System Administrator Jobs in Colorado: Frequently Asked Questions
How do you become a system administrator in Colorado?
Colorado does not require a state-issued license to work as a system administrator, so the path runs through education and vendor credentials. Most employers expect a bachelor's degree in information technology or computer science, though an associate degree paired with strong certifications can open entry-level doors. CompTIA A+, Network+, and Security+ are widely recognized starting points, and Microsoft or AWS certifications carry particular weight with Colorado's defense contractors and healthcare systems.
How much do system administrators make in Colorado?
System administrators in Colorado earn a median of about $103,370 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $74,110 for the lowest 10% to over $155,050 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire system administrators in Colorado?
Employers hiring system administrators in Colorado right now include Lockheed Martin, Northrop Grumman, and Booz Allen Hamilton, based on current listings on Migrate Mate as of November 2026. Colorado's concentration of federal contractors, aerospace firms, and large regional health networks means steady, year-round demand rather than seasonal hiring spikes.
Which Colorado cities have the most system administrator jobs?
The cities with the most system administrator openings in Colorado are Colorado Springs, Aurora, and Littleton. Denver dominates because it anchors the state's technology, finance, and healthcare industries, while Colorado Springs draws significant volume from its dense cluster of military installations and defense contractors, and Boulder's university and research institutions generate consistent demand for infrastructure support.
Are there remote system administrator jobs in Colorado?
Yes, but they're less common than in purely analytical roles because system administrators are frequently needed on-site to manage physical hardware, data center equipment, and local network infrastructure. About 21% of system administrator openings tied to Colorado are remote or hybrid as of November 2026, with remote work most often attached to cloud-focused or monitoring-heavy positions rather than roles with hands-on server room responsibilities.
How can I get hired as a system administrator in Colorado with little or no experience?
The most realistic entry path is through a help desk or IT support technician role, which Colorado's large employers in healthcare, higher education, and state government hire for regularly and use as a pipeline into system administration. Institutions like UCHealth, the University of Colorado system, and the Colorado Department of Personnel and Administration post associate and entry-level IT positions that build the hands-on exposure hiring managers look for. Earning CompTIA A+ and Network+ before applying gives candidates a measurable edge even without professional experience.
Where can I find and apply to system administrator jobs in Colorado?
You can find and apply to system administrator jobs in Colorado on Migrate Mate, which lists current Colorado openings updated in real time. Search the listings to find roles that match your experience level and location preference, then apply directly to the ones that fit.
