Applied Cryptographer - Rust

Ockam is designing open source protocols and libraries for end-to-end encrypted communication for highly distributed, complex, connected systems. In this role, you will be responsible for the architecture and design of cryptographic protocols within Ockam. Our goal is to make our cryptographic libraries easy to use correctly and hard to misuse, you will lead the design of these library APIs in Rust. This is an applied cryptography role which will involve researching and applying robust, peer reviewed, cryptographic primitives to the design of our protocols. The role will also involve implementing cryptographic primitives and protocols in Rust. You will also get to work with Rust FFI and our C and Elixir libraries. You'll have the chance to design protocols for - Secure Channels, Authenticated Key-Exchange, Anonymous Credentials, Key lifecycle, Authentication, Authorization etc. Interesting cryptographic building blocks that you would get to dive deep into and apply to real-world problems will include - Bi-linear parings, Zero knowledge proofs, Noise Framework, Sigma Protocols, Signature schemes like BBS+, Secure Multi Party Computation etc. Ockam is a small and extremely senior team. This role involves architecture, interface design, writing code, responsibility for testing, and publishing documentation.
