Responsibilities

Lead the design and engineering of cooling water systems supporting operational and project infrastructure.
Develop system architectures, P&IDs, flow diagrams, hydraulic calculations, equipment specifications, and design documentation.
Perform engineering analysis related to heat transfer, fluid flow, pump sizing, pressure drops, thermal stability, and water quality management.
Specify and oversee procurement of pumps, heat exchangers, filtration systems, expansion tanks, piping systems, valves, instrumentation, and water treatment systems.
Coordinate integration of water systems with process equipment, HVAC, mechanical systems, and facility utilities.
Ensure designs comply with applicable ASME, ANSI, building and mechanical codes, engineering standards, and safety requirements.
Oversee the operation of closed-loop LCW and DI water systems, monitoring critical parameters such as resistivity, dissolved oxygen (DO), and pH.
Manage chemical dosing, UV sterilizers, mixed-bed deionizers, and reverse osmosis (RO) systems to prevent biological growth, scaling, and galvanic corrosion.
Develop and execute preventative maintenance (PM) schedules.
Troubleshoot mechanical, electrical, and chemical issues, including pump failures, resin degradation, and leaks.
Plan, design, and commission system expansions or retrofits.
Evaluate pipe materials such as PVDF and electropolished stainless steel, along with valves and instrumentation, to maintain ultra-pure water standards.
Ensure water systems adhere to applicable environmental and industrial safety standards.
Serve as system owner for operational water systems.
Develop preventive and predictive maintenance programs for cooling water infrastructure.
Monitor system performance, reliability, and lifecycle condition.
Troubleshoot operational issues including flow instability, thermal excursions, equipment failures, water chemistry concerns, and leakage events.
Coordinate outages, repairs, commissioning activities, and maintenance schedules to minimize operational impact.
Support operational reliability and rapid response during facility incidents or system failures.
Manage water-system-related projects from conceptual design through installation and commissioning.
Coordinate with contractors, vendors, installation teams, and facilities personnel.
Develop project schedules, cost estimates, and technical scopes of work.
Review installation quality and ensure conformance with engineering specifications.
Support startup, testing, balancing, and commissioning activities.
Maintain accurate engineering documentation, including drawings, specifications, operating procedures, maintenance procedures, system inventories, and engineering calculations.
Support configuration management and change control processes.
Develop operational standards and best practices for facility water systems.
Ensure all activities are conducted in accordance with Integrated Safety Management (ISM), EH&S requirements, organizational policies, and applicable regulatory standards.
Participate in hazard analyses, readiness reviews, and safety assessments.
Support lockout/tagout planning and operational safety procedures.
