Department: Engineering & Maintenance
Experience Level: Mid-to-Senior level (4+ Years)
Reports To: Head of Engineering / Plant Manager
Job Summary
The Maintenance Engineer will be responsible for ensuring the maximum uptime, reliability, and optimal performance of all plant machinery, with a primary focus on injection and blow moulding equipment. This role demands a highly skilled, hands-on technical professional who can execute preventive maintenance programs, lead rapid troubleshooting initiatives, and minimize production downtime.
The ideal candidate must bring a deep mechanical and electrical understanding of moulding technologies, alongside the operational agility required to handle complex machinery configurations safely and efficiently.
Key Duties and Responsibilities
Machinery Maintenance & Reliability
- Execute and optimize both scheduled preventive (PM) and corrective maintenance programs for all injection and blow moulding machines, ensuring minimum disruption to active production runs.
- Troubleshoot and repair complex mechanical, hydraulic, pneumatic, and electrical faults on manufacturing equipment, including proportional valves, pumps, clamping units, and heating zones.
- Diagnose and service auxiliary equipment such as chillers, air compressors, material hoppers, granulators, and robotic take-out arms.
Hands-on Machine Operation & Setup Support
- Safely operate and test injection and blow moulding machines post-repair to verify process parameters, calibration, and structural stability before handing them back to production.
- Assist the production team during complex mould installations, ensuring correct alignment, precise clamping force, and seamless integration of utility lines (water, air, oil).
- Monitor machine efficiencies and implement modifications or calibrations to improve cycle times and reduce energy consumption.
Spare Parts & Asset Management
- Manage the inventory of critical engineering spares for moulding machines, identifying consumption trends to prevent stockouts of vital components.
- Maintain comprehensive, detailed records of all maintenance activities, equipment breakdowns, root-cause analyses (RCA), and repair costs in the engineering log.
Safety, Health & Environmental Compliance
- Enforce rigorous Lock-Out/Tag-Out (LOTO) protocols and other industrial safety standards during all maintenance interventions.
- Keep the workshop and machine maintenance areas organized, clean, and fully compliant with factory safety regulations.
JOB SPECIFICATION
Experience & Technical Expertise
- Proven Experience: A minimum of 4+ years of verified hands-on experience as a maintenance technician or engineer strictly within a plastics manufacturing or automated moulding environment.
- Moulding Mastery: Demonstrated, deep experience in troubleshooting and maintaining Injection Moulding and Blow Moulding machines (e.g., Engel, Husky, KraussMaffei, Haitian, or similar brands).
- Operational Handling: Direct experience in handling and operating moulding machinery to effectively test, calibrate, and validate mechanical repairs.
Educational Background & Academic Qualifications
- Minimum Requirement: Bachelor’s Degree (BSc) or Higher National Diploma (HND) in Mechanical Engineering, Electrical/Electronic Engineering, Mechatronics, or a highly relevant engineering discipline.
- Professional technical certifications or specialized training in industrial hydraulics, pneumatics, or PLC automation will be a strong advantage.
Key Competencies & Expected Professional Qualities
- Diagnostic & Root-Cause Analysis Skills: Exceptional ability to systematically trace and diagnose erratic mechanical or electrical failures under tight time constraints.
- Blueprint & Schematics Literacy: Highly proficient in reading and interpreting complex hydraulic circuits, pneumatic diagrams, and electrical wiring schematics.
- Automation & PLC Knowledge: Basic to intermediate understanding of PLC systems (e.g., Siemens, Allen-Bradley) for fault-finding via machine interfaces and control screens.
- Precision & Quality Focus: Meticulous attention to detail, ensuring alignments, torque values, and temperature calibrations exactly match manufacturer specifications.
Soft Skills & Operational Attributes
- Problem-solving under Pressure: A calm, structured approach to high-stress emergency breakdown situations on the production floor.
- Teamwork & Communication: Strong collaborative skills to work effectively alongside the production manager, machine operators, and external service vendors.
- Shift Flexibility: Willingness to work flexible hours, including rotational shifts or being on-call to support a 24/7 continuous manufacturing cycle.
