Senior Backend Developer

You will design and build backend systems powering blockchain infrastructure and staking products across Galaxy including Ethereum based systems. You will own system design end to end from architecture through to observability. You will work across the Ethereum stack, integrating with both execution layer and consensus layer clients. You will contribute to Liquid Collective alongside other staking and blockchain infrastructure projects across Galaxy. You will set engineering standards for API design testing strategies for distributed systems reliability fault tolerance and security and key management practices. You will operate in a spec first development environment translate product and protocol requirements into clear technical specs before building. You will leverage AI assisted development workflows and work with emerging paradigms like MCP and agent based tooling. You will collaborate cross functionally with protocol product and infrastructure teams. You will mentor engineers through code review design feedback and raising the overall quality of what the team ships. You will contribute to how the team evolves its practices not just executing within the current system but improving it. You will embrace and champion the thoughtful adoption of AI to improve team performance and business outcomes. You will leverage AI tools to improve productivity decision making and output quality in your day to day work.
