We are looking for a technically strong and product-oriented Blockchain Developer who brings a full-stack engineering mindset and deep understanding of decentralized technologies, especially around token standards (ERC-20, ERC-721, ERC-1400, etc.), multi-chain deployments, and real-world asset (RWA) tokenization in the financial services domain. You will play a critical role in building and scaling our blockchain infrastructure and applications powering structured finance, digital custody, and asset tokenization Responsibilities : - Design and develop smart contracts and tokenization logic using Ethereum and/or other blockchain networks (Polygon, Avalanche, Solana, Hyperledger, etc.) - Work with multiple token standards (ERC-20, ERC-721, ERC-1155, ERC-4626, ERC-3643/ERC-1400, SPL tokens, etc.) and choose the right standard per use case - Build and integrate wallets, custody mechanisms, and token lifecycle operations (mint, burn, transfer, freeze, etc.) - Architect scalable full-stack blockchain applications using modern web frameworks (e.g., React, Next.js, Node.js) and backend stacks (Express, NestJS, etc.) - Collaborate with cross-functional teams to translate financial workflows into blockchain-based protocols - Address challenges related to key management, access control, compliance, and interoperability - Write clean, testable, and auditable code; conduct code reviews and contribute to best practices - Stay updated on evolving blockchain technologies, DeFi primitives, and tokenization Qualifications : - 3 to 7 years of software development experience with at least 2+ years in blockchain development - Strong proficiency in Solidity (and optionally Rust or Golang depending on chains used) - Hands-on experience with at least one public or permissioned blockchain, and exposure to others - Knowledge of token standards (ERC-20, ERC-721, ERC-1155, ERC-1400/3643, etc.) - Experience working on wallets, custody solutions, asset registries, or compliance layers - Familiarity with RWA tokenization, structured finance, or financial service applications on-chain - Solid experience in full-stack web development using JavaScript/TypeScript, React, Node.js - Experience with Web3 libraries (ethers.js, web3.js), Truffle/Hardhat, The Graph, IPFS - Good understanding of security practices for smart contract to Have : - Experience with multi-signature wallets, MPC, or HSM integrations - Exposure to regulated environments (e.g., working with regulated token offerings, custody providers, or compliance tech) - Familiarity with custodial and non-custodial wallet frameworks - Understanding of tokenized fund structures or lending We Offer : - Opportunity to build infrastructure for the future of financial markets - Work with a team that understands both finance and blockchain deeply - Competitive compensation and ESOPs (ref:hirist.tech)
