Provide engineering support for recirculation units, make-up air systems, exhaust systems, acid scrubbers, RCTO solvent-abatement systems, AHUs, and VAV systems.

Respond to cleanroom HVAC OCAP conditions involving temperature, humidity, particle levels, and exhaust pressure.

Monitor performance through inspections, trend analysis, capacity planning, and technical reporting.

Apply FMEA, root-cause analysis, and reliability-engineering principles to improve system performance.

Identify and implement upgrades that improve reliability, energy efficiency, safety, and production capacity.

Support capital projects, expense projects, system modifications, and equipment hook-ups.

Maintain accurate operating, maintenance, and commissioning procedures.

Bachelor’s degree in Mechanical Engineering or a related discipline.

Five or more years of HVAC engineering experience covering design and operations.

Strong knowledge of HVAC systems, exhaust systems, controls, chilled-water systems, cooling towers, and cleanroom standards.
