The Senior Indoor Air Quality (IAQ) Engineer is the subject matter expert responsible for leading the design, strategy, and execution of IAQ compliance programs across water treatment facilities, administrative buildings, and critical utility environments. This role oversees ventilation design assessments, air quality risk mitigation, and ensures alignment with ASHRAE, OSHA, and EPA standards. The position plays a key leadership role in multidisciplinary projects involving HVAC system optimization, air purification technologies, and occupant health initiatives.
Develop and lead enterprise-wide IAQ programs for treatment plants and support facilities.
Establish IAQ performance baselines and compliance strategies for short- and long-term operational goals.
Conduct or oversee complex IAQ assessments including continuous monitoring, tracer gas testing, and airflow validation.
Provide advanced diagnostics for ventilation inefficiencies, contamination risks, and filtration limitations.
Review and approve HVAC designs to ensure full compliance with ASHRAE 62.1, 55, 170, and relevant building codes.
Recommend advanced air cleaning technologies (e.g., UVGI, ionization, activated carbon) where applicable.
Lead IAQ-related capital improvement projects, including retrofits of ventilation systems and high-efficiency filter upgrades.
Interface with contractors, engineering consultants, and controls specialists during project design, commissioning, and verification.
Serve as the primary liaison for environmental health audits and IAQ regulatory reporting.
Guide risk assessments for indoor air contamination, mold, Legionella, and VOC exposure.
Mentor junior IAQ engineers and support staff in diagnostics, standards, and field practices.
Deliver training sessions on IAQ best practices, HVAC operation impacts, and health-based ventilation strategies.
