Senior Engineer Facilities and Utilities

**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.
