Contexte et atouts du poste

We are hiring talented sofware engineers, to build a new platform for mobile and edge computing, offering unprecedented capabilities of consistent data access at the edge and on the move.

The Concordant Vision

Concordant is an innovative Backend-as-a-Service (mBaaS) platform that makes it easy to develop powerful mobile apps that are liberated from the cloud. It is based on powerful concepts from cutting-edge research, enabling seamless offline operation, realtime peer-to-peer collaboration, and strong confidentiality.

The core of Concordant rests on a highly-available, geo-distributed, database management system using CRDTs, i.e., convergent data types. The CRDT concept is widely adopted in academia and industry to make systems more resilient to failures and highly available (our team is led by the inventors of CRDTs). The system can be replicated in different topologies, on edge devices, mobile devices, points-of-presence, and/or the cloud. It maintains consistency tailored to the application's requirements. Concordant provides application developers with a framework and API that make the development of advanced mobile applications development easy and hassle-free.

Concordant represents the maturation of many years of advanced research.
