Project Assistant Jobs in Colorado: Frequently Asked Questions

How do you become a project assistant in Colorado?

Most project assistant roles in Colorado require a bachelor's degree in business, communications, or a related field, though some employers accept an associate degree combined with relevant work experience. Colorado does not require a state-issued license for this role. Earning a recognized credential such as the Certified Associate in Project Management strengthens your candidacy, particularly with Colorado's large defense contractors, health systems, and engineering firms along the Front Range.

Which companies hire project assistants in Colorado?

Employers hiring project assistants in Colorado right now include Quanta Services, Interstates Companies, and The Walsh, based on current listings on Migrate Mate as of October 2026. Colorado's concentration of defense contractors, regional health networks, and engineering firms means demand for project support staff stays consistent throughout the year.

Which Colorado cities have the most project assistant jobs?

Denver, Aurora, and Windsor have the most project assistant openings in Colorado. Denver drives the largest volume given its density of corporate headquarters, healthcare systems, and technology employers, while Colorado Springs benefits from a strong defense and aerospace sector and Boulder from its concentration of research institutions and technology companies.

Are there remote project assistant jobs in Colorado?

Yes, and they are more common than in many fields. About 24% of project assistant openings tied to Colorado are remote or hybrid as of October 2026, reflecting how much of the work involves scheduling, documentation, and digital coordination rather than on-site presence. Roles supporting software, consulting, and administrative functions tend to be the most remote-friendly.

How can I get hired as a project assistant in Colorado with little or no experience?

The most realistic entry path is through an administrative assistant or office coordinator role at a large Colorado employer, then moving laterally into project support once you have demonstrated organizational skills. UCHealth, Lockheed Martin, and the University of Colorado system all run associate or coordinator programs that consider candidates without direct project experience. Building proficiency in tools like Microsoft Project and earning the Certified Associate in Project Management credential gives you a concrete edge over other applicants.

Where can I find and apply to project assistant jobs in Colorado?
