This position may require prolonged periods of sitting, standing, walking, computer work, and occasional exposure to moderate levels of noise, dust, and fumes in production areas.
WHAT TO EXPECT
We're on a mission to unlock the potential of space to improve life on Earth, but that's not an easy task. It takes hard work, determination, relentless innovation, teamwork, grit, and an unwavering commitment to achieving what others often deem impossible. Our people out-think, out-work, and out-pace. We pride ourselves on having each other's backs, checking our egos at the door, and rolling up our sleeves on all tasks big and small. We thrive under pressure, work to tight deadlines, and our focus is always on how we can deliver, rather than dwelling on the challenges that stand in the way.

Senior Software Engineering Jobs in Colorado: Frequently Asked Questions
How do you become a senior software engineering in Colorado?
There is no state-issued license required to work as a senior software engineer in Colorado. The typical path involves earning a bachelor's degree in computer science, software engineering, or a closely related field, then building several years of hands-on experience in progressively complex roles. Colorado employers heavily weight a strong portfolio, open-source contributions, and demonstrated leadership on production systems when evaluating candidates for senior-level positions.
How much do senior software engineerings make in Colorado?
Senior software engineerings 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 senior software engineerings in Colorado?
Colorado senior software engineering roles are posted by L3Harris, Walmart, and Rocket Lab USA and others right now, based on current listings on Migrate Mate as of November 2026. Colorado's mix of defense contractors, technology scaleups, and financial services firms creates consistent senior-level demand across the Front Range year-round.
Which Colorado cities have the most senior software engineering jobs?
Denver, Colorado Springs, and Littleton have the most senior software engineering openings in Colorado right now. Denver drives volume through its dense concentration of fintech firms, cloud companies, and corporate technology divisions, while Boulder's startup and research ecosystem and Colorado Springs' defense and aerospace contractors generate steady demand outside the capital metro.
Are there remote senior software engineering jobs in Colorado?
Yes, and more than most fields. About 50% of senior software engineering openings tied to Colorado are remote or hybrid as of November 2026, reflecting how well the work translates to distributed teams. Backend platform roles and cloud infrastructure positions tend to be the most consistently remote, while embedded systems and defense-clearance roles almost always require on-site presence.
How can I get hired as a senior software engineering in Colorado with little or no experience?
The most realistic entry path is through associate or junior software engineer roles at Colorado employers who run structured early-career programs, then building toward senior over several years. Lockheed Martin and Raytheon both run new-graduate rotational engineering programs at their Colorado sites. A strong GitHub portfolio, contributions to open-source projects, and passing cloud certification exams from AWS or Google give candidates without deep professional experience a concrete edge in Colorado interviews.
Where can I find and apply to senior software engineering jobs in Colorado?
You can find and apply to senior software engineering jobs in Colorado on Migrate Mate, which lists current Colorado openings across the Front Range and beyond. Find roles that fit your experience and specialization and apply directly to the employer from each listing.
