We are seeking an experienced, hands-on 3rd Shift Maintenance Supervisor for our plant in Rialto, CA. Reporting directly to the Maintenance Manager, you will lead and support our night-shift Maintenance Mechanics.

• Follow Safety & Quality Rules: Enforce plant safety, OSHA, FDA, SQF, and HACCP regulations at all times.
• Manage Projects: Complete equipment installations and in-house repair projects from start to finish.
• Maintain Standards: Communicate shift updates, issue disciplinary actions when necessary, and report directly to plant management.

What We Are Looking For

• Experience: 4+ years as a maintenance supervisor or manager in a manufacturing environment (food plant experience preferred).
• Technical Skills: Strong industrial mechanical and electrical experience. Skilled with forklifts, scissor lifts, hand tools, and high-speed machinery.
• Language: Bilingual (English / Spanish) strongly preferred. Able to read, write, and speak clear English for safety rules, communication, and reporting.
• Safety & Quality Knowledge: Basic knowledge of OSHA, SQF, HACCP, and food safety standards.
• Work Ethic: Punctual, dependable, and able to work independently or direct a team on the plant floor.
• Education: High school diploma required; Bachelor's degree or trade certifications a plus.

• PTO
• Company holidays
• 401k with employer match
