About this role
Job Title:
Senior Engineer, Facilities and Utilities
Job Description:
The Role:
• This role is accountable for the safe, reliable, and efficient operation of HVAC (Heating, Ventilation, and Air Conditioning) systems in a semiconductor manufacturing environment. The position plays a key role in ensuring environmental control compliance, operational continuity, and advancing sustainability goals through system optimization and disciplined execution.
In this role you will:
• Own and drive preventive maintenance programs for HVAC systems to ensure system reliability, environmental compliance (temperature, humidity, cleanliness), and operational stability.
• Lead troubleshooting and root cause analysis of system upsets, applying structured methodologies (FMEA, HAZOP, 8D) to implement sustainable corrective and preventive actions.
• Partner cross-functionally with Process, Equipment, EHS, and external vendors to resolve issues, optimize HVAC performance, and support production operations.
• Identify and execute continuous improvement initiatives for HVAC systems, including energy efficiency, airflow optimization, and environmental stability enhancement.
• Lead capital and improvement projects, with full accountability for scope, schedule, cost, contractor management, and quality delivery.
• Drive ESG and sustainability programs, including energy reduction, carbon footprint optimization, and resource efficiency improvements.
Traits we believe make a strong candidate:
• 5+ years of experience in HVAC system operation, maintenance, and optimization, preferably in semiconductor or advanced manufacturing industries (cleanroom experience highly preferred).
• Solid understanding of HVAC systems, including air handling units (AHU), chillers, cooling towers, duct systems, exhaust systems, and cleanroom environmental control.
• Strong knowledge of thermodynamics, heat transfer, air filtration (HEPA/ULPA), humidity control, and contamination control.
• Ability to read and interpret P&ID, HVAC schematics, and airflow diagrams.
• Demonstrated analytical capability with hands-on experience in data analysis, SPC, trending, and root cause problem-solving.
• Familiarity with HVAC-related controls and BMS (Building Management System).
• Strong ownership mindset with the ability to independently drive issue resolution in a fast-paced, 24/7 operations environment.
• Effective communication and stakeholder management skills across multiple functions.
• Detail-oriented, proactive, and resilient under high operational demands.
Your success will be measured by:
• High reliability and uptime of HVAC systems, ensuring uninterrupted cleanroom and facility operation.
• Consistent achievement of cleanroom environmental specifications (temperature, humidity, particle count, pressure cascade).
• Reduction of recurring system issues through robust preventive maintenance and effective root cause resolution.
• Successful execution of projects within scope, timeline, cost, and quality expectations.
• Measurable improvements in system energy efficiency, airflow balance, and operational performance.
• Tangible contributions to sustainability and ESG targets, including energy savings and cost optimization.
