Board of Directors

Jennifer Rumsey became the President and Chief Executive Officer (CEO) of Cummins Inc. on August 1, 2022. In this role, she oversees the strategic direction, growth initiatives and global operations for the +100-year old, Indiana-based company.

Rumsey has focused her 25-year career on advancing technology and bringing products to market that power customers’ success and make a positive difference in the world. She co-authored the Cummins’ Destination Zero strategy, the company’s strategy to go further, faster to reduce the greenhouse gas (GHG) and air quality impacts of its products and reach net-zero emissions by 2050.

Rumsey assumed the role of President and CEO in August 2022. She has served in several leadership positions across the company, including most recently as the President and Chief Operating Officer (COO).

Prior to that role, she led Components, one of Cummins’ five business segments. From 2015 to 2019, Rumsey was Cummins’ Vice President and Chief Technical Officer and led a global technical organization of approximately 11,000 employees responsible for research and engineering across the company. Rumsey’s early career focused on control systems and system engineering, initially at a fuel processing and fuel cell start-up company in Cambridge, MA. In 2000, she moved to Cummins and has worked in a variety of engineering roles across Cummins and product life cycle areas including advanced technology development, new product development, current product engineering and product quality.

Rumsey is on the Board of Directors of Cummins Inc. and Hillenbrand. She is a member of the Society of Women Engineers (SWE), the Society of Automotive Engineers (SAE), the Purdue Engineering Advisory Committee and Women in Trucking Association.

Rumsey holds a Bachelor of Science in Mechanical Engineering from Purdue University and a Master of Science in Mechanical Engineering from Massachusetts Institute of Technology.
