About the company
Our client is on a mission to redefine finance by powering stablecoins, facilitating digital
asset tokenization, and building decentralized infrastructure across chains. We believe
in breaking the chains of traditional finance and enabling freedom, scale, and
transparency.
Role Overview
As a Blockchain Developer, you will design, develop, test, and deploy smart contracts
and blockchain-based systems that form the backbone of our products and services
(e.g. USD₮, tokenization platforms, bridging, etc.). You will work closely with cross-
functional teams (product, security, DevOps, compliance) to deliver robust and secure blockchain solutions.
Key Responsibilities
• Design, write, audit, and maintain smart contracts (e.g. in Solidity, Vyper, Rust, etc.)
• Integrate smart contracts with back-end systems (APIs, webservices)
• Implement token standards (ERC-20, ERC-721, ERC-1155, or equivalents on
other chains)
• Develop and maintain blockchain infrastructure components, such as nodes,
relayers, indexers
• Collaborate with front-end teams to integrate wallets, DApps, UI interactions
• Participate in security reviews, write tests, and adhere to best practices (unit
tests, integration tests, fuzzing)
• Monitor and optimize gas usage, performance, and scalability
• Stay updated with new blockchain protocols, upgrades, and ecosystem
developments
• Troubleshoot, debug, and upgrade live smart contract systems when necessary
Qualifications / Requirements
• Bachelor’s or Master’s degree in Computer Science, Software Engineering, or
equivalent
• 3+ years of experience in blockchain / smart contract development
• Proficiency in one or more smart contract languages, e.g. Solidity, Rust, Vyper,
Move, etc.
• Familiarity with Ethereum, EVM-compatible chains, or alternative chains (e.g.
Solana, Polkadot, Avalanche)
• Understanding of cryptography fundamentals (hashing, signatures, Merkle trees)
• Experience with testing frameworks (e.g. Hardhat, Tru]le, Foundry)
• Familiarity with web3 libraries (ethers.js, web3.js), wallet integrations (MetaMask,
WalletConnect)
• Knowledge of tooling: Remix, Tru]le, Hardhat, Ganache, Geth, etc.
• Strong software engineering skills: version control (Git), CI/CD, code reviews
• Attention to security, gas optimization, and performance
• Excellent problem-solving, communication, and collaboration skills
• Bonus: experience with cross-chain, bridges, layer 2, rollups
