  • Monitor incoming product quality to ensure size, color specifications (bleached/unbleached), and moisture levels meet established standards.
  • Inspect finished packaged products for appearance, coding accuracy, print quality, and seal integrity.
  • Monitor package weights and make adjustments as necessary to achieve product weight targets and minimize giveaway.

Why Work Here?

This opportunity offers a stable role in a large, well-established production facility where safety, quality, and teamwork are highly valued. You will work with modern packaging technology, build in-demand technical skills, and have consistent opportunities for overtime during peak seasons. The environment supports continuous learning, cross-training, and professional development, providing a strong foundation for long-term growth in manufacturing and operations.

Work Environment

The role is based in a clean nut processing facility situated on more than 15 acres, with an average workforce of around 350 employees. The environment can be very loud due to extensive machinery, and team members should be comfortable working in a high-activity production setting. Work schedules run Monday through Saturday, with an expectation to work six days per week and mandatory overtime averaging approximately 48 to 55 hours during harvest season. Shift assignments are based on seniority, and candidates must remain flexible, as they may work any of the three shifts: 1st shift from 6:00 AM to 2:30 PM, 2nd shift from 2:00 PM to 10:30 PM, or 3rd shift from 10:00 PM to 6:30 AM.
