Senior Facilities Mechanical Engineer (Dry Systems)

Our vision is to transform how the world uses information to enrich life for all . Micron Technology is a world leader in innovating memory and storage solutions that accelerate the transformation of information into intelligence, inspiring the world to learn, communicate and advance faster than ever. Systems Ownership Scope As the designated System Owner, the incumbent holds end-to-end technical accountability for the following mechanical utility systems across their full lifecycle — build, construction, commissioning, and operation: Compressed Dry Air (CDA): oil-free air compressors, heat-regenerative desiccant dryers, filtration trains, receivers, and distribution loops meeting ISO 8573 purity standards for particles, dew point, and oil. Process Vacuum (PVAC): vacuum pump packages, variable-speed skids, vacuum headers, tanks and point-of-use control. Process Exhaust: General exhaust (GEX), wet exhaust (WEX) fan systems, scrubber systems, ductwork, dampers, and monitoring. HVAC / Air Conditioning: make-up air units (MAU), dry cooling coil (DCC), computer room air conditioning (CRAC), air handling units (AHU), fan filter unit (FFU), fan coil unit (FCU) and comfort-cooling systems supporting office, cleanroom-support, and general areas. Associated instrumentation, control loops, and integration into the Building Management System (BMS). Shows readiness and capability to incorporate AI-powered tools into everyday engineering tasks such as predictive maintenance, energy management, and data-driven optimization of mechanical utility systems. This supports Micron's AI transformation and smart-manufacturing objectives. Construction Phase — Build, Delivery & Commissioning Develop and review the foundational plans, load calculations, and system sizing for CDA, PVAC, exhaust, and HVAC systems in accordance with Micron global standards and applicable codes. Define equipment specifications, redundancy approach, and turndown strategy for compressors, dryers, vacuum pumps, and fans. Review and challenge consultant build deliverables: P&IDs, single-line diagrams, equipment schedules, and layout for maintainability and future expansion. Review contractor submittals, method statements, and material approvals to confirm alignment with Micron global standards and applicable engineering standards. Support technical bid evaluation and equipment selection. Ensure the build incorporates energy efficiency, maintainability, and demand-based control from the beginning. Coordinate contractors and OEM vendors during installation to confirm compliance with drawings and specifications. Observe factory acceptance tests (FAT) and site acceptance tests (SAT) for compressors, dryers, vacuum packages, and air-handling equipment. Verify pipework fabrication, cleanliness, pressure testing, and passivation for CDA and vacuum lines to prevent contamination. Manage installation punch-lists, non-conformance reports, and interface coordination between mechanical, electrical, and controls trades. Confirm safety systems, isolation points, and LOTO provisions are accurately installed and detailed. Lead commissioning and system start-up; develop and complete commissioning protocols and qualification test plans. Verify CDA purity qualification to the required ISO 8573 classes for particles, dew point (pressure dew point), and oil including accurate sampling and line-flushing methodology. Validate vacuum system ultimate pressure, response, and capacity at point-of-use; confirm exhaust flow balancing and static-pressure set-points. Qualify HVAC performance: temperature, humidity, air-change rates, filtration, and pressurization to ISO 14644 cleanroom classifications. Support tool-install hook-up and utility readiness aligned to fab ramp achievements; hand over qualified systems with complete turnover packages and initial maintenance plans. Operational Phase — Operations, Maintenance & Budget Act as the responsible O&M lead for designated systems throughout their
