Data Engineer

The AI & Data Engineering team is one of the newest additions at Infinum, focused on delivering impactful solutions in data engineering and artificial intelligence. We work on a range of client projects, helping turn data into real business value.

Our work spans everything from building robust data pipelines to developing AI-powered systems that extract insights and enable smarter decision-making. Right now, we’re building machine learning algorithms that recommend relevant content to users of an IoT app, along with data pipelines that power analytics and ML models behind the scenes.

As a growing team, we’re looking to significantly expand in the near future. We often collaborate with DevOps, Backend, QA, and System Architect teams and have delivered data-based solutions for industries like smart devices, hospitality, and healthcare. If you’re excited by complex challenges, enjoy collaborating across disciplines, and want your work to make a real impact in industries that matter, come build with us. We’re growing fast, learning faster, and always up for a cup of coffee and a great idea.
