VP, Senior Backend Developer - Blockchain Infrastructure

As VP, Senior Backend Developer for Blockchain Infrastructure at Galaxy Digital, you design and build backend systems powering blockchain infrastructure and staking products. You'll work across Ethereum-based systems, staking infrastructure (native and liquid), and blockchain data systems and APIs, with Liquid Collective as one of several key initiatives. This is a hands-on role with significant ownership where you shape architecture, development practices, and engineering culture.

What you'll do

• 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 standards for API design, testing strategies for distributed systems, reliability and fault tolerance, and security and key management practices
• Operate in a spec-first development environment, translating product and protocol requirements into clear technical specs before building
• Leverage AI-assisted development workflows such as 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, improving systems and workflows
• Champion the thoughtful adoption of AI to improve team performance and business outcomes

What you bring

• 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 such as Flux
• Strong testing practices for complex and stateful systems
• Experience working in remote, asynchronous teams
• High agency and low ego: you own your work end-to-end and hold yourself accountable for quality

Nice to have

• 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 in 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 and flexible working arrangements
• Flexible paid time off
• 3% 401(k) company contribution
