Who You Are:
You ll design and build backend systems powering blockchain infrastructure and staking products across Galaxy — spanning Ethereum-based systems, staking infrastructure (native and liquid), and blockchain data systems and APIs. Liquid Collective is one of several key initiatives you ll contribute to.
This is a hands-on role with significant ownership and influence. You ll play a key part in shaping architecture, development practices, and engineering culture — not just building features, but raising the bar on how the team works. You ll own systems end-to-end, from architecture through to observability, and you ll operate in a spec-first development environment that increasingly leverages AI-assisted workflows.
Typical time allocation: roughly 60% building systems and features, 20% code review and mentorship, 20% design, architecture, and product collaboration.
What You’ll Do:
- Build and own backend systems
- Design and build APIs, services, Ethereum data pipelines and indexers, staking and validator infrastructure integrations, and monitoring and operational tooling.
- Own system design end-to-end: architecture, implementation, testing, deployment, and observability.
- Work across the Ethereum stack, integrating with both execution layer and consensus layer clients.
- Contribute to Liquid Collective alongside other
