Maintenance Engineer
Main Responsibilities
- Preventive Maintenance (PM)
Execute and continuously optimize equipment preventive maintenance plans based on equipment characteristics, manufacturer recommendations, and historical failure data.
Complete scheduled equipment inspections, maintenance, lubrication, calibration, functional testing, and replacement of critical components, ensuring PM quality and timely completion rates.
Identify potential equipment hazards discovered during PM execution, and promptly formulate and track corrective actions.
Regularly evaluate the effectiveness of PM strategies and optimize maintenance cycles, maintenance content, and critical spare parts configuration.
- On-site Repair and Troubleshooting
Go deep into the production site to independently undertake fault diagnosis and repair of filling machines, capping/pressing machines, labeling machines, boxing/cartoning equipment, conveying systems, and related automation equipment.
Respond quickly to equipment failures, completing problem localization, repair, and functional recovery in mechanical, electrical, and automation aspects to reduce downtime.
Perform root cause analysis for major, complex, or repetitive failures, using tools such as 5Why and Fishbone diagrams to develop long-term solutions.
Conduct risk assessments and tracking for temporary repair measures, ensuring timely completion of permanent rectifications to avoid recurrence of failures.
- Equipment Reliability and Improvement Projects
Analyze equipment downtime, failure frequency, and performance loss to identify improvement opportunities affecting safety, quality, efficiency, and reliability.
Lead or participate in equipment modification, automation optimization, tooling improvement, and small-scale technical projects, including solution evaluation, risk analysis, installation and commissioning, acceptance, and handover.
Enhance equipment stability, changeover efficiency, ease of operation, and safety and quality assurance capabilities through technical improvements.
Track the implementation effects of improvement projects, create standardized documents, and promote the application of successful experiences to similar equipment.
- Safety and Quality Management
Strictly abide by company EHS and quality management systems, executing relevant safety requirements such as Lockout-Tagout (LOTO), work permits, and risk assessments.
Ensure that equipment safety protection, interlocks, and critical functions remain complete and effective after repair and modification, and do not bypass safety or quality controls with temporary measures.
Support investigations into deviations, quality events, and equipment-related abnormalities, and implement corrective and preventive actions related to equipment.
Ensure that maintenance activities comply with GMP and site hygiene requirements to prevent contamination or quality risks to products, equipment, and the production environment during the maintenance process.
- Technical Documentation and Maintenance Data Management
Timely and accurately record work orders, failure causes, repair measures, spare parts usage, and equipment downtime information in the CMMS or related maintenance systems.
Establish and maintain equipment technical archives, maintenance records, key parameters, drawings, and related technical data.
Participate in the formulation and updating of equipment maintenance standards, inspection standards, SOPs, and One Point Lessons (OPL), and provide necessary technical training for maintenance technicians and operators.
Assist in spare parts identification, technical verification, safety stock optimization, and localization/substitution assessment of critical spare parts.
- Cross-functional Collaboration
Work closely with Production, Quality, EHS, Engineering, and Supply Chain teams to coordinate maintenance windows and improvement project implementation, minimizing the impact on production plans.
Provide technical support to operators regarding correct equipment usage, daily inspections, and basic maintenance.
Communicate technically with equipment suppliers and external service providers, tracking problem resolution, repair quality, and project delivery.
