What this role is

Senior individual contributor who leads hands-on maintenance and troubleshooting of engine room and plant equipment, including nuclear systems, ensuring safe and reliable operations. At the Principal Support Specialist (S5) level, the role owns function-wide support practice, program-level and systemic support problems, and drives support strategy across the function. Subject-matter authority; shapes the practice.

What this level does

Serve as the plant's go-to specialist on a critical equipment class or discipline (e.g., conveyor drives, high-voltage/control, hydraulics), resolving the complex failures others cannot and setting the repair standard.
Contribute to the creation and refinement of PM routines, work-order procedures, and CMMS job plans for the specialty area so the whole crew executes to a consistent method.
Establish spare-parts and inventory recommendations for the specialty equipment, balancing downtime risk against stock cost.
Apply predictive/condition-monitoring techniques and reliability-centered maintenance principles to shift the specialty area from reactive repair toward planned intervention.
Act as working lead and technical trainer for peers and less experienced technicians, facilitating execution on major shutdowns and coaching on diagnosis of difficult faults.

Knowledge applied: Deep specialist expertise in a specific equipment class or discipline; contributes to creating PM routines, job plans and reliability techniques within that area.
Complexity & problem solving: Resolves the most complex and recurring failures; develops improved methods and applies predictive/RCM concepts to prevent recurrence.
Collaboration & interaction: Acts as working lead and technical trainer, facilitating peer execution and providing guidance; influences maintenance standards for the crew.
Typical experience: 6+ years; recognized expert in the specialty within plant maintenance.

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.

Pay across the ladder

Plant Maintenance (Energy/Mining) — median with , by . Real canon data.

National-base pricing — this family's function differential is pending review, so dollar levels are not function-adjusted (level-over-level % is unaffected).

Pay figures are modeled estimates from our market equation — level-differentiated, with honest-wide bands. They refresh as new leveling evidence lands; treat per-role dollars as directional.

How to read this profile

Every number here is traceable — to a named source, a stated method, and an as-of date — and each value is labeled by how we know it: observed from data, computed by a model, projected forward, or governed canon. Nothing is a black box, and nothing is invented to fill a gap.

The principles behind the numbers

Ranges, not false precision

Pay is P10 · median · P90, never a single misleading number.

Three honest states, never a fake %

Role matches resolve to confident / review / no-match — a calibrated verdict, not a made-up percentage.

Provenance on every value

Each number carries whether it's observed, computed, projected, or canon — so you always know how much to lean on it.

Gaps shown as gaps

When a figure isn't available at the grain you need, we say so — we don't fabricate a number to fill the cell.

Frozen, versioned editions

Pay and coordinate editions are pinned, so a comparison you make today still means the same thing next quarter.

Privacy by min-N

Any aggregate over people is suppressed below a minimum count, so no individual is identifiable.
