Over the past few years, FERMAX has built a comprehensive digital ecosystem on which our Connected Product operates. This project has fully immersed us in the world of IoT (**Internet of Things**), cloud-based **services infrastructure** (specifically Azure), and **microservices-based development**. Our Connected Product enables users worldwide to answer calls received on their video intercoms directly from their mobile devices—responding and unlocking doors regardless of location. But this is only the tip of the iceberg. We are working to lead the electronic door entry telecommunications sector, and many additional services remain to be developed to deliver added value to our users. You will join Fermax at the moment of greatest technological change and disruption in its last 40 years—the ideal time to learn and grow together. Profile: MOBILE SOFTWARE ENGINEER Experience: At least two years Job Description You will join FERMAX’s mobile development team, primarily working with **Flutter**. You will collaborate closely with your backend, frontend, and DevOps colleagues within agile, project-based squads, ensuring smooth integration of new features across the entire system. Under the supervision of our **Engineering Manager**, and in coordination with the **Product Owner**, you will plan and prioritize backlog tasks.
