£90,000–£150,000
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
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 staking and blockchain infrastructure projects across Galaxy
Define and uphold engineering standards
Set and maintain the bar on API design, testing strategies for distributed systems, reliability and fault tolerance, and security and key management practices
Operate in a spec‑first development environment — translate product and protocol requirements into clear technical specs before building
Leverage AI‑assisted development workflows (e.g. Claude Code) and work with emerging paradigms like MCP (Model Context Protocol) and agent‑based tooling
Collaborate and contribute to engineering culture
Work cross‑functionally with protocol, product, and infrastructure teams
Mentor engineers through code review, design feedback, and raising the overall quality of what the team ships
Contribute to how the team evolves its practices — not just executing within the current system, but improving it
Embrace and champion the thoughtful adoption of AI to improve team performance and business outcomes
Leverage AI tools (e.g., generative AI, automation platforms, data copilots) to improve productivity, decision‑making, and output quality in your day‑to‑day work

High agency, low ego — you own your work end‑to‑end and hold yourself accountable for quality
Experience working in remote, asynchronous teams
Strong experience building backend systems in Golang
Deep understanding of distributed systems.
Experience working with blockchain systems, preferably Ethereum — including familiarity with execution vs consensus layers, node operation, and data flow
Experience with cloud‑native infrastructure: AWS, Kubernetes, Helm, GitOps (e.g. Flux)
Hands‑on experience with Ethereum nodes (execution and/or consensus clients) or validator and staking infrastructure
Experience building blockchain indexers, data pipelines, dApps, or smart contracts (Solidity)
Understanding of proof‑of‑stake mechanisms
Familiarity with AI‑assisted development workflows: spec‑driven development, code generation tools, MCP, or agent‑based paradigms
