📋 Description

• 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. • 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. • 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.

🎯 Requirements

• 7+ years of professional software engineering experience. • 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). • Strong testing practices for complex and stateful systems. • Experience working in remote, asynchronous teams. • High agency, low ego — you own your work end-to-end and hold yourself accountable for quality.
