Continuous Improvement / Industrial Engineering Internship
About Us: Since 1935, we’ve been on a mission to bring a little extra happiness to everyday life and inspire connections over food. We select the finest ingredients the world has to offer, craft premium products made with love, and never settle for shortcuts. We believe that when we share our food, we share a part of ourselves — and that’s the only way we’d put our name on it.
Today, our small family company has grown into a national leader in specialty olives, peppers, and sauces under the leadership of CEO Jeff Mezzetta, and our commitment to quality has never wavered. With an 80-year legacy behind us and a bright future ahead, we’re seeking passionate, driven candidates to help us bring our cherished family traditions to a new generation.
The ideal candidate will have an immediate connection to our Core Ingredients:
Crunchy Crunchy: We are hungry for excellence.
Own It: We think and act as an owner – with appetite, initiative, and responsibility.
Connection: We build authentic relationships that foster trust and open communications.
Vibrance: We come to work eager and passionate about fulfilling our vision. When we share our work, we share a part of who we are.
Program Objective
The Continuous Improvement / Industrial Engineering Intern will develop hands-on experience in manufacturing performance analysis and process optimization by learning and applying Industrial Engineering methods focused on time study, cycle time, takt time, and line balancing. Throughout the duration of this 16 week program, the Intern will support Mezzetta’s effort to improve packaging line performance, reduce bottlenecks, and identify opportunities for efficiency and labor optimization.
By the end of the internship, the Intern will:
Understand and apply time study and work measurement techniques.
Calculate and interpret cycle time, takt time, and OEE-related metrics.
Identify bottlenecks and develop data-based process improvement proposals.
Demonstrate practical Lean problem-solving in a real production environment.
Present technical findings and communicate improvement ideas effectively.
