Full Time Irving TX, Irving, TX, US

Precinmac is a leading supplier of mission-critical, precision machined components used in the aerospace and defense, semiconductor, and automation equipment sectors.

We specialize in manufacturing uniquely designed high tolerance precision machined components and assemblies, with a focus on continuous improvement, on-time delivery, and the highest possible quality and consistency.

We are looking for an experienced facilities manager to keep us driving the future for our Texas based manufacturing locations.

The Maintenance Manager is a critical leadership role responsible for the operational integrity of AS9100-certified precision manufacturing facilities serving aerospace, defense, and space customers. This individual leads all maintenance and reliability activities for a fleet of 130+ CNC machines — including EDM, turning centers, 4-axis and 5-axis milling machines, coordinate measuring machines (CMMs), and assembly workstations — while ensuring compliance with the stringent quality, safety, and traceability requirements of the aerospace and defense industry.

The Maintenance Manager develops and drives a culture of planned, preventive, and predictive maintenance, minimizing unplanned downtime and protecting production schedules that support mission-critical programs. This role partners closely with Manufacturing, Quality, Engineering, and Operations leadership to deliver equipment reliability metrics that directly impact on-time delivery and AS9100 compliance.

KEY RESPONSIBILITIES

Maintenance Operations & Equipment Reliability

• Oversee all maintenance activities across 130+ CNC machines including EDM (sinker and wire), turning/lathe centers, 4-axis milling machines, 5-axis milling machines, CMM inspection equipment, and assembly support systems.
• Design, implement, and continuously improve a comprehensive Preventive Maintenance (PM) program covering mechanical, electrical, hydraulic, pneumatic, and coolant systems for all production equipment.
• Drive adoption of Predictive Maintenance (PdM) strategies — vibration analysis, thermal imaging, oil analysis, and spindle monitoring — to reduce unplanned failures and extend machine life.
• Ensure rapid response and resolution of unplanned breakdowns to minimize production disruption; establish and track Mean Time to Repair (MTTR) and Mean Time Between Failures (MTBF) KPIs.
• Manage facilities maintenance for HVAC, compressed air systems, electrical distribution, coolant/filtration systems, overhead cranes, and forklifts.
• Coordinate with OEM vendors and field service engineers for major machine rebuilds, spindle replacements, control upgrades, and specialized repairs.
• Lead, mentor, and manage a team of maintenance technicians; assign work orders, provide technical guidance, and conduct performance reviews.
• Identify training needs and develop technical skills within the maintenance team, including CNC controls (Fanuc, Siemens, Heidenhain), PLC troubleshooting, and machine tool systems.
• Establish on-call and emergency maintenance coverage protocols to support production operations across all shifts.
• Foster a safety-first culture; ensure all team members follow LOTO/TAGOUT procedures, PPE requirements, and OSHA standards at all times.

AS9100 Compliance & Quality System Integration

• Maintain full compliance with AS9100 Rev D quality management system requirements as they apply to equipment maintenance, calibration, and process control.
• Manage the equipment calibration program for CMMs, gauges, torque tools, and measuring instruments in coordination with the Quality department; ensure traceability to NIST standards.
• Author, maintain, and improve maintenance work instructions, SOPs, and equipment records in support of internal and external AS9100 audits.
• Support non-conformance investigations (NCRs/CARs) related to equipment and process failures; participate in root cause analysis (RCA) and corrective action planning.
• Maintain accurate maintenance records,…
