Zama is a cryptography company building open source homomorphic encryption tools for developers. Our technology enables a broad range of use cases, from confidential smart contracts to encrypted machine learning and privacy-preserving cloud applications. 🔒 Zama was founded by Pascal Paillier and Rand Hindi, and has more than 60 researchers and engineers in its team. 💪

Our teams are writing and maintaining several cryptographic libraries and tools dedicated to Fully Homomorphic Encryption (FHE). The codebase uses Rust as its main language 🦀, and it is expected to host hardware-specific code written in other languages in the near future.

Our cryptographic libraries are subject to high expectations in terms of safety and performance. We must:

• correctly implement FHE algorithms;

• reduce the attack surface;

• provide user-friendly interfaces;

• offer the best performance possible;

In this role you will:

• Implement cryptographic algorithms with the help of researchers at Zama;

• Make the library fast, reliable, and polished;

• Design efficient and user-friendly APIs;

• Improve the performance of the library with hardware or software optimizations;

• Benchmark and test the various cryptographic operations;

• Ensure the quality of the library delivery with continuous integration;

• Provide support to users by answering GitHub issues and forum topics.

• Serious Rust background;

• Experience with at least one of: Ocaml/Haskell/Scala/C++/C;

• Be into open source;

• Be interested in cryptography;

• Have good communication skills.

Embracing a flexible remote working ethos, Zama values in-person interactions and as such, requires a visit to our Paris headquarters at least once every quarter.

At Zama, innovation isn’t just a buzzword – it’s our DNA. If you’re passionate about cryptography, and are eager to shape the future of privacy, we welcome you to be a part of our journey. 🤗
