There are many companies that work in English - being the second largest exporter in the world, Germans do a lot of trade with people in countries that tend not to speak German, hence the global language of business (English!) is used.
My company for example organises B2B events for different industries, and we work with partners from all over the world. One example would be our events for the automotive industry, where we have people from Japan, the U.S., South Africa, the whole of Europe, and many more getting involved.
Right now we are actually looking for some English speakers for our sales team. If anyone is interested, send an e-mail with CV and cover letter to
