By doing so, we hope to open up the field of vision-based AI for new applications and for organizations that previously couldn’t use AI-powered technology as it was too expensive for them or because they lacked the technical know-how needed to develop an AI-solution from scratch.

As a workplace, we can offer you the opportunity to work on the cutting edge of AI in a startup environment, where you help us build a product from the ground up while being part of the core team with a voice in what we should do next.

• Ability to work independently and take ownership of tasks

What we offer:

• Competitive package with equity and a sizeable learning budget that you can spend as you wish to develop yourself
• A real problem to solve with the potential of having a real impact on the world around us
• A startup environment with flat hierarchies
• Support from a WATTx, a Berlin-based company builder, offering you the security and support of a larger organization
• Workplace flexibility - Home-office, remote, adjustable working hours - we place our trust in you being the best person to plan your workweek
• A great place for the intellectually curious, as we are sharing offices with other startups in the AI landscape
