Numberly is recognized as one of the world's leading data marketing specialists with nearly 500 employees and 8 offices worldwide serving more than 500 blue-chip clients (L'Oréal, Sanofi, Moleskine, Campari, Nestlé, HSBC..). By putting technology to work for brands and consumers, Numberly is at the heart of business growth and everyone's desire for more responsible and relevant marketing. Numberly leverages the latest advances in data processing, analysis and activation, incorporating artificial intelligence technologies. This approach is part of a virtuous circle in which business competitiveness goes hand in hand with greater respect for privacy and data protection. Numberly helps customers collect, analyze and leverage their data across all marketing channels.

To do so, Numberly operates its own infrastructure, split over multiple datacenters. It gives us the ability to operate multiple distributed databases and process billions of events every day at scale while optimizing its cost and maintaining latency goals.

Our sustained growth pushes us to constantly challenge our technical and organizational choices. The DataOps team is mission critical at Numberly as it stands between our clients’ business contexts, our products delivery and the operational teams supporting them. As such, the team interacts with Project Managers, Project Owners and Data Engineers as well as Data Scientists. The team is responsible for ensuring that our Data platforms and technologies are reliable, performant and compliant with the highest security standards since they host our clients' critical data and jobs.

We need to solve complex problems in short windows of time, so we rely a lot on automation. We also love Open-Source software and we strive to redistribute to the community, make sure to check us out on GitHub!
