Geologist Jobs in Colorado: Frequently Asked Questions
How do you become a geologist in Colorado?
To practice as a professional geologist in Colorado, you must obtain a Professional Geologist (P.G.) license through the Colorado Department of Regulatory Agencies, Division of Professions and Occupations. Licensure requires a qualifying degree in geology or a related earth science, documented work experience under a licensed professional, and passing the Association of State Board of Geology national exam. Many Colorado employers require or strongly prefer licensed candidates, particularly for environmental consulting, mining, and government roles.
How much do geologists make in Colorado?
Geologists in Colorado earn a median of about $114,410 a year, based on May 2025 Bureau of Labor Statistics wage data, ranging from around $70,410 for the lowest 10% to over $210,090 for the top 10%. Pay rises with experience, specialty, and employer.
Which companies hire geologists in Colorado?
Employers hiring geologists in Colorado right now include Onterris, Weaver Consultants, and AECOM, based on current listings on Migrate Mate as of August 2026. Colorado's combination of active oil and gas operations, metal mining, federal land management, and environmental consulting creates consistent demand across a broad mix of private companies and government agencies.
Which Colorado cities have the most geologist jobs?
Denver, Loveland, and Nucla have the most geologist openings in Colorado. Denver dominates due to the concentration of energy company headquarters, environmental consulting firms, and federal agencies along the Front Range, while Fort Collins draws hiring from Colorado State University research programs and regional consulting, and Grand Junction serves as the hub for Western Slope oil, gas, and uranium work.
Are there remote geologist jobs in Colorado?
Yes, but they're rare. Geology is a predominantly field-based and lab-driven profession, so most roles require on-site presence. About 50% of geologist openings tied to Colorado are remote or hybrid as of August 2026, reflecting the limited share of purely desk-based work. The roles most likely to offer remote flexibility are data interpretation, technical report writing, and GIS analysis positions within larger consulting or energy firms.
How can I get hired as a geologist in Colorado with little or no experience?
The most realistic entry path is a field technician or geology assistant role at an environmental consulting firm, which Colorado has in abundance across the Front Range. Firms such as Tetra Tech, Terracon, and Burns and McDonnell routinely bring on new graduates for field sampling and site assessment work. Completing a senior thesis project with field components, earning your Engineer-in-Training or Geologist-in-Training designation from the state, and gaining summer field experience through the U.S. Geological Survey or Colorado Geological Survey strengthens any entry-level application considerably.
Where can I find and apply to geologist jobs in Colorado?
You can find and apply to geologist jobs in Colorado on Migrate Mate, which lists current Colorado openings across industries including energy, mining, environmental consulting, and government. Search the roles that fit your specialty and experience level and apply directly to the ones that match.
