Security Software Engineer Jobs in Illinois: Frequently Asked Questions
How do you become a security software engineer in Illinois?
Becoming a security software engineer in Illinois starts with a bachelor's degree in computer science, software engineering, or cybersecurity from an accredited program, many of which are offered at Illinois universities including the University of Illinois and DePaul. Illinois has no state-issued license specific to this role, so employers rely on industry certifications like CISSP or CEH alongside a portfolio of security engineering work to assess candidates.
How much do security software engineers make in Illinois?
Security software engineers in Illinois earn a median of about $132,110 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $80,980 for the lowest 10% to over $194,740 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire security software engineers in Illinois?
Employers hiring security software engineers in Illinois right now include Pinterest, Northern Trust, and AbbVie, based on current listings on Migrate Mate as of September 2026. Illinois's concentration of financial services firms, defense contractors, and enterprise technology companies in and around Chicago makes it one of the more active states for security engineering roles at mid-size and large organizations.
Which Illinois cities have the most security software engineer jobs?
Chicago, Round Lake, and North Chicago have the most security software engineer openings in Illinois. Chicago dominates because of its dense concentration of financial technology firms, healthcare systems, and enterprise software companies, while Naperville and Schaumburg draw strong hiring volumes from the corporate headquarters and technology campuses that line the I-88 corridor west of the city.
Are there remote security software engineer jobs in Illinois?
Yes, and more than most fields. About 100% of security software engineer openings tied to Illinois are remote or hybrid as of September 2026, reflecting how much of the work centers on code review, security tooling, and cloud platform configuration rather than on-site infrastructure. Application security and DevSecOps roles tend to be the most remote-friendly specialties within this field.
How can I get hired as a security software engineer in Illinois with little or no experience?
The most realistic entry path is a junior or associate security engineer role, often listed under titles like security analyst or software engineer with a security focus, at Illinois financial services firms or managed security service providers in the Chicago metro. Building a portfolio through open-source contributions, Capture the Flag competitions, or a home lab demonstrating hands-on vulnerability work gives candidates a clear edge. CompTIA Security+ is widely accepted by Illinois employers as an entry-level credential that substitutes for experience in competitive screening.
Where can I find and apply to security software engineer jobs in Illinois?
You can find and apply to security software engineer jobs in Illinois on Migrate Mate, which lists current Illinois openings across Chicago, Naperville, and the broader state. Find roles that fit your experience and specialization and apply directly.
