Software Systems Engineer Jobs in Colorado: Frequently Asked Questions
How do you become a software systems engineer in Colorado?
Most hiring managers in Colorado require at least a bachelor's degree in systems engineering, computer engineering, electrical engineering, or a closely related field. No state-issued license is required to work as a software systems engineer in Colorado. Candidates targeting defense and aerospace roles should pursue or be eligible for a DoD security clearance, which is effectively a prerequisite with major Colorado employers. Professional certifications such as INCOSE's Certified Systems Engineering Professional strengthen applications significantly.
How much do software systems engineers make in Colorado?
Software systems engineers in Colorado earn a median of about $138,390 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $96,480 for the lowest 10% to over $213,010 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire software systems engineers in Colorado?
Companies currently hiring software systems engineers in Colorado include Lockheed Martin, Vantor, and Blue Origin, per current listings on Migrate Mate as of September 2026. Colorado's deep concentration of aerospace, defense, and space technology firms means many of these employers run multi-year programs that generate consistent, long-term systems engineering demand.
Which Colorado cities have the most software systems engineer jobs?
Littleton, Boulder, and Denver lead Colorado for software systems engineer openings. Denver drives volume through its broad base of technology and government contracting firms, Colorado Springs is anchored by major defense installations and contractors like the Space Force and Raytheon, and Boulder's aerospace and research corridor, including Ball Aerospace and several NIST-affiliated organizations, accounts for a strong share of specialized systems roles.
Are there remote software systems engineer jobs in Colorado?
Yes, and more than in many engineering disciplines, though a significant share of Colorado roles require on-site work due to security clearance restrictions and hardware integration responsibilities. About 86% of software systems engineer openings tied to Colorado are remote or hybrid as of September 2026, reflecting a genuine split between cleared defense programs and commercial software-oriented systems roles. Model-based design, requirements management, and architecture work are the sub-areas most likely to permit remote arrangements.
How can I get hired as a software systems engineer in Colorado with little or no experience?
The most realistic entry path is through a systems engineering associate or junior engineer role at one of Colorado's large defense and aerospace primes, which regularly hire new graduates into structured programs. Lockheed Martin Space and Raytheon Intelligence and Space both operate early-career rotational programs based in Colorado. A degree in electrical, computer, or systems engineering is the strongest credential, and candidates who have completed capstone or senior design projects involving requirements definition or system-level testing stand out. Entry from adjacent roles like quality assurance engineer, integration and test engineer, or even a technical program coordinator position is also a well-traveled path into systems engineering at Colorado employers.
Where can I find and apply to software systems engineer jobs in Colorado?
You can find and apply to software systems engineer jobs in Colorado on Migrate Mate, which lists current Colorado openings updated continuously. Search the listings for roles that match your experience level, specialization, and preferred location, then apply directly to the ones that fit.
