Back End Developer Jobs in Colorado: Frequently Asked Questions
How do you become a back end developer in Colorado?
Back end developer is not a state-licensed occupation in Colorado, so there is no required board exam or state registration. Most employers hire candidates who hold a bachelor's degree in computer science or software engineering, or who have completed a rigorous coding bootcamp combined with a strong portfolio. Colorado's universities, including the University of Colorado system and Colorado State University, produce a steady pipeline of graduates that local employers actively recruit.
How much do back end developers make in Colorado?
Back end developers 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 back end developers in Colorado?
Companies currently hiring back end developers in Colorado include RTX, L3Harris, and LearnLux, per current listings on Migrate Mate as of October 2026. Colorado's mix of aerospace and defense contractors, financial services firms, and software companies means back end roles appear across a wide range of industries, not only pure tech startups.
Which Colorado cities have the most back end developer jobs?
Denver, Littleton, and Colorado Springs have the most back end developer openings in Colorado. Denver dominates the list because it hosts the state's largest concentration of tech companies, financial institutions, and corporate headquarters, while Boulder's startup and research ecosystem and Colorado Springs' defense and aerospace employers account for most of the activity outside the metro core.
Are there remote back end developer jobs in Colorado?
Yes, and more than most fields. About 100% of back end developer openings tied to Colorado are remote or hybrid as of October 2026, reflecting how well the work translates to distributed teams. Roles focused on API development, cloud infrastructure, and microservices tend to be the most consistently offered as fully remote positions.
How can I get hired as a back end developer in Colorado with little or no experience?
The most realistic entry path is an associate software engineer or junior developer role, which large Colorado employers like Lockheed Martin and DISH Network post specifically for candidates with limited professional experience. Building a portfolio of personal or open-source projects demonstrating API design and database work is the credential that carries the most weight. Many Colorado-based companies also run structured internship and new-grad programs that convert to full-time offers, so targeting those programs directly is a practical first step.
