Principal Air Quality Compliance Engineer

Metro Water Recovery in Denver, CO - a nationally recognized leader among clean water utilities, provides wastewater conveyance and treatment services for more than 2 million people in the Denver Metro area.

At Metro, we help you be your best so we can do our best. You will join a team that offers stability, flexibility, and the opportunity to make a difference. We take pride in being part of an industry-leading team who serves the community by protecting the region’s health and environment.

We are seeking an experienced Principal Air Quality Compliance Engineer to lead and perform complex technical and regulatory work supporting our facilities. This is a hands‑on role. You will perform air quality engineering and regulatory work from start to finish—developing defensible emissions calculations and inventories, preparing permit applications and compliance documentation, interpreting regulatory requirements, and evaluating equipment and process changes to ensure compliance with federal and Colorado air quality regulations.

You will support Metro’s operations and capital project teams to integrate environmental requirements into planning, design, construction, and implementation.

You will also provide support for regulatory stakeholders and rule‑making processes, analyzing revised and proposed regulations, assessing operational, permitting, and compliance impacts, and preparing defensible, sound input.

Air quality compliance is the primary focus of this role. But as part of a small environmental compliance team of engineers and scientists, you will also support Metro’s other environmental program areas.

• Bring deep working knowledge and experience with federal and Colorado Clean Air Act requirements
• Are comfortable independently performing complex emissions evaluations and calculations
• Prepare clear, technically sound permit applications and regulatory submittals
• Can translate regulatory requirements into practical solutions for operations and capital projects
• Engage confidently in technical and regulatory discussions with regulators and stakeholders
• Work effectively in a small interdisciplinary team where principal engineers actively perform the work
• Are comfortable working in a fast‑paced, dynamic environment
• Enjoy mentoring and sharing your knowledge and experience
• Have a Colorado Professional Engineering license or the ability to obtain one via reciprocity

We value excellence, integrity, inclusion, and collaboration, and we’re looking for someone who shares these values.
