VAARHAFT is a young startup that deals with the authentication of digital media. In an age of publicly accessible generative AI, creating deepfakes has become child's play, meaning that the authenticity of digital images and videos can no longer be blindly trusted.
Our mission is to preserve the credibility of digital media and protect companies from fraud involving manipulated images, videos, or documents with our solutions. We are active in all industries where the credibility of digital images is essential. Among other things, we prevent image-based insurance fraud and uncover document forgeries in the banking sector.
As a Backend Developer (f/m/d), you will play an important role in direct product development and work at the heart of VAARHAFT to realize our vision. You will work on our main product, the “Fraud Scanner,” ensure the smooth live operation of the API, and continuously develop it further. If you want to contribute your motivation and innovative ideas for the protection of credible digital media, you've come to the right place.
