What Happens After You Apply.

Are you passionate about protecting public health, safeguarding the environment, and ensuring accountability? The Vehicle Services Program (VSP) is seeking a dedicated, analytical, and detail-oriented Air Environment Systems Technician (AEST) to serve as a key enforcement expert in Colorado’s Emissions Program. In this vital role, you will be on the front lines of environmental compliance across the Front Range—monitoring, analyzing, and auditing emissions testing facilities to keep Colorado’s air clean and safe for everyone.

VSP ensures statewide compliance with Colorado Revised Statutes governing vehicle titling, registration, and emissions. Our Emissions Program oversees automobile inspections, station licensing, inspector certifications, and facility audits across ten Front Range counties. Managing over 80 locations, 450 inspectors, and diverse testing programs (Enhanced, Rapid Screen, and Diesel Opacity), our team maintains high standards of operational integrity and consumer protection.

• Statutory Compliance & Waiver Administration:
  Evaluate complex emissions data, vehicle records, and statutory requirements to independently grant or deny waivers for non-complying vehicles.
• Fraud Detection & Investigative Analysis:
  Perform deep-data analysis and physical inspections to detect, expose, and document fraudulent repair practices and illegal emissions control tampering.
• Equipment Calibration & Technical Audits:
  Ensure high-precision operational standards by validating and confirming the accurate calibration of constant volume samplers, dynamo meters, flame ionization units, and opacity meters.
• Station Oversight:
  Conduct rigorous, bi-monthly audits of both Contracted and Fleet diesel inspection stations to evaluate statutory compliance and equipment functionality.
• Quality Assurance & Regulatory Enforcement:
  Assess inspector competency and performance, holding authority to require additional mandatory training or issue formal penalties when non-compliance is identified.

• Meaningful Work:
  Directly contribute to improving air quality and public health across Colorado.
• State Benefits:
  Comprehensive healthcare options, generous retirement plans, paid time off, and stable career growth opportunities within state government.
• Dynamic Fieldwork:
  Balance analytical desk work with hands-on, high-impact field evaluations.
