About Us

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.

We are a diverse team of 75+ 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.

Position Overview

As a senior software engineer, you will join our rewards data team to assist in building and maintaining user-facing and internal applications to support rewards reporting and financial performance monitoring. At Chorus One we take the upstream node software from projects like Ethereum, Solana, Cosmos, or Avalanche; compile it; run it on one of our servers; and then make sure it is reliable and secure, monitor it, and keep it up to date. The networks rewards us for that in their native token. Keeping track of those rewards over time is a hard problem, because ironically, blockchains typically don’t expose convenient APIs to extract this data in a useful format. This is why we build our own automation, and integrate with third-party data vendors. Your work will power internal reports and dashboards, as well as external customer reporting, and rewards data APIs.

Key Responsibilities

• 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.
• Support and collaborate. Review and discuss engineering designs, review code, help fellow engineers, and work with other teams such as platforms engineering, customer success, business development, and our networks team, to get them the insights they need.
• Innovation and continuous improvement. Seek to simplify, optimize, and secure our staking services and systems.
• Take part in on-call rotation approximately 2 days per month. You will be responsible for building APIs used by external parties, which come with an uptime requirement.

Job requirements

What we are looking for:

• 4+ years experience as a Software Engineer.
• Experience with operating and maintaining server-side software in production.
• Experience with Python (most of our rewards data automation is written in Python)
• Other backend software at Chorus One is written in a mix of Rust and Go, experience with these is an advantage.
• Experience using SQL databases, preferably PostgreSQL.
• Experience with implementing REST APIs.
• Strong communication skills and ownership to drive new features independently.
• Interest in blockchain technology, in particular distributed systems and consensus algorithms.
• You are able to work in the following time zone: Switzerland ± 6 hours.

By combining these improvements and routing the right data through optimized, low-latency paths, the DoubleZero protocol empowers blockchains and other systems to reach performance levels that are currently impossible.

In short, DoubleZero is a new Internet for distributed systems. It is supported by two organizations: DoubleZero Foundation, which drives the adoption, decentralization, security, and advancement of the protocol; and Malbec Labs, which develops the technical components of the protocol itself.
