About the Job

Requirements

Proficiency with computerized maintenance management system (CMMS) or enterprise asset management (EAM) systems such as SAP Plant Maintenance, Maximo, or Fiix, and Excel; ability to build reports and dashboards.
Strong understanding of industrial manufacturing assets and utilities, including winding and pressing equipment, coating equipment, ovens, vacuum systems, HVAC, compressed air, chillers, and boilers.
Ability to read mechanical and electrical drawings, piping and instrumentation diagrams (P&IDs), and original equipment manufacturer (OEM) manuals, and convert technical information into executable job plans.
Working knowledge of predictive technologies, including vibration, infrared thermography, and ultrasound, and lubrication best practices.
Experience applying reliability and lean tools, including reliability-centered maintenance (RCM), total productive maintenance (TPM), 5S, Kaizen, and standard work.
Root cause analysis capability using methods such as 5 Why and fishbone/Ishikawa, and disciplined problem solving.
Familiarity with industry quality frameworks such as ISO 9001, AS9100, and ISO 13485, and good documentation practices.
Practical knowledge of lockout/tagout (LOTO), confined space, electrical safety and arc flash, and permit systems.
Effective stakeholder communication and negotiation to balance production priorities with maintenance risk.
Maintenance, repair, and operations (MRO) planning and vendor management skills, including bill of materials (BOM) accuracy, lead time mitigation, and cost/availability tradeoffs.

Responsibilities

Own the CMMS/EAM planning and weekly scheduling process for preventive, predictive, and corrective work in coordination with Production and EHS.
Develop clear job plans covering scope, labor, duration, skills, permits, LOTO steps, and quality assurance checks, and ensure accurate closeout documentation.
Create and maintain asset master data, preventive maintenance task lists, BOMs, and equipment hierarchies; keep routes and frequencies optimized.
Kit and stage materials, parts, tools, and permits; coordinate with Stores to maintain MRO spares availability and minimum/maximum levels.
Prioritize the maintenance backlog using risk, asset criticality, and production impact; manage ready-to-schedule status.
Plan plant shutdowns and maintenance windows, including critical path activities, contingencies, and contractor sequencing.
Coordinate OEMs and service contractors on scope, quotes, site access, safety orientation, and quality of work.
Monitor and report KPIs, including schedule compliance, PM completion, wrench time, MTTR/MTBF, and backlog health, and drive corrective actions.
Support reliability initiatives (RCM/TPM), PM optimization, and root cause analysis; capture lessons learned into standard work.
Ensure compliance with EHS and quality requirements, including LOTO, hot work, ESD handling, calibration/verification, and documentation.

As a Maintenance Planner for Knowles’ Cornell Dubilier, you will convert maintenance demand into safe, well‑sequenced plans and schedules that maximize equipment reliability, minimize downtime, and enable quality‑critical production for MedTech, Aerospace/Defense, Industrial, and Electrification customers.
