Staff Engineer - Messaging Systems in Elixir

Ockam is how distributed applications have end-to-end encrypted, trustful communication. This is an exciting and challenging role on the Ockam Team. Ockam is building open source, end-to-end encrypted and mutually authenticated messaging libraries and infrastructure that is designed for the high throughput, low latency, intermittent connectivity requirements of IoT and connected machines. We use Elixir to design the core of our messaging infrastructure - Ockam Cloud. In this role, you will be responsible for building a modular Elixir library with a strong emphasis on loose-coupling and developer-friendly APIs. We also use Elixir as our bridge to several enterprise systems and this role will involve designing integrations with several external messaging systems and cloud services. We use Rust to implement the cryptographic primitives in Ockam and our Elixir library uses our Rust library via Erlang NIFs. Designing efficient, fault tolerant NIFs will be interesting challenge in this role. Cryptographic protocols are utilized throughout the Ockam stack, so whether this is an area of experience or experimentation in your past, you will be challenged. Ockam is a small and extremely senior team. This role involves architecture, interface design, writing code, responsibility for testing, and publishing documentation. Everyone on the Ockam team takes responsibility for their parts from end-to-end, including the creation of long term objectives, issues in GitHub, task management, and summaries of key results.
