The Concrete Framework division is writing and maintaining several open-source cryptographic libraries and tools dedicated to Fully Homomorphic Encryption (FHE). Those libraries and tools are written with different languages (rust for libraries, cpp for the compiler, python for frontend, etc…) and is targeting several environment (linux/macos/…) and/or hardware (cpu/gpu/…). As example one of those libraries, Concrete-core is used as the backbone of the whole framework. It implements various cryptographic primitives. The codebase uses the Rust programming language as its main language, but it is expected to host hardware-specific code written in other languages in the near future.

Open-source cryptographic libraries are subject to high expectations in terms of continuous integration and deployment. The correctness of the implementation must be thoroughly tested on several pieces of hardware, and contributions must meet various criteria of quality in order to be merged. Moreover our different modules (libraries or tools) are highly dependent and we must ensure that any improvements and moreover security updates of any piece of our framework is updated in the whole framework. We already have a good system in place, but there is still room for improvements to bring our architecture to the level we intend!

We are looking for new CICD Engineers to join our team and work on our ambitious project!

We are looking for a candidate who will help us upgrading our pipelines to the level of quality expected for a major cryptographic framework. Among other topics, you will have to:

• ensure the consistency of our continuous integration pipeline,
• design and maintain automatic releases systems for the different module of our framework : rust crates on crates-io (and potentially other repositories), python on pipy, cpp libraries, …
• setup benchmarking and testing systems for various (potentially exotic) pieces of hardware and deployment software,
• setup automatic delivery system for the different kinds of documentation for the library,
• increase the number of automatic quality check to ensure the best possible quality of contribution.

Note that full remote is possible, however we ask for the possibility to visit our Paris office at least on a quarterly basis.
