We are seeking a skilled Ultrapure Water (UPW) & Wastewater Engineering Technician to support the reliable operation, maintenance, and optimization of critical process systems within a state-of-the-art semiconductor facility. This role ensures continuous availability of ultrapure and deionized water while maintaining environmental compliance across wastewater treatment systems.
Responsibilities:

• Operate, monitor, and maintain all Ultrapure Water (UPW), Deionized Water (DI), and Wastewater systems to ensure stable performance, compliance, and system reliability.
• Conduct daily rounds and readings, verifying process parameters, alarm conditions, and equipment health through field inspections and control systems (SCADA/BMS/Cimplicity).
• Perform preventive and corrective maintenance on mechanical, electrical, and instrumentation equipment in accordance with approved job plans and safety procedures.
• Execute calibration and verification of field instruments, including temperature, pressure, flow, conductivity, pH, level, and TOC sensors, ensuring traceability and documentation accuracy.
• Monitor process quality data and sample results, escalating deviations from specification to engineering and implementing corrective actions as directed.
• Collect and prepare process, environmental, and wastewater samples following chain-of-custody and analytical requirements, coordinating with laboratories and EHS teams as needed.
• Support troubleshooting and resolution of equipment alarms, process upsets, and system performance issues through root cause investigation and collaboration with engineering.
• Maintain and update all PM/CM activities, calibration results, and operational data within the CMMS (e.g., Maximo), ensuring traceable and compliant recordkeeping.
• Ensure strict adherence to all site safety standards including LOTO, confined space, arc flash, and chemical handling procedures.
• Maintain a clean, organized, and safe work environment across all process areas, tools, and maintenance equipment.
• As Shift Lead (when assigned), serve as the primary point of contact for shift operations-coordinating daily work execution, prioritizing PM/CM activities, assigning tasks to technicians, and ensuring completion of rounds, readings, and sampling requirements.
• Oversee system operation during assigned shifts, making on-the-spot operational decisions necessary to maintain process control, safety, and uptime, while escalating significant issues to engineering.
• Provide accurate shift passdowns, documenting all maintenance, alarms, and process events to ensure continuity across 24x7 operations.
• Act as Equipment Owner for assigned UPW/Waste assets, maintaining full accountability for system reliability, PM effectiveness, and performance tracking.
• Lead ownership responsibilities by initiating corrective work orders, coordinating repairs, verifying functionality post-maintenance, and updating equipment histories and documentation.
• Support engineering with performance data, system trends, and field insights to guide technical decisions, reliability reviews, and system optimization.
• Participate in system startups, commissioning activities, and requalification testing following major repairs or engineering modifications.
• Provide input on engineering change requests and setpoint adjustments, validating system impact and ensuring proper control response in the field.
• Maintain awareness of critical control loops and process interlocks, ensuring alarms and safeguards are operational and properly configured.
• Support environmental monitoring…
