AG - Staff-Level Fullstack Blockchain Engineer B. - Job3690

Summary

An innovative company in the blockchain space is looking for a Staff-Level Full-Stack Blockchain Engineer to develop the next generation of on-chain governance applications. The role involves designing, scaling, and improving the user experience in key products, working closely with engineering, design, and product teams.

Responsibilities

• Develop and enhance on-chain governance applications, ensuring scalability and improved user experience.
• Build and maintain full-stack applications using Next.js and Node.js, optimized for scalability and maintainability
• Design intuitive, crypto-native UI/UX that interacts with wallets, proposals, voting systems, and token-gated content
• Develop typed backend APIs (REST/GraphQL) to serve blockchain data to the frontend in real-time
• Integrate with EVM smart contracts
• Write indexing pipelines to sync and persist on-chain events into PostgreSQL
• Design and manage relational database schemas to handle proposals, votes, user actions, and transaction metadata
• Collaborate with product, design, and smart contract engineers to build aligned systems
• Take initiative on architecture decisions and propose improvements across backend and frontend codebases

Requirements

Must-Have Skills

• 5+ years of experience in Full-Stack web development with TypeScript and modern frameworks like Next.js
• Solid understanding of Frontend and Backend fundamentals (React/Next.js and TypeScript), server-side rendering, caching strategies, and dynamic routing
• Proficiency in building secure, scalable backend services using Node.js and PostgreSQL
• Experience designing relational database schemas and writing optimized queries for performance
• Hands-on experience interacting with Solidity/EVM smart contracts
• Familiarity with on-chain/off-chain data sync, contract event indexing, and blockchain architecture
• Comfort working in crypto-native environments—you understand governance cycles, DAO tooling, wallet UX, and token gating
• Ability to speak fluently across the stack—from UI state to backend infra to smart contract logic
• Strong understanding of Next.js internals
• Self-driven and comfortable making product and architectural decisions without constant direction

Nice-to-Have Skills

• Familiarity with Foundry, Hardhat, or similar Solidity dev frameworks
• Contributions to DevOps tooling around smart contract deployment (e.g., using Foundry)
• Experience building indexers or working with data sync tools like The Graph
• Knowledge of Layer 2 solutions (Optimism, Arbitrum, zk-rollups) and how they impact app architecture
• Comfort with advanced Web3 concepts like gas optimization, multisigs, and upgradeable contracts
• Experience improving contributor tools, dashboards, or governance UX in crypto products
