Join Galaxy as a Senior Backend Developer to design and build backend systems for blockchain infrastructure and staking products. Competitive salary, remote work, and a culture of innovation await you.
Galaxy is a global leader in digital assets and data center infrastructure, delivering solutions that accelerate progress in finance and artificial intelligence. We believe that blockchain and digital asset innovation will transform how value moves through the world – and we’re building the products and services to make that future a reality.
Our institutional digital assets platform spans trading, investment banking, asset management, staking, self-custody, and tokenization technology. We also invest in and operate cutting-edge data center infrastructure to power AI and high-performance computing, addressing the growing demand for scalable energy and compute in the U.S.
We work at the intersection of finance and technology, helping institutions, startups, and developers navigate a digitally native economy. Led by CEO and Founder Michael Novogratz, our team blends deep crypto expertise with institutional experience and a shared commitment to shaping the future of Web3 and AI.
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
- Generous paid Parental Leave
- Competitive family planning benefits for US employees
- Opportunities to learn about the Crypto industry
- Smart, entrepreneurial, and fun colleagues
- Free daily snacks and weekly breakfasts/lunches
- Employee Resource Groups
- Free coaching and counseling sessions through Headspace.
