Development Engineer Jobs in Colorado: Frequently Asked Questions
How do you become a development engineer in Colorado?
Most development engineer roles in Colorado require a bachelor's degree in engineering from an ABET-accredited program, with mechanical, electrical, aerospace, and systems engineering being the most common disciplines. Colorado does not require a state license for most private-sector development engineer roles, though engineers who sign off on public projects may pursue Professional Engineer registration through the Colorado State Board of Licensure for Architects, Professional Engineers, and Professional Land Surveyors.
How much do development engineers make in Colorado?
Development engineers in Colorado earn a median of about $125,800 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $80,130 for the lowest 10% to over $188,640 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire development engineers in Colorado?
Companies currently hiring development engineers in Colorado include Amazon Web Services, Amazon, and SGM, per current listings on Migrate Mate as of November 2026. Colorado's concentration of aerospace, defense, and advanced manufacturing employers means development engineers here are frequently hired into programs supporting satellites, defense systems, and energy technology.
Which Colorado cities have the most development engineer jobs?
Denver, Colorado Springs, and Englewood account for the most development engineer openings in Colorado. Denver anchors the market through its aerospace and defense prime contractors, Boulder draws roles tied to research-oriented tech and energy companies, and Colorado Springs supports a large concentration of defense and space systems work driven by nearby military installations and contractors.
Are there remote development engineer jobs in Colorado?
Yes, but they're less common than in purely desk-based fields, because development engineering frequently involves hands-on lab work, hardware testing, and on-site collaboration. About 38% of development engineer openings tied to Colorado are remote or hybrid as of November 2026, with the remote share concentrated in software-adjacent development roles, systems architecture, and technical program coordination rather than hardware or test engineering.
How can I get hired as a development engineer in Colorado with little or no experience?
The most realistic entry path is applying to new-graduate rotational or associate engineer programs at Colorado's large aerospace and defense employers, including Lockheed Martin Space in Littleton, Raytheon in Aurora, and Ball Aerospace in Westminster, all of which run structured programs for candidates with engineering degrees and no professional experience. Internship experience, a completed senior capstone project, or an EIT designation from the Colorado State Board strengthens a new-graduate application. Lateral entry from adjacent roles such as test technician, manufacturing engineer, or quality engineer is another common path into development roles.
Where can I find and apply to development engineer jobs in Colorado?
You can find and apply to development engineer jobs in Colorado on Migrate Mate, which lists current Colorado openings updated regularly. Search the roles available, find the ones that match your background and target employers, and apply directly through each listing.
