In 1989, Jauslin and two partners founded
Jost Wohlen AG, a firm specializing in electrical systems, telematics, and automation. Until today he is the controlling shareholder and managing director of the company. Since 2011, he is also the chairman of Jost Aarau AG, which acts as a subsidiary. Between 1993 and 2011 he served as an expert of the final exams for the electrician apprentices (VAEI). His companies currently employ about 35 people and therefore is a typical Swiss
SME. Jauslin currently serves as vice president of the founding committee of the Development Foundation Technopark Aarau and executive director of the Athleticum Niedermatten Wohlen Association. == Politics ==
