We're not looking for a buddy. We're looking for a leader - someone who commands respect, holds the line, and drives a floor to perform at its best every single shift.

THE ROLE This isn't a role for someone looking to be popular. This is a role for someone who thrives on structure, takes accountability seriously, and gets results through discipline and clarity, not always through consensus. You'll own the production floor. Standards are set. Expectations are high. Your job is to make sure they're met, every day, no excuses.

THE PROFILE OF A FLOOR COMMANDER

• Authoritative presence - people know where they stand with you
• Non-negotiable on standards - 5S, safety, output, no exceptions
• Decisive under pressure
• Comfortable with hard conversations - accountability over comfort
• Data-driven operator - tracks KPIs, spots problems early
• Command and clarity - instructions are heard and followed

WHAT YOU'LL OWN

• Lead and supervise a team of production workers - set expectations and hold them
• Drive daily, weekly, and monthly production targets with zero tolerance for preventable failures
• Enforce 5S principles (Sort, Set in Order, Shine, Standardize, Sustain) and enforce them consistently
• Conduct safety audits, address hazards immediately, and maintain a culture where safety is non-negotiable
• Run shift communications: production logs, KPI tracking, updates to management - nothing falls through the cracks
• Oversee workforce training so every employee knows their role and performs it properly
• Coordinate with maintenance to keep equipment running and downtime minimal
• Implement company Quality Assurance Procedures and Departmental Work Instructions to the letter
