Web3 Developer - Blockchain & Decentralized Applications (Remote)
Job Overview
We are looking for a skilled Web3 Developer with expertise in blockchain development, decentralized applications (dApps), and smart contract engineering. You will be responsible for designing and implementing a hybrid Web3 architecture that integrates on-chain smart contracts with off-chain middleware for a decentralized logistics and marketplace system.
This project leverages cutting-edge technologies such as Ethereum, Polygon, IPFS, Chainlink, and decentralized identity solutions, requiring experience in smart contract development, blockchain indexing, and Web3 integrations.
Key Responsibilities
• Develop smart contracts on Ethereum / Polygon / Optimism, ensuring security, efficiency, and scalability.
• Implement decentralized identity (DID) and verifiable credentials using tools like Spruce ID or Ceramic.
• Design and integrate oracles and cross-chain bridges for real-world data synchronization (Chainlink, The Graph).
• Develop and maintain Web3 APIs (GraphQL, The Graph, REST) to enable seamless blockchain interaction.
• Work with IPFS / Arweave for decentralized storage solutions.
• Optimize gas fees and Layer2 rollup transactions for efficient blockchain interactions.
• Collaborate with frontend developers to integrate Web3 functionalities into a React/Vue.js UI.
• Implement decentralized governance mechanisms (Snapshot, Aragon) for community participation.
• Ensure smart contract audits, formal verification, and security best practices.
• Integrate WalletConnect, MetaMask, and other Web3 authentication tools for seamless user access.
Skills & Qualifications
Must-Have:
• 3+ years experience in Web3, blockchain, and smart contract development.
• Proficiency in Solidity, Hardhat, Foundry, and smart contract security.
• Experience with Ethereum, Polygon, Optimism, or other EVM-compatible chains.
• Familiarity with decentralized storage (IPFS, Arweave) and indexing (The Graph).
• Strong understanding of oracles (Chainlink), blockchain bridges, and interoperability.
• Ability to optimize smart contracts for low gas fees and high performance.
• Experience with GraphQL APIs, Node.js, and Web3.js / ethers.js.
• Knowledge of decentralized identity (DID) and verifiable credentials.
• Experience integrating decentralized governance (Snapshot, Aragon).
• Security-first mindset with experience in smart contract audits.
Nice-to-have:
• Familiarity with Zero-Knowledge Proofs.
• Experience in DAOs and community-driven governance models.
• Previous work with Web2-to-Web3 integrations.
Tools & Technologies
• Smart Contracts
• Blockchain Networks
• Oracles & Indexing
• Identity & Authentication
• Governance & DAO Tools
• APIs & Middleware
• Frontend
• Cloud Solutions
How to Apply:
Interested candidates should submit their resume and a cover letter detailing their relevant experience and why they are a good fit for this position to [insert application email or link].
