Backend Engineer

About This Role

This role involves expanding the backend engineering team to support the core technical foundation of Yield.xyz, focusing on architecting and shipping robust data pipelines, protocol integrations, and high-throughput APIs for decentralized finance. The engineer will have meaningful ownership, directly influencing the technical roadmap and shaping future developments.

Responsibilities

• Design and build high-throughput, low-latency backend services in TypeScript/Node.js with attention to API design, schema stability, and versioning.
• Architect performant PostgreSQL schemas and optimize complex queries; leverage Redis for caching and real-time data access.
• Build robust data pipelines to ingest, process, and normalize blockchain protocol data in real-time at scale.
• Integrate emerging yield sources (staking, restaking, DeFi protocols) including smart contract interaction, transaction signing, and multi-chain coordination.
• Develop and maintain external-facing APIs for major Web3 wallets and fintech platforms.
• Conduct technical R&D on emerging protocols, validator architectures, and Web3 infrastructure.
• Operate services on AWS to ensure reliability, performance, and security at scale.
• Participate in a rotating on-call schedule to triage and respond to site-wide incidents.
• Mentor and collaborate with other engineers across the organization on backend architecture and Web3 primitives.
• Own shipping features end-to-end with minimal guidance, from technical design to deployment, monitoring, and iteration.

Requirements

• 5+ years shipping production-grade backend systems at scale
• Strong TypeScript and Node.js proficiency
• Deep expertise with PostgreSQL and hands-on production experience with Redis
• Solid understanding of cloud infrastructure, particularly AWS
• API design expertise (schema versioning, backward compatibility, rate limiting, scalability)
• Senior-level ownership mentality (design, build, test, ship features end-to-end with minimal guidance)
• Self-starter energy and attention to detail
• Excellent communication skills (async and written) for distributed teams

Qualifications

• 5+ years shipping production-grade backend systems at scale

Nice to Have

• NestJS experience
• Web3 familiarity (RPCs, blockchain signing, multi-chain interactions, Solidity smart contracts)
• Experience building scalable data pipelines and indexing systems (The Graph, Subgraphs, custom blockchain indexers)
• Blockchain infrastructure experience (interacting with blockchain nodes or smart contracts)
• Deep knowledge of staking, DeFi protocols, validator architecture, or yield mechanisms
• Open-source contributions, particularly in Web3 or data infrastructure projects
• Experience at high-growth startups
• Demonstrated curiosity about emerging Web3 technologies
