Fullstack Engineer (m/f/d)


Digital communication between companies and customers is outdated and complicated. We at Flexperto are working on changing that. Everything that your sales employees have done so far offline, is now also available online with Flexperto. Set up customer appointments, clarify questions in the video chat, edit documents, co-browse websites, sign contracts or say “hi” to customers through WhatsApp.

We have gained considerable momentum in the last 3 years. Among our customers are international players in the insurance and banking sector. Our 30 employees are mainly located in Berlin.

We are further developing our instant messaging experience, which aims to centralize WhatsApp, Telegram & Co. in one single, enterprise-grade omnichannel messenger. Therefore, we are looking for Fullstack Engineer (m/f/d) to strengthen our team.
