Full Stack Generalist needed!

Preventai AB

Do you want to be part of one of Sweden's fastest-growing start-ups? Antrino Labs is a vision infrastructure company. We build AI architectures that let cameras understand actions, behavior, and context across time — moving video beyond surveillance into real-time, programmable sensing. Instead of cameras just recording video in the background, they can now perform tasks in real-time: detecting theft, identifying security risks, analyzing flows in stores and industries, and enabling organizations to act immediately when something happens. Video goes from being something reviewed in retrospect to becoming active, real-time decision support. This means that millions of existing cameras, which previously only functioned as passive sensors, can suddenly start working actively for businesses – from retail and logistics to security companies and public environments. Everything is built on a foundation of Privacy by Design, where data protection and GDPR compliance are central parts of the architecture. The goal is to make advanced video analysis both powerful, scalable, and responsible in how data is handled. We just closed our Seed Investment Round which was announced together with Dagens Industri and are scaling up to meet demand. Also, the company is certified through Institution för Strategiska Produkter which makes the company a strategic asset for the Kingdom. Purpose and Goal We are looking for exceptional Fullstack Engineers who want to be part of our journey in automating detection.
