Karriereseite und Stellenangebote – BJ Automotive

At BJA, the advantages of lean and manageable structures are consistently applied. BJA provides one-stop solution from Design to Manufacturing. BJA is perfectly positioned to provide reliable and cost-effective R&D and manufacturing services to global automotive brands.

BJ Automotive GmbH

BJ Automotive emerged from the separation of the automotive division of the Busch-Jaeger Elektro GmbH, a subsidiary of the ABB Group. Busch-Jaeger's automotive activities began in the 1970s with the first series deliveries of high-performance ignition systems to Audi AG.

In the following years, a powerful corporate unit evolved as a result of Busch-Jaeger’s distinctive electromechanical expertise and their special know-how in the switch and push-button segments.

Since 2006, BJ Automotive is a fully integrated subsidiary of Defond. Our company group has extensive experience in product development and manufacturing of electromechanical and electronic switches, modules, sensors, battery packs, and other innovative HMI. This creates all the conditions for a successful future for BJ Automotive.
