Inside Sales Intern

As a part of the global industrial organization Marmon Holdings—which is backed by Berkshire Hathaway—you’ll be doing things that matter, leading at every level, and winning a better way. We’re committed to making a positive impact on the world, providing you with diverse learning and working opportunities, and fostering a culture where everyone’s empowered to be their best.

What You’ll Do:

As an Inside Sales Intern, you’ll work closely with our Inside Sales Department on continuous improvement initiatives, gaining hands-on experience in sales operations, data analysis, and process optimization. This internship offers the opportunity to contribute to meaningful projects while learning how sales processes drive business success.

Your primary project will focus on aligning miscellaneous (MISC) charges across Marmon IEI facilities. You’ll be part of a cross-functional team tackling a real-world business challenge — simplifying and standardizing how different facilities handle costs such as testing, engineering, lot fees, logistics, shipping materials, returns, and storage.

You will research the history of these charges, compare practices across multiple facilities, identify best practices, and help develop a standardized approach for consistent application. Your efforts will directly support improved cost visibility, streamlined operations, and better decision-making for leadership.

Through this internship, you’ll gain practical experience in business process improvement, data-driven decision-making, and inside sales operations while collaborating with cross-functional teams to drive meaningful organizational change.
