📋 Description

• Design, implement, and test Solidity smart contracts for data tokenization, licensing, and pricing workflows. • Develop robust on-chain data structures to represent enterprise datasets, metadata, and access conditions. • Architect marketplace and exchange primitives including order books, escrow, dispute resolution, and royalties. • Integrate pricing logic grounded in financial derivatives (e.g., options pricing, bonding curves, auction models). • Optimize gas efficiency and ensure upgradability where needed using proxies or modular contracts. • Collaborate with auditors and internal security teams to harden contracts against vulnerabilities. • Work cross-functionally with product and protocol teams to define new features and mechanisms.

🎯 Requirements

• 3+ years of Solidity development experience with a strong portfolio of deployed smart contracts. • Proven understanding of EVM architecture, smart contract security, and gas optimization. • Experience building or contributing to Web3 exchanges, NFT marketplaces, or DeFi protocols. • Deep familiarity with data modeling, complex storage patterns, and Solidity-specific design patterns. • Knowledge of token standards (ERC20, ERC721, ERC1155, ERC4626) and upgradeable contract frameworks. • Exposure to pricing mechanisms, such as dynamic pricing curves, auctions, or option-like instruments. • Proficient in development tools (Hardhat, Foundry, Tenderly, etc.) and testing frameworks (Chai, Waffle). • Comfortable with Git-based workflows and agile engineering processes.
