  • Minimum of 8 years of relevant professional engineering experience, including substantial experience designing, operating, or maintaining industrial process or facility water systems; an equivalent combination of education and experience may be considered.
  • Demonstrated knowledge of low-conductivity water (LCW) and deionized (DI) water systems, including water purity, corrosion prevention, chemical treatment, and troubleshooting.
  • Experience with closed-loop cooling systems, industrial piping, process utilities, and mechanical infrastructure.
  • Strong understanding of hydraulic engineering, fluid flow, heat transfer, pressure management, and thermal system design.
  • Experience developing, interpreting, and maintaining engineering drawings and P&IDs.
  • Familiarity with pumps, heat exchangers, cooling towers, filtration systems, water treatment equipment, instrumentation, and controls.
  • Demonstrated troubleshooting, root-cause analysis, and equipment reliability experience.
  • Ability to coordinate multiple engineering projects and operational priorities.
  • Strong written and verbal communication skills, with the ability to collaborate across multidisciplinary technical teams.

Nice To Haves

  • Professional Engineer (PE) license.
  • Experience supporting scientific research facilities, particle accelerators, semiconductor manufacturing, or other high-availability technical environments.
  • Experience with EPICS or industrial control systems integration.
  • Familiarity with vibration-sensitive equipment and thermally stable cooling systems.
  • Experience commissioning and starting up large-scale mechanical utility systems.
  • Knowledge of reliability-centered maintenance and predictive maintenance methodologies.
  • Previous experience supporting Department of Energy (DOE) national laboratories or comparable research facilities.

Responsibilities

  • Lead the design, engineering, and optimization of cooling water systems supporting ALS-U and existing ALS infrastructure.
  • Develop piping and instrumentation diagrams (P&IDs), flow diagrams, hydraulic calculations, equipment specifications, and technical documentation.
  • Perform engineering analyses involving heat transfer, fluid dynamics, pump sizing, pressure drops, thermal stability, and water quality.
  • Specify and support procurement of pumps, heat exchangers, filtration systems, expansion tanks, piping, valves, instrumentation, and water treatment equipment.
  • Coordinate integration of cooling water infrastructure with accelerator, beamline, cryogenic, HVAC, and facility utility systems.
  • Ensure engineering designs comply with applicable ASME, ANSI, California mechanical and building codes, and laboratory safety standards.
  • Oversee the operation and maintenance of closed-loop low-conductivity water (LCW) and deionized (DI) water systems.
  • Monitor critical water quality parameters, including resistivity, dissolved oxygen, pH, and system performance.
  • Manage and optimize chemical treatment processes, UV sterilization, mixed-bed deionization, and reverse osmosis (RO) systems.
  • Identify and mitigate biological growth, scaling, corrosion, contamination, and water chemistry concerns.
  • Troubleshoot equipment failures, leaks, pump malfunctions, resin degradation, flow instability, and thermal excursions.
  • Evaluate piping materials, valves, and instrumentation to maintain system integrity and water purity.
  • Develop and implement preventive and predictive maintenance programs for critical cooling water infrastructure.
  • Evaluate equipment reliability, lifecycle conditions, and opportunities for operational improvement.
  • Coordinate maintenance activities, repairs, shutdowns, and system upgrades to minimize facility downtime.
  • Support installation, startup, testing, balancing, and commissioning of new and modified water systems.
  • Provide technical support during operational incidents and system failures.
  • Manage engineering projects from conceptual design through installation and commissioning.
  • Collaborate with engineering teams, contractors, vendors, facilities personnel, and scientific staff.
  • Develop project schedules, cost estimates, technical scopes of work, and equipment specifications.
  • Review installation quality and verify compliance with approved engineering requirements.
  • Maintain engineering drawings, operating procedures, maintenance records, system inventories, and configuration documentation.
  • Support engineering change control and continuous improvement initiatives.
  • Ensure work complies with Integrated Safety Management (ISM), Environmental Health & Safety (EH&S) requirements, laboratory policies, and applicable regulations.
  • Participate in hazard analyses, readiness reviews, and safety assessments.
  • Support lockout/tagout procedures, safe equipment isolation, and operational safety planning.
  • Promote safe engineering and maintenance practices throughout facility operations.
