About the job

This is an exciting and challenging role on the Ockam Team. Ockam is building open source, end-to-end encrypted and mutually authenticated communication protocols and libraries that can work in resource constrained, intermittent connectivity IoT devices and connected machines.

We're using Rust to build the core cryptographic and messaging capabilities of Ockam. The role will involve building easy to use APIs and modular structure for – our actor framework, routing protocols, cryptographic protocols for secure channels, privacy preserving credentials, messaging abstractions like streams, topics, queues and more.
