With a strong focus on innovation, efficiency, and quality products, Our team shows up every day to serve our customers and vendors with focus, ingenuity, and a commitment to quality. Each and every one of our employees is an integral part of our operations, and part of what makes J&O Plastics leaders in precision injection molding. We strive to create an inclusive environment that celebrates our different lived experiences, with the hope of fostering a community atmosphere.

J&O Plastics is seeking a hands-on Production Supervisor to lead an assigned second- or third-shift injection molding production team.

You are responsible for the people, decisions, execution, and output of your shift. Your job is to execute directives, lead your crew, and exercise sound judgment as the senior leader in the building. This role carries more autonomy than most supervisory roles, and we want someone who sees this as an opportunity.

The successful candidate is a visible, consistent floor leader who keeps control of the operation, makes timely decisions, coaches employees, and delivers results without compromising safety or quality. Supervisors who execute consistently and develop their teams are our pipeline for senior production leadership.

PRIMARY RESPONSIBILITIES

• Direct injection molding production across 45 presses ranging from the assigned shift.

• Execute mold changes and changeovers to established setup standards, minimizing downtime between runs.
• Identify and resolve schedule risks, staffing shortages, equipment problems, and material concerns early.
• Recognize strong performance and address performance concerns promptly.
• Apply company policies fairly and consistently
• Maintain a professional, respectful, and accountable workplace culture.
• Deliver a complete handoff to the incoming Shift Leader .
• Escalate significant concerns to the Senior Production Management.
• Sustain 5S, standard work, and visual management on your shift — the audit should look the same at 3 AM as it does at 10 AM.

JOB REQUIREMENTS

• Three to five years of manufacturing leadership, team-lead, or production supervision experience.
• Demonstrated ability to lead employees and execute production requirements in a fast-paced environment.
• Comfort operating with autonomy — Discern when decisions are made without escalation and when made with escalation.
• Working knowledge of 5S, Lean manufacturing, standard work, visual management, or similar systems.
• Experience using root-cause methods such as 5-Why, 8D, DMAIC, fishbone, or corrective action systems.
• Experience monitoring production measures such as output, downtime, scrap, labor utilization, efficiency, and first-time quality.
• Strong communication, decision-making, prioritization, and conflict-resolution skills.
• Ability to stay organized and decisive during production interruptions.
• Comfortable with production systems, manufacturing software, spreadsheets, and shift reporting.
• High school diploma or equivalent.

STRONGLY PREFERRED

• Injection molding, plastics, or high-volume manufacturing experience.
• Familiarity with molding process parameters and common defects (short shots, flash, sink, warp).
• Prior off-shift leadership experience.

• Lean, Six Sigma, or continuous improvement training — Relevant experience required, certification a plus.
• Technical training, manufacturing certifications, or a related degree.
