Job Description: Full Stack Solidity Developer

Job Summary

Build the future of Web3! Design secure smart contracts & intuitive dApps. Take full control from Solidity to React. Let’s innovate on Mainnet!

We are seeking a visionary Full Stack Solidity Developer to design, develop, and deploy decentralized applications (dApps). You will bridge the gap between secure on-chain smart contracts and intuitive off-chain user interfaces. Your primary focus will be ensuring code integrity on-chain while providing a seamless user experience.

Key Responsibilities

• Smart Contract Development: Design, write, and test efficient and secure smart contracts using Solidity (EVM-based).
• Frontend Integration: Build responsive web interfaces that interact with the blockchain using libraries such as Ethers.js or Web3.js.
• Security & Optimization: Conduct internal audits, optimize gas usage, and ensure contracts are protected against common vulnerabilities (e.g., reentrancy attacks).
• Backend & Indexing: Develop supporting APIs and implement indexing solutions like The Graph to fetch blockchain data efficiently.
• Deployment & DevOps: Manage deployments to Testnets (Sepolia/Goerli) and Mainnet, and maintain node infrastructure as needed.
• Collaboration: Work closely with UI/UX designers to ensure smooth wallet workflows (MetaMask, WalletConnect) for users.

Technical Qualifications (Tech Stack)

1. Blockchain & Smart Contracts

• Programming Language: Solidity (Advanced).
• Development Frameworks: Hardhat, Foundry, or Truffle.
• Deep understanding of token standards: ERC-20, ERC-721 (NFT), ERC-1155.
• Experience with Proxy Contracts (Upgradable Contracts) and OpenZeppelin libraries.

2. Frontend & Web3

• Frameworks: React.js or Next.js.
• State Management: Redux, Context API, or Zustand.
• Web3 Libraries: Ethers.js, Web3.js, or Wagmi/Viem.

3. Backend & Database

• Runtime: Node.js or Go.
• Databases: PostgreSQL, MongoDB, or Redis for off-chain data caching.
• Indexing: GraphQL and The Graph Protocol.

Preferred Qualifications (Nice to Have)

• Understanding of DeFi protocols (Lending, AMM, Staking).
• Experience with Layer 2 solutions (Arbitrum, Optimism, Polygon).
• Foundational knowledge of cybersecurity and cryptography.
• Active contributions to Open-Source Web3 projects (GitHub/Portfolio).
