we support employee growth and development. Guided by our culture principles, our teams work together to deliver value for customers and make a positive impact in the communities where we operate. We are an equal opportunity employer committed to fostering an inclusive workplace where everyone has the opportunity to grow and contribute. We offer competitive compensation and benefits, performance‑based incentives, flexible work arrangements, and development opportunities.

Our humble roots date back to 1927, where, in the back of a garage on Chicago’s northside, our founder, Edward Sundt, developed a small, fast‑acting, protective fuse for use in sensitive test meters. Sundt wanted to call his new company producing these small fuses, “Little Fuse,” but wasn’t allowed to trademark two such common words. So, instead he went with the one‑word, misspelled “Littelfuse.” For more than 95 years, Littelfuse has pioneered innovative products that help empower a sustainable, connected, and safer world. With the ever‑evolving electrification and electronification of customer applications, our product technologies are closely linked to sustainable applications such as electric vehicles and EV charging infrastructure, renewable energy and energy storage, factory automation, power management and more. Throughout our history, our people have been the foundation of our success — and that remains true today. Now more than ever, our bright and talented people are a strategic advantage for the company. From the production line to the engineering lab, the office or distribution center, Littelfuse people are an important part of a diverse, talented team of the best and brightest in the industry. While Littelfuse has experienced tremendous growth in recent years, we still maintain a small‑company, entrepreneurial approach where your efforts will drive our culture, our business, and the overall success of the organization. No matter where you work or what you do, your contributions will make a difference at Littelfuse — everywhere, every day.
