• Schedule and assign daily tasks, set priorities, and evaluate results in collaboration with supervisors and planning partners.
• Maintain accurate production, inventory, and process records using electronic MRP systems and document management tools.

• Strong safety mindset and comfort working in a regulated manufacturing environment with strict sanitation and documentation requirements.

• Ability to communicate clearly, provide feedback, and support team performance on a night shift.

• Forklift or pallet walker experience (training provided on-site if needed).
