About the company
Leading European company in the retail sector, with a strong international presence and a well-established omnichannel model that seamlessly integrates physical stores and large-scale e-commerce operations.
In recent years, the organization has made a significant investment in technology, building an international tech hub in Barcelona from which strategic initiatives are being driven to support millions of users across multiple countries. This hub brings together multidisciplinary teams (engineering, product, UX, architecture) working in agile environments with a high degree of autonomy.
The environment is particularly attractive for tech profiles as it combines:
Real user scale and technical complexity
Projects with direct business impact
Modern technologies and advanced architectures
An international and collaborative setting

From a cultural perspective, it offers a dynamic and flexible environment, where not everything is predefined and individuals are expected to actively contribute to shaping the way of working and the team culture.
