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.

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

Your team is writing and maintaining a GPU based cryptographic library. You will contribute in making it fast. This library is indeed intended for growing with new cryptographic algorithms. Your main tasks would be to:

• write high performance code on GPUs,
• improve existing GPU code to make it faster,
• learn from cryptographers that are part of your team,
• share knowledge about GPU programming with the team.

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

He / She / They should:

• solid background in GPU programming (CUDA),
• into open sourcing,
• willing to discover cryptography,
• team player,
• communication skills.
