Equipment Reliability & Maintenance

• Perform advanced troubleshooting and resolve electrical, mechanical, pneumatic, hydraulic, and automation-related failures.
• Maximize uptime for critical equipment and meet key maintenance KPIs (MTBF, MTTR, OEE).
• Develop, execute, and continuously improve preventive and predictive maintenance plans (e.g., vibration analysis, thermography, and failure analysis).
• Conduct root-cause analyses (RCA, 5 Whys, Ishikawa) and implement robust corrective and preventive actions.

Automation & Controls

• Troubleshoot and program PLCs at a basic to intermediate level (Siemens/Allen-Bradley).
• Manage industrial communication networks, including Ethernet/IP, Profinet, CAN, and Modbus.
• Configure drives, servo motors, sensors, HMIs, and industrial safety systems.
• Interpret and update electrical schematics, P&IDs, and pneumatic diagrams.

Mechanical & Industrial Systems

• Maintain and optimize mechanical systems, including transmissions, actuators, bearings, alignments, torque specifications, vacuum systems, pumps, and chillers.
• Diagnose mechanical failures related to vibration, temperature, noise, or abnormal behavior.
• Replace, adjust, and evaluate wear and tear on critical machine components.

Projects & Continuous Improvement

• Lead improvement projects focused on efficiency, automation upgrades, safety, and downtime reduction.
• Collaborate with integrators, OEMs, and suppliers for troubleshooting and system upgrades.
• Document equipment modifications in accordance with quality standards (ISO 9001 and IATF 16949 preferred).
• Support engineering change processes (ECR/ECN).

Safety & Compliance

• Ensure compliance with OSHA, NFPA 70E, ISO standards, and machine-safety regulations (EN/ISO 12100, 13849).
• Participate in risk assessments, Lockout/Tagout (LOTO) procedures, safety audits, and 5S/6S activities.
• Implement engineering controls to proactively reduce operational risks.

Production Support

• Provide direct, hands-on support during critical equipment failures and production ramp-ups.
• Train and mentor maintenance technicians on advanced troubleshooting and repair methodologies.
• Ensure equipment consistently meets cycle time, quality, and performance requirements.

Who You Are:

Education

• Bachelor's degree in Mechatronics, Robotics, Electrical Engineering, Mechanical Engineering, Industrial Engineering, or a related field.

Experience

• 25 years of experience in the maintenance of automated manufacturing equipment.
• Hands-on experience with automated assembly equipment, robotics, End-of-Line (EOL) testing, and servo-driven systems.

Technical Skills

• PLCs: Siemens TIA Portal, Allen-Bradley Studio 5000.
• Industrial Electrical Systems: 480VAC, 24VDC controls, and interpreting electrical schematics.
• Sensors: Inductive, optical, laser, pressure, temperature, and vision systems.
• Mechanical Systems: Pneumatics, hydraulics, alignments, torque, fittings, and tolerances.
• Software: Proficiency with CMMS software (MaintainX preferred).
• Documentation: Ability to read and interpret technical manuals fluently in English.

Soft Skills

• Strong sense of urgency and ownership over equipment performance.
• Excellent problem-solving and analytical skills.
• Effective communication skills for working seamlessly with cross-functional teams.
• Ability to work effectively under pressure in time-critical manufacturing situations.
• Proactive mindset with a strong continuous-improvement mentality.
