Senior AI Engineer

We at Antrino Labs believe that every physical square meter can be programmed.

Instead of cameras just recording video in the background, they can now perform tasks in real-time: detecting thefts, 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 are proud to have closed our Seed Round which was announced by Dagens Industri as well as being backed by Microsoft, Nvidia and EuroHPC.

We are looking for an AI Engineer who wants to be part of our journey. In this role, you will work on the core intelligence layer of our platform, developing and integrating AI systems that transform video streams into real-time insights and actionable outputs.

Today, parts of our AI stack are rapidly evolving as the platform scales. As we grow, you will play a central role in designing, building, and optimizing AI pipelines, integrating machine learning and video understanding models, and ensuring our systems operate reliably and efficiently in real-world environments.

The role is highly technical and hands-on, where you will work closely with our AI, computer vision, and platform teams to build scalable intelligence systems capable of processing thousands of live video streams in real time. You will help design and improve the architectures, inference pipelines, and data workflows that power our platform, ensuring our AI systems remain robust, efficient, and production-ready as we expand globally.

• Developing and integrating foundation models, LLMs, and video-language models that transform video streams into real-time insights and actionable outputs
• Designing the intelligence layer that translates natural-language behavior definitions into reliable, structured model outputs
• Fine-tuning, prompting, and evaluating multimodal models for video understanding, event detection, and intelligent automation
• Building evaluation and continuous-improvement pipelines that measure and raise model quality against real-world production data
• Optimizing model inference for low-latency, GPU-accelerated processing of live video streams at scale
• Experimenting with and integrating state-of-the-art AI techniques across language, vision-language, and temporal reasoning
• Monitoring model behavior in production and iterating based on real-world feedback and system metrics
• Contributing to the architecture and technical direction of the platform's AI stack as we scale globally

• Strong hands-on experience with foundation models, LLMs, and NLP — fine-tuning, prompting, evaluation, and production deployment
• Experience with multimodal or vision-language models; temporal video understanding is a strong plus
• Ability to turn natural-language intent into reliable, structured model behavior through prompt engineering, fine-tuning, and evals
• Experience serving models at scale using Sglang, vLLM, or similar high-performance inference frameworks
• Understanding of GPU-accelerated inference and cost/latency trade-offs in production
• Experience integrating AI systems into scalable production infrastructure rather than isolated research environments
• Strong problem-solving skills and comfort owning model direction across multiple AI domains
• Excellent communication skills in English, both written and spoken; Swedish is a plus

We believe you are a team player with a strong work ethic, who thrives in a fast-paced environment where you build something from the ground up together. You have a positive attitude towards problem-solving and always deliver high quality in your work, while being curious about how processes can be improved and streamlined.

You enjoy solving problems and see opportunities where others see obstacles. In a rapidly growing company, things often change – therefore, you thrive in an environment where initiative, responsibility, and structure are important qualities. You have the ability to work independently, prioritize correctly, and manage several tasks or projects in parallel.

With us, you will be part of a culture where we value intellectual curiosity, high pace, and collaboration between technology and business. We build advanced technology but believe in simple, clear ways of working and a team where everyone contributes to the whole. This means we are looking for people who not only want to do their job – but who also want to help build structures, improve processes, and participate in shaping how the company develops going forward.

Form of employment: Full-time

Start date: Immediately

Location: Blasieholmsgatan 2A, Stockholm

Our recruitment process is simple and transparent. We review applications continuously and contact candidates we assess to be a good match for the role.

The process usually consists of a first conversation where we get to know each other and go through your background and the role in more detail. This is followed by one or two in-depth conversations where we discuss experience, working methods, and how you could contribute to the team.

In the final stage, we may also ask for references. Our goal is for the process to be efficient, clear, and respectful of your time, while ensuring that both you and we feel it is the right match.

We look forward to your application!
