Senior Software Engineer with Rust (Urbit Team)

Mar 14
$90K – $130K
Fully Remote

Chorus One is one of the leading operators of infrastructure for Proof-of-Stake networks and decentralized protocols. Tens of thousands of retail customers and institutions are staking billions in assets through our infrastructure helping to secure protocols and earn rewards. Our mission is to increase freedom and speed of innovation through decentralized technologies.

Red Horizon is the Urbit arm of Chorus One. Broadly, we aim to support the growth of peer-to-peer networks, to expand the freedom and sovereignty that human beings experience in their digital lives.

We are a diverse team of around 60 people distributed all over the globe. We value radical transparency, striving for excellence and improvement while treating each other with kindness and generosity. If this sounds like you, we’d love to hear from you.


As a Senior Software Engineer, with Rust knowledge, you will be an integral part of our Red Horizon software engineering team. Red Horizon is our one-stop-shop for hosting Urbit ships. For users, it offers a portal where users can use Urbit and develop their own Urbit, and check the status of their Urbit ships. On the backend, we have a platform that automatically launches, manages, and monitors these ships.

Red Horizon consists of a NodeJS API frontend and a backend written in TypeScript and Rust. It is backed by Supabase and Hashicorp Vault, and runs on Google Cloud, with many bandwidth-intensive parts running on bare metal.

Your main role will be to design, develop, and deploy software systems to advance our hosting product.


  1. Design and develop new features. Discuss with internal stakeholders to clarify how our next feature should look, discuss with fellow engineers how it should be implemented, and then drive implementation to completion.

  2. Support and collaborate. Review and discuss engineering designs, review code, help fellow engineers, and mentor them on a technical level.

  3. Innovation and continuous improvement. Seek to simplify, optimize, and secure our staking services and systems.

The “Senior” title on the job description is purely for describing the experience level of the hire we’re looking for. Out job titles don’t include hierarchical seniority systems and we use consensus for driving decisions.
