We are seeking an Environmental Engineer Specialist for our Water Quality Division's Groundwater Protection Inspection & Compliance Enforcement Unit. As an Underground Injection Control (UIC) Inspector, you will safeguard vital subsurface drinking water resources by evaluating and overseeing regional injection operations.

Key Responsibilities:
● Level 2 (EES 2) - Moderately Complex Oversight: Perform UIC well compliance evaluations, conduct physical field inspections, witness MITs, calculate fluid dynamics/pressures, and draft technical/enforcement reports.
● Level 3 (EES 3) - Advanced Technical Lead Oversight: Lead engineering oversight for Class I–VI wells, review complex UIC permits, witness advanced MITs, perform hydrogeologic modeling, and support legal enforcement actions.

This position is in the field 1-2 days per week/outdoors.

This position may offer the ability to work remotely, within Arizona, based upon the department's business needs and continual meeting of expected performance measures.

The State of Arizona strives for a work culture that affords employees flexibility, autonomy, and trust. Across our many agencies, boards, and commissions, many State employees participate in the State’s Remote Work Program and are able to work remotely in their homes, in offices, and in hoteling spaces. All work, including remote work, should be performed within Arizona unless an exception is properly authorized in advance.
