Job Title: Experience Maintenance Engineer

Location: Onitsha, Anambra

Employment Type: Full-time

Department: Engineering & Maintenance

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.

Requirements:

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.

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.

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.

Application Closing Date: 31st August, 2026.
