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 70+ 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.

• Contribute to upstream software to improve observability, and build monitoring tools from scratch where none exist. The teams that build the node software are not the teams that operate this software at scale, and as such, observability is often not a first priority. We develop our own tools for on-chain and off-chain monitoring, both for short-term metrics (to alert on) and long-term metrics to measure our performance, and to support optimisation decisions.

• Build tools to track and manage our fleet of servers. We work mostly with bare-metal servers across multiple providers. This means that no vendor-specific portal is going to give us a complete overview of our infrastructure, instead we have an in-house tool that integrates with vendor APIs and gives us a central overview.

• Automate machine provisioning. Instead of working with 10+ cloud and bare metal providers’ flavor of installing Ubuntu, we build our own installer that is uniform across our infrastructure.

• Track and automate builds. Each of the 60+ networks we operate regularly releases updates. It would be tedious to manually git pull && make for every release, instead we have automation watching for new releases that automatically builds them and registers them in our package registry.

• Automate updates and failover. When we have a new package, we still need to roll it out to our fleet and restart any nodes, in a controlled manner and without downtime. For validating nodes, we also need to fail over before we restart them, and confirm the new node is healthy. To automate this, we need to have 100% confidence in our tooling, because a mistake here can lead to double-signing, which incurs a financial penalty.

• Automate snapshot creation and storage. Blockchains node software is stateful in nature: the chains are often terabytes in size. While it is possible for new nodes to sync from the p2p network, this can take days to weeks, which means it is not a suitable method when we move workloads between machines. We automate taking snapshots of this data, so we can be more flexible about what runs where, without compromising on security.

Our internal tooling:

Itis written in a mix of Rust, Python, Go, and a bit of TypeScript. We use Postgres as our database of choice. We deploy our code either directly onto Ubuntu hosts, running under systemd or in Docker containers, and we also have a Kubernetes cluster running various stateless applications. Due to the diverse nature of the software we run, we also have to occasionally dive into codebases written in C, C++, OCaml, or TypeScript.

Key Responsibilities

• Design and develop new features. Discuss with internal stakeholders to clarify how ournext 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, helpfellow engineers, and mentor them on a technical level.

• Innovation and continuous improvement. Seek to simplify, optimize, and secure ourstaking services and systems.

• Take part in on-call rotation approximately 2 days per month.You will be responsible for automation that manages our validators and infrastructure, including its uptime and incident response.

What we are looking for:

• 5+ years experience as a Software Engineer.

• Experience with operating and maintaining server-side software in production.

• Deep understanding of at least one compiled statically typed programming language such as Rust, Go, Kotlin, C++, or Haskell.

• Experience with at least one scripting language such as Python.

• Experience using SQL databases, preferably PostgreSQL.

• Strong communication skills and ownership to drive new features independently.

• Interest in blockchain technology, in particular distributed systems and consensus algorithms.

• Affinity with infrastructure and the lower levels of Linux userspace.

• You are able to work in the following time zone: Switzerland ± 6 hours.

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.

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.

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.

• Design, build, and operate our foundational data-heavy services: storage (cloud data warehouse, data lake), orchestration (Airflow), batch processing (Spark, SQL), streaming services (Kafka), query federation and caching, time-series db, graph db, and real-time event aggregation stores.
• Build and maintain data integration & process SDKs for use by internal services and product teams throughout Coinbase.
• Design and build self-service applications to empower our users to manage and troubleshoot their own data pipelines running on our platforms.
• Design and build services for end-to-end data security and data observability: managing access controls across multiple storage and access layers, tracking data quality, cataloging datasets and their lineage, usage auditing.
• Convert functional requests from data analysts, ML, and security & compliance into reusable and scalable patterns; and assemble data microservices into data platforms for critical business verticals and user cohorts.

What we look for in you (ie. job requirements):

• You have at least 5+ years of experience in software engineering.
• You have Strong Python, Go, or Java backend development skills.
• You have general experience working with data systems or data pipelines.
• You are familiar with design patterns such as scale-out, caching, key/value, and columnar.
• You leverage SQL, Python, Airflow, and BI expertise to analyze data for operational insights.

Nice to Have:

• Crypto-forward experience, including familiarity with onchain activity such as interacting with Ethereum addresses, using ENS, and engaging with dApps or blockchain-based services
