Job description

Summary

Utility Engineer will conduct full-process technical management of plant-wide process utility systems covering chillers, boilers, pure water, compressed air, vacuum and cooling water supply systems. Support new fab construction, stable equipment operation, energy consumption control and production capacity expansion.

Job Duties

• New project technical coordination: Take charge of scheme review, construction coordination, on-site construction supervision, system commissioning & acceptance, asset handover and closed-loop rectification of pending issues for all utility systems of new cleanrooms.
• Technical management of utility systems: Manage all plant-wide utility infrastructure, including chillers, boilers, DI water systems, Clean Dry Air (CDA), vacuum systems, Process Cooling Water (PCW), circulating water and factory water supply & drainage systems.
• Operation and energy consumption control: Compile standard operating procedures, graded preventive maintenance plans and energy optimization schemes for all utility equipment. Continuously monitor the load, medium pressure, flow rate and energy consumption indicators of core equipment such as chillers, boilers, water pumps and air compressors to ensure uninterrupted and stable supply of process utilities.
• Fault handling & technical upgrading: Lead root cause analysis on shutdown failures of chillers, boilers, water and air utility systems, hidden danger investigation and rectification. Take charge of capital renovation projects including utility system capacity expansion, pipeline reconstruction, chiller and boiler replacement & upgrading.
• Technical guidance for operation teams: Provide comprehensive technical support to workshop utility maintenance teams, standardize inspection and maintenance workflows for chillers, boilers, pure water and air compression equipment.
