Senior Engineer - Rust

In this role, you will be responsible for designing and developing Ockam's open source Rust Library, Command Line, and Packages.

Ockam crates implement a collection of messaging and cryptographic protocols that provide end-to-end application layer trust in data. We believe that, in order to have a realistically manageable vulnerability surface, all modern applications need end-to-end guarantees of data integrity and authenticity. The only way to build secure and private applications is to remove unnecessary implicit trust in network boundaries, intermediaries and infrastructure.

This role will require solving challenging problems in areas like library API design, type systems, protocol design, actor model, async execution, abstraction, loose coupling, pluggable modules and more. You will be part of a team of senior engineers who have deep expertise across distributed systems, messaging protocols, network protocols, cryptographic protocols, embedded systems etc.

The Ockam team is passionate about making powerful cryptographic protocols simple and safe for application developers. In this role you will collaborate with this team to deliver safe, secure, stable, well-documented, easy to use, 100% open source Rust libraries and command line.

We just raised a Series A and will be growing the team from 11 to 30 over the next two years. 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.
Ockam is a distributed, remote-first team with a headquarters in San Francisco California.
