We are hiring.
We have operated as a minimal, engineer-centric small team until now. We are currently actively recruiting not only for our product development department (ML Engineers, Application Engineers) but also for the business side (Growth, New Business Manager).
We warmly welcome applications from individuals who resonate with our mission to reduce crime globally—a cause of significant social importance—or who are interested in the challenge of developing new ventures. These ventures will leverage crime prediction technology, previously accessible only to law enforcement agencies, to introduce predictive analytics and optimization into the security business domain.
