Job description

Req. ID: JR109925 Senior Facilities Mechanical Engineer (Wet 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 engineer holds end-to-end technical accountability for the following mechanical utility systems across their full lifecycle — build, construction, commissioning, and operation:

• Chilled Water – Medium-Temperature (MTCHW): centrifugal / screw chillers, primary-secondary or variable-primary pumping, cooling towers, and distribution to HVAC and process loads.
• Chilled Water – Low-Temperature (LTCHW): low-temperature chiller plant serving process and dehumidification loads with tighter temperature control.
• Process Cooling Water (PCW): closed-loop tool-cooling system — vertical/inline pumps, plate heat exchangers, filtration, chemical dosing, and detailed temperature/flow regulation according to tool specifications.
• Ethylene Glycol (EG) / Low-Temperature Loop: sub-zero glycol refrigeration package(s), pumps, filtration, and distribution for process temperature control.
• Associated cooling towers, water-treatment / chemical-dosing systems, expansion tanks, instrumentation, and BMS integration.
• Shows readiness and capability to incorporate AI-powered tools into everyday engineering tasks. These include 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

• Review the basis for the build, cooling-load calculations, and hydraulic sizing for chilled water, PCW, and EG systems against Micron global standards and applicable codes.
• Define chiller plant configuration, redundancy philosophy, pumping strategy, and part-load efficiency targets (kW/RT, IPLV).
• Review and challenge build deliverables: P&IDs, hydraulic models, pump/chiller schedules, and pipe routing for maintainability, hydraulic balance, and future tie-in capacity.
• Review contractor submittals, method statements, and material approvals to ensure they meet Micron global standards and applicable engineering standards.
• Lead / support equipment tender evaluations, including performance-guarantee and energy-savings considerations.
• Specify water-treatment, filtration, corrosion-control, and chemical-dosing regimes to protect closed-loop water quality.
• Coordinate contractors and OEM vendors during installation to confirm compliance with drawings and specifications.
• Witness factory acceptance tests (FAT) for chillers, pumps, and heat exchangers; verify site acceptance testing (SAT).
• Supervise pipework fabrication, welding, flushing, chemical cleaning, passivation, and pressure testing of chilled-water, PCW, and glycol lines.
• Manage installation punch-lists, non-conformance reports, and coordination between mechanical, electrical, controls, and structural trades.
• Verify isolation valves, drain/vent points, and LOTO provisions for safe maintainability of pumps, chillers, and exchangers.
• Lead commissioning and system start-up; develop and complete commissioning protocols and qualification test plans.
• Balance hydraulic loops; verify built flow, differential pressure, and delta-T across chillers, PCW loops, and EG circuits.
• Assess temperature-control stability and capacity at point-of-use according to tool specifications; confirm chiller staging and plant sequence-of-operations.
• Support tool-install hook-up, new mechanical utilities loop tie-ins to existing systems (managing risk and continuity), and utility readiness aligned to fab ramp achievements.

Operational Phase — Operations, Maintenance & Budget

• Act as the responsible O&M owner for assigned systems during their operational service life, ensuring safe and conscientious 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 cooling-tower water treatment and Legionella-control programmes, chemical-dosing regimes, and closed-loop water-quality maintenance.
• Continuously monitor system performance via BMS and drive optimization of energy (kW / efficiency), 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).
• Own chiller-plant efficiency (kW/RT) as the primary optimization benchmark: optimized staging, condenser-water reset, variable-primary flow, delta-T management, and AI-based plant optimization.
• Take responsibility for, schedule, and estimate the annual 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 follows 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 mechanical or facilities engineering experience is required, focusing on central chilled-water plants, process cooling water, low-temperature glycol systems, and other mechanical utility 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.
• Having a Registered Energy Manager (REM) Type 1 or Type 2 certification under EECA 2024 is helpful for energy-related responsibility.
• Holding a Project Management Professional (PMP®) or a similar certification is helpful for capital-project delivery and budget management.
• 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
