The position acts as the operational lead for the section, escalating only matters of strategy, capital, and major variations to the Engineering & Project Manager.

Key Responsibilities:

Maintenance Planning and Execution:

•  Approve the Preventive Maintenance Schedule (PMS) prepared by the Maintenance Planner and ensure its execution across both teams.

• Review weekly and monthly KPI dashboards prepared by the Data Administrator (engineering) and the Maintenance Planner; agree on improvement actions.
• Submit weekly, monthly, and quarterly maintenance reports to the Engineering & Project Manager — covering performance, work completed, costs, risks, and recommendations.
• Provide inputs to Quarterly Business Reviews (QBR) and other management reporting cycles.

Budget and Cost Control:

• Manage the operational budget allocated to the Maintenance Section, ensuring spend is tracked daily against approved plans (zero underspend / zero overspend principle).
• Approve parts requisitions, contractor work orders, and minor expenditures within delegated authority limits.
• Monitor and report on cost-per-operating-hour and other unit-cost metrics; identify cost reduction and efficiency opportunities.
• Escalate budget variances and capital requirements to the Engineering & Project Manager.

Spare Parts, Tools, and Inventory:

• Coordinate with the Storekeeper, Maintenance Planner, and Data Administrator to ensure availability of critical spare parts and consumables.
• Approve MIN/MAX stock levels, reorder points, and critical-spares strategy.
• Oversee accountability and calibration of workshop tools and diagnostic equipment.

Safety, Health, Environment and Compliance:

• Enforce strict compliance with HSSE policies, lock-out/tag-out (LOTO) procedures, hot work permits, confined-space procedures, and safe work practices across the section.
• Lead incident, near-miss, and hazard reporting and ensure investigations are conducted with corrective actions tracked to closure.
•  Ensure waste oils, used filters, and other hazardous materials are managed in line with environmental procedures.
• Champion a strong safety culture through visible leadership, coaching, and recognition.

Continuous Improvement and Workforce Development:

•  Identify and lead improvement initiatives that reduce downtime, improve reliability, extend asset life, or reduce cost.
•  Drive adoption of best practices, OEM updates, and lessons learned from incidents and breakdowns across the section.
• Plan and oversee training, upskilling, and certification of maintenance staff in collaboration with HR and the Engineering & Project Manager.

Stakeholder Coordination:

• Liaise with the Production team to align maintenance windows with operational priorities.
