Process Technician (Dialysate Production — RO & Mixing Systems)

You will maintain and repair the purified water (RO / EDI / UF) system, mixing tank, and associated equipment used to produce dialysis fluid. The role covers mechanical, electrical, instrumentation, and basic automation tasks on Siemens SIMATIC PLC-based systems (TIA Portal / WinCC), plus GMP-style documentation and vendor coordination.

Overview

Responsibilities

• Operations & maintenance : Execute daily checks, PMs, and corrective maintenance for RO skids, pre-treatment (cartridge / softener / carbon), EDI / UF, pumps, mixing tanks, agitators, valves, heat exchangers, and CIP systems.
• Replace / clean RO membranes and filters; perform CIP / SIP and chemical sanitization (e.g., NaOH, HCl, NaOCl) safely.
• Monitor and optimize process parameters : pressure, flow, temperature, conductivity / resistivity, pH, ORP, TOC (where applicable).
• Automation & controls : Monitor Siemens SIMATIC PLC / SCADA (TIA Portal / WinCC); acknowledge and troubleshoot alarms; adjust setpoints within approved limits.
• Support instrumentation calibration (pressure / flow / level / temperature / conductivity) using HART or handheld calibrators.
• Work with integrators / OEMs on logic or HMI issues; assist in I / O checks and FAT / SAT when upgrades occur.
• Troubleshooting : Systematically diagnose electrical (VFDs, contactors, sensors), hydraulic (cavitation, leaks, air ingress), and pneumatic faults; implement safe temporary work-arounds and permanent fixes.
• Quality & compliance : Complete batch records, maintenance logs, and calibration sheets accurately and on time.
• Follow GMP / ISO 13485-style practices and water standards for dialysis (e.g., ISO 23500 / AAMI) as directed by QA.
• Adhere to LOTO, chemical handling, confined space, and other EHS procedures; maintain 5S in utility and mixing areas.
• Coordination : Liaise with Chinese OEMs / suppliers for parts and technical support; manage spare-parts inventory and service kits.
• Provide on-call coverage for production and respond to critical alarms after hours when needed.
• Train operators on basic care and first-level troubleshooting.
