## TL;DR
- **Role:** Backend Integrations Engineer at Yield.xyz
- **Level:** Junior
- **Comp:** Not listed
- **Setup:** Remote · Remote (US)
- **Type:** Full-time

## You Might Be a Fit If...
- Mentor and collaborate with other engineers across the organization, sharing knowledge on backend architecture and Web3 primitives
- Own shipping with minimal guidance from technical design and implementation through to deployment, monitoring, and iteration based on real-world performance What We re Looking For Must-Haves• 5+ years shipping production-grade backend systems at scale
- Strong TypeScript and Node.js proficiency (NestJS experience is a plus)
- Deep expertise with PostgreSQL and hands-on production experience with Redis (or similar in-memory data stores), including designing efficient schemas, writing optimized queries, handling complex data relationships, and implementing caching, sessions, and real-time data workflows.
- Solid understanding of cloud infrastructure, particularly AWS, and how to build reliable, scalable systems
- Excellent communication skills, especially async and written, to collaborate effectively with distributed teams Strong Advantages
- **Web3 familiarity:** understanding of RPCs, blockchain signing mechanisms, multi-chain interactions, and Solidity smart contracts
- Experience building scalable data pipelines and indexing systems (The Graph, Subgraphs, custom blockchain indexers, etc.)
- Blockchain infrastructure experience: you ve built systems that interact with blockchain nodes or smart contracts
- Deep knowledge of staking, DeFi protocols, validator architecture, or yield mechanisms
- Experience at high-growth startups in fast-moving, ambiguous environments where you ve had to wear multiple hats

## What You'll Actually Do
- Design and build high-throughput, low-latency backend services in TypeScript/Node.js, with deep attention to API design, schema stability, and versioning
- Architect performant PostgreSQL schemas and optimize complex queries for production workloads; leverage Redis for caching and real-time data access
- Build robust data pipelines that ingest, process, and normalize blockchain protocol data in real-time at scale
- Integrate emerging yield sources (staking, restaking, DeFi protocols) into the Yield.xyz engine including smart contract interaction, transaction signing, and multi-chain coordination
- Develop and maintain external-facing APIs that power integrations for major Web3 wallets and fintech platforms
- Conduct technical R&D on emerging protocols, validator architectures, and Web3 infrastructure; propose integration strategies and contribute to planning
- Operate services on AWS in close partnership with DevOps engineers to ensure reliability, performance, and security at scale
- Participate in a rotating on-call schedule to triage and respond to site-wide incidents, ensuring uptime and stability across our APIs, integrations, and data pipelines.
- **API design expertise:** you understand schema versioning, backward compatibility, rate limiting, and building APIs that scale
- Senior-level ownership mentality: you can design, build, test, and ship features end-to-end with minimal guidance
- Self-starter energy: you love building code, solving complex problems, and taking initiative
- Attention to detail in system design, security, and performance; you think about edge cases and failure modes
- Open-source contributions, particularly in Web3 or data infrastructure projects
- Demonstrated curiosity about emerging Web3 technologies and a genuine interest in the space Why Join Yield.xyz?
- Work on critical infrastructure powering the next generation of decentralized finance and Web3 wallets
- **High autonomy and ownership:** shape product direction, architect systems, and have real influence on technical decisions
- Collaborate with exceptional engineers backed by top-tier investors and advisors
- **Build for industry leaders:** your work directly powers Ledger, Deblock, and dozens of leading fintech and crypto platforms globally
- Fully distributed team across multiple continents. Work from anywhere within American timezones.
- Competitive salary and equity package with plans to transition to full-time employment
- **Learn at the frontier:** dive deep into Web3 infrastructure, yield mechanisms, and decentralized finance at a critical moment in the industry
