JOB DESCRIPTION
As a Software Engineer, you work on digital solutions that directly support how organizations operate, decide, and grow. You design and build reliable software for a wide range of projects, from backend services and APIs to web and mobile applications, always with a focus on quality, maintainability, and real user value.
You work in multidisciplinary teams together with Data Scientists, Cloud Engineers, and UX Designers. You take responsibility for your part of the solution, understand the customer’s context, and translate requirements into robust, future-proof software. Rather than being tied to one framework or language, you focus on solving the right problem in the right way.
You continuously reflect on your work and actively look for ways to improve both the solution and the way the team works. Knowledge sharing, collaboration, and craftsmanship are key. Your contribution helps shape intelligent digital solutions that combine technology, data, and user experience.
You report to the Service Line Manager of the Intelligent Solutions department. Depending on your experience, you operate at Junior, Medior, or Senior level, with clear expectations and room to grow in responsibility and impact.
