Job description

Requirement:

You have prior experience supervising a shift in a plastic injection molding facility.

Your shift rhythm (schedule)

• Hours: 3:45pm to 12:15am
• Standard: 8-hour shift

A day in this role

You kick off the shift by reviewing the master schedule and aligning technicians, material handlers, cell leaders, and operators. You verify every work center is running the right job with approved cycle sheets, then walk the floor to check parts, adjust priorities, and remove roadblocks. When unplanned downtime or scrap pops up, you mobilize troubleshooting, document process changes, and ensure IQMS entries (downtime and scrap codes) are made promptly. Throughout the night, you facilitate quick stand-ups on safety, quality, and reliability, coordinate tooling and maintenance work orders, and keep communication flowing to the next shift so production, quality, and delivery targets hold steady.

What you’ll own

• Lead, train, coach, and develop team leaders, cell leaders, operators, and material personnel to meet company objectives.
• Translate the master schedule into daily production, secondary operations, and rework plans; ensure production and quality commitments are met.
• Hit and exceed shift metrics: scrap, utilization, and standard attainment.
• Confirm each press runs to standard cycles, allowable scrap, work instructions, and the quality plan; ensure timely entry of downtime and scrap codes in IQMS.
• Inspect product for conformance and direct support teams on machine adjustments as needed.
• Set and sustain safety, quality control standards, daily priorities, housekeeping, and a clean, organized work environment.
• Foster strong employee relations; apply company policies consistently and fairly; conduct performance reviews and drive development actions.
• Champion Quality and Environmental Policies and Procedures.
• Coordinate priorities across technicians, material handlers, and leads; drive troubleshooting and problem-solving aligned to the production plan.
• Run team meetings covering safety, quality, and equipment reliability.
• Oversee start-ups and quality checks: limit sample approvals, machine start-up verification, and prompt response to quality notices.
• Schedule and track tooling and equipment usage, repair, and maintenance; submit and follow up on maintenance/tooling work orders.
• Assign and monitor preventive mold cleaning for all production presses per procedure and schedule.
• Ensure purge procedures and line clearances are performed per work instructions.
• Train production staff on 5S, quality standards, SOPs, work instructions, accurate floor dispositions, MRB procedures, and data collection/reporting.
• Log any deviations from standard processes, including process changes; follow the escalation path.
• Provide clear shift-to-shift handoffs on production status, quality concerns, and pending actions.
• Recruit and mentor promotable talent; provide required documentation to the Production Manager and/or HR.
• Drive continuous improvement using a team-based approach: 5S, one-piece flow, and root-cause analysis.
• Model a positive, can-do mindset that builds teamwork, trust, accountability, and open communication.

Tools & technologies
