Senior Facilities Mechanical Engineer (Dry Systems)

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 operational service life, ensuring safe, reliable 24/7 availability.
• Develop, own, and continuously refine the preventive (PM), predictive (PdM), and condition-based maintenance strategy using RCM / FMEA methodology.
• Plan and schedule all maintenance activities via the SAP PM; manage work orders, PM compliance, backlog, and shutdown / turnaround planning.
• Manage OEM service contracts, specialist vendors, and in-house technicians; define spare-parts strategy and critical-spares holding to protect uptime.
• Own reliability performance (MTBF, MTTR, availability); lead breakdown response, root-cause analysis, and corrective/preventive actions to eliminate repeat failures.
• Manage statutory inspections for dry-system pressure equipment (e.g., air receivers) including DOSH Certificate of Fitness (CF) renewals.
• Continuously supervise system performance via BMS and drive optimization of energy, capacity, and stability against build intent.
• Identify, justify, and deliver optimization and reliability-improvement projects with quantified return on investment, energy savings, and carbon-reduction benefits.
• Manage system upgrades, capacity expansions, tie-ins, and end-of-life equipment replacement with minimal production risk and full change management (MOC).
• Optimize compressed-air demand: leak-detection and repair programmes, pressure-band optimization, sequencing, VSD tuning, and heat-of-compression recovery.
• Take ownership for, plan, and predict the yearly maintenance operating budget (OPEX) for assigned systems including spares, consumables, service contracts, and labor.
• Prepare the yearly budget submission with clear, data-driven justification; track actual spending against budget and manage variances monthly.
• Build and justify the maintenance/repair capital (CAPEX) case for equipment replacement, overhaul, and reliability upgrades using lifecycle-cost analysis.
• Drive cost optimization without compromising safety or reliability, negotiate service contracts, optimize spares inventory, and make data-driven repair-vs-replace decisions.
• Report budget performance, savings, and cost indicators to management; ensure spending aligns with procurement and financial-governance requirements.
• Support ISO 50001 Energy Management System requirements, energy audits, and reporting obligations under the Energy Efficiency & Conservation Act 2024 (EECA 2024).
• Provide technical mentorship to engineers, technicians, and operators on assigned systems.
• Represent Facilities in internal, corporate, customer, and third-party audits (e.g., ISO surveillance, customer quality audits) as system subject-matter expert.
• Collaborate with process/tool-install, construction, and global facilities teams to align utility delivery with fab ramp schedules.

Job Requirements

• Bachelor’s Degree or equivalent experience in Mechanical Engineering, Mechatronics, or a closely related engineering field from a recognized university (accredited by MQA or Engineering Accreditation Council).
• At least 5 years of applicable mechanical / facilities engineering experience, focusing heavily on compressed air, vacuum, exhaust, cleanroom, and HVAC systems.
• Direct experience in a semiconductor, wafer-fab, data-centre, pharmaceutical, or other high-purity / critical cleanroom environment and able to support shift, weekend, night or emergency work when required.
• Solid grounding in thermodynamics, fluid mechanics, heat transfer, and rotating-equipment fundamentals.
• Holding a Registered Energy Manager (REM) Type 1 or Type 2 certification under EECA 2024 is helpful for energy-related responsibility.
• Having a Project Management Professional (PMP®) or a comparable certification is helpful for delivering capital projects and managing budgets.
• Experienced in capital project delivery from concept build through commissioning and hand-over to operations, followed by long-term O&M ownership.
• Hands-on experience owning an annual maintenance budget (OPEX) planning, forecasting, and cost control against target.
• Solid understanding of BMS platforms, SAP PM, AI tools and AI-enabled ways of working to improve efficiency, productivity, and decision-making.
