Team & Context:

You’ll be part of the Datalayer team, a team of 8 people mainly based in Paris.

Our team is part of the Platform Technologies group which aims to address the technical and technological challenges of the MX.3 platform.

One of its goals is to provide the financial developers with robust and highly efficient SDKs to abstract the supported relational databases (Oracle, PostgreSQL, …) in both Java and C++.

The Java one heavily relies on the Hibernate third party which is a well-known JPA implementation.
