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 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.
What We're Looking For:
- 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.
Bonus Points:
- Hands-on experience with Ethereum nodes (execution and/or consensus clients) or validator and staking infrastructure.
- Understanding of proof-of-stake mechanisms.
- Experience building blockchain indexers, data pipelines, dApps, or smart contracts (Solidity).
- Familiarity with AI-assisted development workflows: spec-driven development, code generation tools, MCP, or agent-based paradigms.
- Contributions to open-source projects.
- Experience with Rust.
What We Offer:
- Competitive base salary and discretionary bonus
- Hybrid/Flexible Working Arrangements
- Flexible Time Off (paid)
- 3% 401(k) company contribution
- Company-paid health and protective benefits for employees, partners, and other dependents
