Industrial Maintenance Technician – Electrical & Mechanical

MTNA•Rancho Cucamonga, CA

1d•Onsite

About The Position

Eternity Systems/MTNA, Inc. operates an industrial service center specializing in the washing and processing of reusable plastic containers. Our Rancho Cucamonga facility operates 24 hours a day, six days per week. The Maintenance Department supports operations across all shifts, with technicians assigned to each shift along with Maintenance leadership and administrative support. Preventive maintenance is scheduled with a focus on completing thorough maintenance on individual machines while minimizing operational disruption. Eternity Systems/MTNA, Inc. is seeking an experienced, hands-on Industrial Maintenance Technician with strong electrical troubleshooting capabilities to support our 24-hour industrial wash operation in Rancho Cucamonga. We are looking for a self-starter with solid knowledge of industrial electricity, including three-phase systems, AC/DC circuits, industrial voltages, current, frequency, power, harmonics, and leakage current. The ideal candidate will also be comfortable working across mechanical systems, welding/fabrication, and forklift maintenance. This position requires someone who can independently identify electrical and mechanical problems, troubleshoot equipment to the root cause, safely complete repairs, and communicate clearly with Operations regarding equipment status and repair timelines. The right candidate will not wait for equipment to fail. We need someone who takes ownership of preventive maintenance, identifies potential issues early, and works collaboratively with Maintenance and Operations to keep equipment operating safely and reliably. We are specifically looking for someone who is electrically strong, proactive, dependable, safety-focused, and hands-on. The successful candidate should be comfortable walking the facility, identifying potential equipment issues before they result in downtime, and taking ownership of repairs from diagnosis through completion. This is not a position where the technician simply replaces parts based on instructions. The successful candidate should be able to diagnose why an electrical or mechanical failure occurred, identify the appropriate repair, safely complete the work, test the equipment, and communicate the outcome to Operations. Electrical troubleshooting capability will be a key consideration during the interview and selection process and may be evaluated through technical interview questions or a practical skills assessment.
