Staff Engineer, Facilities HVAC Engineering

Job Description

• Support HVAC capital budget planning, including life-cycle analysis for critical equipment (Chillers, Cooling Towers, AHUs), and prepare technical justifications for upgrades or replacements.
• Conduct feasibility studies and lead design reviews—including cooling load calculations, psychrometric, and air distribution—to support production expansion and cleanroom requirements.
• 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.
• Monitor and maintain stable controlled environments (Temperature, %RH, Particle count, and Delta P) to ensure production utilities remain qualified and compliant with industry standards.
• Manage and maintain N+1 redundancy configurations for critical utilities to eliminate the risk of production downtime due to environmental excursions.
• Drive sustainability goals by implementing energy-saving programs (e.g., Chiller Plant Optimization) and managing the transition to Low-GWP (Global Warming Potential) refrigerants.
• Lead deep-dive technical troubleshooting for complex HVAC failures, generating comprehensive 8D reports and implementing effective Corrective and Preventive Actions (CAPA).
• 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.
• Supervise and monitor HVAC contractors during high-risk tasks, ensuring full compliance with safety protocols to achieve zero-accident execution without impacting ongoing production.

Qualifications

• Educational Background: Bachelor’s degree or higher in Mechanical Engineering Or related.
• Professional Experience: At least 5 years in Facilities management or Engineering, with a strong focus on industrial HVAC system operations and projects.
• Industry Expertise: Proven experience in the Electronics industry or High-Tech manufacturing; specific knowledge of ISO 14644 and environmental control requirements.

Preferred

• License for Professional Practice from Council of Engineers Thailand
