790 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $81,630 for the lowest 10% to over $201,190 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire net engineers in Illinois?
Employers hiring net engineers in Illinois right now include RLI, Chamberlain, and Northern Trust, based on current listings on Migrate Mate as of October 2026. Illinois's concentration of Fortune 500 headquarters, major telecommunications carriers, and large healthcare systems creates a particularly broad and sustained demand for networking talent across the state.
Which Illinois cities have the most net engineer jobs?
Peoria, Chicago, and Oak Brook account for the most net engineer openings in Illinois. Chicago leads because of its density of financial institutions, enterprise technology companies, and carrier-grade network infrastructure, while Naperville and Schaumburg generate strong suburban volume from the large corporate campuses and regional operations centers concentrated along the I-88 technology corridor.
Are there remote net engineer jobs in Illinois?
Yes, but they are less common than in purely software-focused roles because net engineering frequently requires hands-on work with physical hardware and on-site infrastructure. About 100% of net engineer openings tied to Illinois are remote or hybrid as of October 2026, and the positions most likely to offer remote flexibility are those centered on cloud networking, network monitoring, and security operations rather than data-center or campus infrastructure work.
How can I get hired as a net engineer in Illinois with little or no experience?
The most realistic entry path is a help desk or IT support role at one of Illinois's large healthcare systems, universities, or financial-services firms, where internal mobility into networking teams is well established. Earning a CompTIA Network+ or Cisco CCNA before applying signals technical readiness that substitutes for work history. Community colleges across the Chicago area, including Moraine Valley and College of DuPage, offer network technology programs that Illinois employers actively recruit from for associate-level positions.
