About the Position

Senior ML Engineer (d/f/m)

We offer a great vision and exciting challenges

We are a well-coordinated, interdisciplinary team of around 14 experienced colleagues who have successfully mastered one of the most complex challenges of our time: the development of a robot figure that looks like a living being, whose sympathetic presence touches people emotionally – and which is already having a successful impact in social work today. Our product is never finished: It is constantly being developed, regularly receives new functions and continues to grow in close cooperation with partners in the field. In this way, we are creating a product that provides relief and enhances the quality of social work – today in the care sector, tomorrow in many other areas of social work.

With over 60 robots sold and a broad response in media such as ARD, ZDF, ZEIT and Süddeutsche Zeitung, we are bringing social robotics into everyday reality. Studies prove the positive effect and evidence of our solution. This is reflected not only in public interest, but also in the growing sales funnel.

And that’s exactly why we’re looking for you!

Developments in the field of machine learning are so rapid and the potential for our social robot Navel is great. However, due to the diversity and complexity, it is not easy to always find the best sustainable solution for Navel and achieve its efficient implementation. That’s why we are looking for you to join our strong interdisciplinary team as an experienced ML expert.
