Roles & Responsibilities

Senior Manager Maintenance (Mechanical & Electrical)

Battery Cell Fabrication Plant

Position Purpose

Lead all Mechanical & Electrical (M&E;) maintenance activities for production equipment and systems across the entire battery cell fabrication plant. Ensure maximum equipment availability, reliability, and performance to support continuous, high-yield production, cell assembly, electrolyte filling, formation,

ageing, and related processes. Drive a proactive maintenance culture that minimises unplanned downtime, protects product quality, and fully supports “keeping the lines running.

Reporting & Scope

- Reports to Plant Head
- Owns end-to-end maintenance of all production machinery and associated M&E; systems (mixers,

coaters, dryers, calenders, slitters, stacking/winding machines, electrolyte fillers, formation equipment, conveyors, automation, robotics, etc.).
- Leads multi-disciplinary teams of maintenance engineers, supervisors, technicians, and specialists

(mechanical, electrical, instrumentation, controls, tooling) plus external contractors and OEMs.
- Works in close partnership with Production, Process Engineering, Quality, Utilities, EHS, and Planning.

Key Responsibilities 1. Preventive Maintenance (PM) Excellence

- Develop, implement, and continuously improve a comprehensive Preventive Maintenance programme

covering all production equipment.
- Establish time-based, usage-based, and condition-based PM schedules aligned with OEM

recommendations, process criticality, and failure-mode analysis.
- Ensure 100% on-time completion of PM tasks with high first-time quality.
- Integrate predictive maintenance techniques (vibration analysis, thermography, oil analysis, motor

current signature, ultrasonic, etc.) to move from reactive to proactive strategies.
- Maintain accurate digital maintenance records (CMMS/EAM system) and equipment history.

2. Corrective Maintenance & Breakdown Response

- Lead rapid, structured response to all equipment breakdowns and performance deviations.
- Establish clear escalation protocols, mean-time-to-repair (MTTR) targets, and 247 support coverage

for critical production lines.
- Drive rigorous Root Cause Analysis (RCA), 5-Why, Fishbone,



and Failure Mode & Effects Analysis

(FMEA) for every significant failure.
- Implement permanent corrective and preventive actions to eliminate recurring issues.

3. Periodic Checks of Machine Parameters & Process Capability

- Define and enforce routine verification of critical machine parameters (speeds, tensions, temperatures,

pressures, alignment, coating thickness controls, vacuum levels, dew-point interfaces, etc.).
- Establish standard checklists, frequency, acceptance criteria, and documentation for all key process

equipment.
- Partner with Process Engineering and Quality to ensure equipment remains within process windows that

protect cell quality and yield.
- Trend parameter data to detect early degradation and trigger proactive interventions.

4. Tooling Maintenance & Management

- Own the complete lifecycle of production tooling (dies, rolls, blades, fixtures, jigs, moulds, coating heads,

calendaring rolls, electrode tooling, etc.).
- Establish tooling inspection, sharpening/reconditioning, calibration, storage, and tracking systems.

1• Define tooling life standards, wear limits, and replacement/refurbishment criteria.
- Ensure quick-change tooling practices and minimise changeover-related downtime.

5. Full Support for Keeping the Lines Running

- Act as the primary technical partner to Production for achieving and sustaining target OEE, throughput,

and yield.
- Provide on-floor presence and rapid decision-making during production shifts, especially during

ramp-up, new product introduction, or process changes.
- Ensure maintenance activities are planned to minimise disruption (coordinated shutdowns, opportunity

maintenance during changeovers or planned stops).
- Maintain high equipment availability, recognising different failure modes and cleanliness/

moisture-sensitivity requirements.




- Support line balancing, bottleneck elimination, and continuous improvement projects that involve

equipment modifications or upgrades. 6. Asset Management, Spares & Cost Control

- Own the maintenance budget (labour, spares, contractors, tools, external services).
- Optimise spare-parts inventory using criticality analysis, min-max levels, and consignment where

appropriate.
- Manage OEM relationships, service contracts, and technical support agreements.
- Oversee equipment modifications, upgrades, and capital maintenance projects in coordination with

Engineering. 7. People Leadership, Safety & Compliance

- Build and develop a skilled, multi-skilled, and accountable maintenance organisation.
- Enforce strict safety standards (LOTO, permit-to-work, arc-flash, confined space, machine guarding, hot

work, etc.) and a strong safety culture.
- Ensure all maintenance work complies with electrical codes, pressure systems regulations, and internal

quality systems.
- Promote knowledge sharing, training, and succession planning within the team.
- Foster seamless collaboration with Production, Utilities, Quality, and Process Engineering.

8. Continuous Improvement & Digitalisation

- Lead reliability-centred maintenance (RCM), Total Productive Maintenance (TPM) pillars, and Lean

maintenance initiatives.
- Champion digital tools: CMMS optimisation, IoT sensors, predictive analytics, digital twins, and mobile

maintenance execution.
- Support new equipment installation, commissioning, FAT/SAT, and smooth handover to operations.

Key Competencies & Background (Recommended)

- Solid technical expertise in mechanical, electrical, and controls systems used in high-precision

continuous manufacturing (battery, semiconductor, film coating, or similar industries preferred).
- Proven experience leading large maintenance organisations in a 247 production environment.
- Hands-on familiarity with CMMS, predictive technologies, and reliability engineering tools.
- Excellent leadership, communication, and cross-functional influencing skills.
- Strong bias for action, data-driven decision making, and ownership of uptime.
