Reliability & Maintenance Engineer

DESCRIPTION Key Responsibilities

• Execute planned preventive maintenance (PPM) schedules for all refrigeration systems, including tropical rooms, chilled rooms, and frozen rooms.
• Monitor and maintain optimal temperature parameters across all cold chain zones in strict accordance with defined Standard Operating Procedures (SOPs).
• Conduct routine inspections of compressors, condensers, evaporators, expansion valves, and refrigerant piping systems.
• Ensure refrigerant levels are maintained within specified limits and perform periodic leak detection tests.
• Monitor and maintain defrost cycles, drain lines, and insulation integrity of all cold rooms.
• Coordinate with Original Equipment Manufacturers (OEMs) and third-party service providers for specialized repairs and annual maintenance contracts.
• Diagnose and resolve refrigeration system faults, including compressor failures, refrigerant leaks, thermostat malfunctions, and evaporator icing.
• Respond to temperature excursion alarms and execute corrective actions within defined response timelines.
• Troubleshoot electrical and control system faults in refrigeration panels, PLCs, and Building Management System (BMS) interfaces.
• Perform root cause identification for recurring equipment failures and implements verified permanent fixes.
• Maintain and monitor Diesel Generator (DG) sets, including fuel systems, coolant levels, battery health, and periodic load bank testing.
• Execute preventive and predictive maintenance on Uninterruptible Power Supply (UPS) systems, including battery health checks, load testing, and firmware updates.
• Monitor and maintain electrical panels — including Main Distribution Boards (MDB), Sub-Distribution Boards (SDB), Automatic Transfer Switches (ATS), and change-over panels.
• Conduct periodic insulation resistance (IR) testing, earth resistance testing, and thermography surveys of all electrical systems.
• Ensure full compliance with applicable electrical safety standards and statutory requirements.
• Monitor real-time equipment parameters through the BMS, temperature monitoring systems, and energy meters.
• Conduct daily walkthroughs to identify abnormalities, unusual sounds, vibrations, or visual defects in equipment.
• Track and maintain equipment runtime hours, energy consumption data, and performance trends.
• Ensure all monitoring sensors and alarm systems are calibrated and fully functional at all times.
• Daily Reports — Prepare and submit daily equipment status reports covering temperature logs, DG runtime, UPS status, and all observed anomalies.
• Weekly Reports — Compile weekly maintenance summary reports covering PPM compliance, breakdown analysis, spare parts consumption, and pending work orders.
• Monthly Reports — Develop monthly performance reports inclusive of equipment uptime percentage, Mean Time Between Failures (MTBF), Mean Time To Repair (MTTR), energy consumption trends, and cost analysis.
• Conduct structured Root Cause Analysis (RCA) for all equipment breakdowns, temperature excursions, and safety incidents using methodologies such as Five-Why Analysis and Fishbone Diagrams.
• Develop and implement Corrective and Preventive Actions (CAPA) with clearly defined timelines, responsible owners, and effectiveness verification criteria.
• Maintain a CAPA tracker with closure status, evidence of implementation, and effectiveness validation records.
• Present RCA and CAPA findings during Weekly Business Reviews (WBR) and Monthly Business Reviews (MBR).

Qualifications & Skills

• Education — Diploma or bachelor’s degree in mechanical engineering, Electrical Engineering, or Refrigeration & Air Conditioning.
• Experience — Minimum three to five years of hands-on experience in refrigeration systems and base building equipment maintenance.
• Technical Knowledge — Proficiency in refrigeration cycles, electrical systems, DG operations, UPS systems, and BMS platforms.
• Certifications — Preferred certifications in Refrigeration & Air Conditioning, Electrical Safety, or equivalent recognised standards.
• Analytical Skills — Ability to perform structured RCA, develop CAPA plans, and apply data-driven decision-making.
• Reporting Skills — Proficiency in preparing technical reports, dashboards, and MIS outputs using MS Excel and relevant tools.
• Communication — Clear verbal and written communication skills for effective cross-functional coordination. Working Conditions
• Shift-based operations with rotational shifts as applicable to site requirements.
• Sustained exposure to cold room environments, including frozen rooms operating at sub-zero temperatures.
• Regular work in proximity to live electrical systems — adherence to all safety protocols is mandatory.
• On-call availability required for emergency breakdowns and critical temperature excursion response. Key job responsibilities Key Responsibilities
