    Deine Rolle im Team

    • As the IT organization of REWE International, we work with more than 700 colleagues to build innovative IT products and services for our business units in Austria and across international markets--setting the pace for modern retail.
    • We are looking for a Java Backend / Python Developer who enjoys building robust, scalable backend systems and working with complex, data-driven platforms.
    • In this role, you will design and implement high-quality services and APIs, and work with a broad range of business and customer-related data across different domains.
    • Using Java and Python, you will develop backend services, process and enrich larger datasets, and contribute to a platform that supports CRM, customer analytics, and operational use cases, as well as spatial and location-related scenarios where relevant.
    • A key focus is to design solutions that are scalable, reusable, and well prepared for future analytics and AI use cases.
    • You will collaborate closely with stakeholders across IT and business and support requirements engineering where needed.
    • You will report directly to the CPO and work in a high-ownership setup without a dedicated team, where initiative, technical excellence, and hands-on problem solving make a real difference.
    • You support the full software development lifecycle -- from designing and modeling required components to implementing and customizing software solutions.
    • You build high-performing, scalable backend services using Java (Spring Boot) and/or Python, ensuring technical robustness and long-term maintainability.
    • Through thoughtful design and continuous optimization, you ensure our IT solutions are future-proof and ready for long-term, international use.
    • Together with your colleagues, you align code architecture and API/interface contracts across teams and products, and document solutions in a clear and traceable way.
    • You critically evaluate technical decisions and provide constructive feedback on their impact on structure, performance, reliability, and business/system logic.
    • You actively contribute to evolving our engineering and quality standards -- from clean code practices and automated testing to CI/CD and delivery pipelines.
    • Working closely with your team, you help drive the technical modernization of our product and platform.
