Company Description
WD is building the infrastructure behind the AI-driven data economy.
As AI scales, so does data. Every interaction, every model, every system generates data that must be stored, managed, and made accessible over time. That’s where we come in.
We combine deep engineering expertise with global-scale manufacturing to deliver the storage systems that make AI possible, powering hyperscale data centers, cloud platforms, and enterprise infrastructure worldwide.
This isn’t theoretical work. It’s real systems, at real scale, people solving some of the hardest challenges in technology today.
We’re looking for people who want to build, solve, and operate at that level.
Join us and let’s shape the future of data.
Job Description
What you'll do
HVAC Project Design, Engineering & ExecutionCapital Planning & Budgeting: Support HVAC capital budget planning, including life-cycle analysis for critical equipment (Chillers, Cooling Towers, AHUs), and prepare technical justifications for upgrades or replacements.
Technical Design & Feasibility: Conduct feasibility studies and lead design reviews—including cooling load calculations, psychrometric, and air distribution—to support production expansion and cleanroom requirements.
End-to-End Project Management: Lead HVAC projects from concept to commissioning; prepare detailed Scopes of Work, conduct vendor technical evaluations, and ensure strict adherence to ISO 14644 standards, timelines, and quality requirements.
Cleanroom Control, Compliance & RedundancyEnvironmental Parameter Management: Monitor and maintain stable controlled environments (Temperature, %RH, Particle count, and Delta P) to ensure production utilities remain qualified and compliant with industry standards.
Downtime Mitigation: Manage and maintain N+1 redundancy configurations for critical utilities to eliminate the risk of production downtime due to environmental excursions.
Energy Optimization & SustainabilityDecarbonization Initiatives: Drive sustainability goals by implementing energy-saving programs (e.g., Chiller Plant Optimization) and managing the transition to Low-GWP (Global Warming Potential) refrigerants.
Advanced Troubleshooting & CAPARoot Cause Analysis: Lead deep-dive technical troubleshooting for complex HVAC failures, generating comprehensive 8D reports and implementing effective Corrective and Preventive Actions (CAPA).
Project Handover, O&M Support & SafetyOperational Handover: Coordinate smooth project transitions to the Operations & Maintenance (O&M) team by updating As-built drawings via AutoCAD, conducting technical training, and providing spare parts lists and maintenance manuals.
Contractor Safety Supervision: Supervise and monitor HVAC contractors during high-risk tasks, ensuring full compliance with safety protocols to achieve zero-accident execution without impacting ongoing production.
Requirements
Educational Background: Bachelor’s degree or higher in Mechanical Engineering Or related.
Industry Expertise: Proven experience in the Electronics industry or High-Tech manufacturing; specific knowledge of ISO 14644 and environmental control requirements.
