Job Expired

The Reliability Engineer (Mechanical / Electrical) is responsible for improving and sustaining the reliability, availability, and performance of mechanical and electrical assets across the process plant. The role provides technical leadership to Junior Reliability Engineers and Lube Technicians and ensures effective execution of condition monitoring, lubrication, and defect elimination activities. Reporting to the Condition Monitoring Specialist (Expert), this position translates condition monitoring data into engineering actions and long-term reliability strategies aligned with Life Cycle Asset Management (LCAM) principles.

Key Responsibilities

Implement and support Life Cycle Asset Management (LCAM) processes.
Develop and refine Asset Maintenance Plans incorporating: Preventive maintenance, Predictive and condition-based maintenance, Risk-based reliability strategies
Conduct equipment criticality assessments.
Lead Root Cause Failure Analysis (RCFA) and defect elimination initiatives.
Develop engineering solutions to repetitive failures affecting safety, production, cost, or compliance.
Apply value analysis to repair/replace and redesign decisions.
Provide reliability governance for crushers, SAG and ball mills, conveyors, pumps, thickeners, flotation cells, filters, gearboxes, and rotating equipment.
Analyse bearing failures, seal failures, misalignment issues, and lubrication deficiencies.
Review mill girth gear lubrication systems, spray patterns, and trunnion seal performance.
Oversee alignment programs and rotating equipment reliability improvements.
Validate condition monitoring findings and define corrective maintenance strategies.
Analyse reliability of motors, MCC’s, VSD’s, transformers, switchgear, protection systems, and control equipment.
Investigate motor failures, electrical trips, and recurring faults.
Develop preventive and predictive maintenance strategies for electrical assets.
Support thermography and motor testing programs.
Ensure compliance with statutory electrical requirements.
Supervise Junior Reliability Engineers and Lube Technicians in execution of: Vibration monitoring, Oil analysis, Ultrasonic testing, Thermography, Lubrication routes and contamination control
Ensure accurate data collection, reporting, and escalation of findings.
Analyse monitoring data and convert findings into actionable work scopes.
Optimise lubrication strategies to extend equipment life and reduce failures.
Provide daily supervision, mentoring, and performance management of Junior Reliability Engineers and Lube Technicians.
Ensure workload planning and task prioritisation aligns with plant criticality.
Develop competency and training plans for reliability personnel.
Promote cross-disciplinary collaboration between mechanical and electrical teams.
Foster a strong safety-first culture within the reliability function.
Participate in equipment specification reviews and commissioning activities.
Develop acceptance testing criteria for new installations.
Support supplier evaluation and technical assessments.
Drive continuous improvement initiatives aimed at: Increasing MTBF, Reducing MTTR, Eliminating recurring defects, Improving lubrication compliance rates
Utilize CMMS (Pronto / SAP / equivalent) to: Track reliability KPI’s, Monitor failure trends, Manage defect elimination actions
Maintain structured reliability reports and technical documentation.
Present findings and improvement recommendations to the Condition Monitoring Specialist and maintenance leadership.
