Full Stack Developer

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. In this role, you will work across both frontend and backend systems, building the core product experience that allows users to connect cameras, deploy intelligence, and interact with real-time insights from video streams.
The role is broad and hands-on, where you will work closely with our engineering team and leadership to develop a scalable, high-performance platform that can support thousands of live video streams and global deployments. You will help shape both the user-facing interfaces and the underlying backend systems, ensuring the platform remains intuitive, fast, and reliable as we expand.

Developing and maintaining scalable backend services and APIs that power the platform
Collaborating closely with designers and engineers to create intuitive, high-performance product experiences
Ensuring the platform remains fast, reliable, and responsive as the number of users, cameras, and data streams grows
Writing clean, maintainable, and well-structured code while following modern development best practices
Participating in system architecture discussions and helping design scalable solutions for complex problems
Troubleshooting and resolving bugs, performance issues, and production incidents across the stack
Collaborating with DevOps and AI engineers to integrate machine learning systems and real-time data pipelines into the product
Continuously improving the developer experience, tooling, and internal workflows to accelerate development and product delivery
Contributing to code reviews, technical discussions, and knowledge sharing within the engineering team
Helping shape the technical direction of the platform as we scale globally and expand the product capabilities
Who are we looking for?
Strong experience as a Full Stack Engineer, preferably working on complex, production-grade applications
Solid experience building modern web applications, including both frontend and backend systems
Proficiency with JavaScript/TypeScript and modern frameworks such as React, Next.js, or similar
