What this role is
Experienced technician who performs advanced maintenance and repair on engine room and plant equipment with minimal supervision. At the Senior Support Specialist (S3) level, the role owns escalated / complex cases, complex or non-standard cases, and drives resolution quality on the team's hardest cases. Guides junior support informally.
What this level does
- Diagnose and repair moderately difficult breakdowns across mechanical, electrical, hydraulic, pneumatic and control systems, using judgment to decide repair-vs-replace and sequencing without daily instruction.
- Assist the Plant Maintenance Lead and Plant Supervisor with planning of repair jobs and special projects — estimating parts, downtime windows and design/layout — then physically executing the work.
- Read and interpret complex technical schematics to trace faults through control and power circuits on heavy mining equipment.
- Perform corrective and preventive work independently on non-routine equipment, coordinating with operations to schedule downtime and confirm the machine is safe to work on.
- Monitor equipment condition and log findings so recurring failure patterns become visible, contributing input to the plant PM schedule.
- Knowledge applied
- Detailed knowledge of plant maintenance procedures across multiple disciplines, sufficient to perform non-routine diagnosis and repair and to read complex schematics.
- Complexity & problem solving
- Makes judgments on moderately difficult breakdowns — repair vs replace, sequencing, downtime trade-offs — with little instruction on daily work.
- Collaboration & interaction
- Coordinates repair tasks and downtime with operations and the Lead; substantial procedural understanding, no formal leadership.
- Typical experience
- 2–4 years; skilled multi-craft technician, journey-level trade.
Skills at this level
- CMMS Work-Order Execution
- — Receives, actions and closes preventive and corrective work orders in the plant's Computerized Maintenance Management System, recording parts used, labor time and repair notes so equipment history stays accurate and usable.
- Technical Schematic Interpretation
- — Reads mechanical, electrical, hydraulic, pneumatic and control schematics to locate components and trace faults through power and control circuits on plant and mining equipment.
- Preventive Maintenance
- — Performs scheduled lubrication, adjustment, inspection and component replacement on running equipment so small mechanical or technical problems are caught before they become major failures.
- Equipment Defect Inspection
- — Examines parts and assemblies for breakage, excessive wear and abnormal condition during inspections, and documents findings to trigger corrective action.
- Broad Multi-Discipline Maintenance
- — Applies a skill set spanning mechanical, electrical, hydraulic, pneumatic and control systems — from welding and wiring to hand tools and hydraulics — to diagnose and repair diverse plant equipment.
- Heavy Mining Equipment Repair
- — Maintains and repairs drills, loaders, conveyors and utility systems, including installing wire, connecting power sources and restoring equipment to safe running condition.
- Breakdown Diagnosis
- — Isolates the root cause of moderately-to-highly complex faults across interacting systems and decides repair, replacement or modification and the safe sequence to execute it.
- Repair Job Planning
- — Assists in planning repair work and special projects by estimating parts, design/layout and downtime windows, and coordinating the shutdown so work fits the operational envelope.
- Reliability-Centered Maintenance
- — Applies RCM principles to decide which failure modes warrant planned intervention, shaping PM routines and job plans for a specialty equipment area.
- Predictive Maintenance / Condition Monitoring
- — Uses condition-monitoring and IoT-based techniques to detect degradation early and shift a specialty area from reactive repair toward planned, forward-looking intervention.
- Energy Consumption Optimization
- — Monitors facility energy use, maintains energy-recovery systems and improves equipment efficiency to support plant sustainability targets in energy/mining operations.
- Spare Parts Inventory Judgment
- — Recommends spares and stocking levels for specialty equipment, balancing the downtime risk of a stockout against carrying cost.
- Working Lead / Peer Coaching
- — Assigns and checks the work of less experienced technicians on repair jobs and shutdowns, and trains peers on diagnosis and repair methods for difficult equipment.
