Software Engineer Internship

Numberly is recognized as one of the world's leading specialists in data marketing with nearly 500 employees and 11 offices worldwide serving more than 300 leading clients (L'Oréal, Arte, Groupe Seb, Pernod Ricard, SNCF, Aigle, HSBC...). By putting technology at the service of brands and consumers, Numberly is at the heart of the growth of companies and the aspiration of everyone for a more responsible and relevant marketing.

Numberly relies on the latest advances in data processing, analysis, and media activation in a virtuous context combining competitiveness of companies and enhanced respect for privacy and data protection.

Our sustained growth pushes us to constantly question our technical and organizational choices. We must solve complex problems in short time frames, which is why we rely heavily on automation. We are also passionate about open source: as we depend on it a lot, we strive to contribute back to the community.

To do this, Numberly has always mastered, developed, and operated its own on-premise technical platforms thanks to the expertise of its internal teams without overlooking the cloud when it is relevant. From development to datacenter hosting, through network connectivity, everything is thought, built, maintained, and secured by our teams and we are proud of it.

The NMP team is a multidisciplinary team composed of developers (full-stack, backend, and frontend), product owners, UX/UI designers, and product support specialists. It is responsible for the development and maintenance of the Numberly Mar Tech Platform, a complete suite of applications designed to create and analyze campaigns on all digital channels, including emails, SMS, push notifications, Facebook, and many others.

With the stability and maintainability of our product being at the heart of our concerns, we place great importance on the quality of our code, the constant updating of our technical stack, and the efficiency of our processes.
