Full Stack Engineer, Developer Experience & Product Platform

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.

📈 Who We Are: We are rebuilding the energy transaction, making it transparent and fair. Our goal is to put power back where it belongs, in the hands of customers and to take on one of the most critical problems of our century, access to low cost electricity. tem exists to fix a broken global energy market that’s long favoured legacy operators, intermediaries, and opaque pricing. Today’s electricity system was not designed for rapid decarbonisation, AI-driven efficiency or fair access for the actual users - businesses and generators. We’ve built the first AI native transaction infrastructure to reinvent how electricity is bought, sold and priced. Our technology is designed to cut out the inefficient fees, automate complex market flows, and bring transparency and fairness to energy transactions at scale. In late 2025, after extraordinary growth, we closed a $75 million Series B - led by Lightspeed Venture Partners with participation from Albion, Atomico, Allianz, Hitachi Ventures, Hitachi Ventures, Schroders Capital and others - positioning us for global expansion, deeper product innovation and category leadership. We’re scaling internationally and building toward a future where AI-driven infrastructure is foundational to electricity markets worldwide. Since launch, our modern utility product, known as RED, has already facilitated thousands of business customers and billions in energy transaction value, proving that modern software and AI can transform an industry built on legacy systems. At tem, we’re not just building another energy company, we’re rearchitecting market infrastructure so that transparency, efficiency and sustainability become the default, not the exception. 🏅 THE ROLE: We’re looking for Senior Full Stack Engineers to design and build the systems that power tem's core products and internal platforms.
