• Design, build, and maintain modern, responsive frontend applications integrated with blockchain protocols for core DeFi products like exchanges. • Integrate with blockchain infrastructure (e.g., EVM chains, Fuel VM), wallet extensions (MetaMask, Phantom, WalletConnect), and on-chain data sources (e.g., subgraphs, indexers). • Implement secure user flows for transactions, multi-sig approvals, cross-chain bridging, and account abstraction. • Collaborate on API design (REST/GraphQL), RPC optimization, and indexer queries for real-time data. • Establish frontend architecture, design systems, and Web3 best practices (testing with Hardhat/Foundry, gas optimization, reentrancy guards, accessibility). • Review code (including Solidity/Sway), mentor engineers, and drive technical decisions on stack interoperability and scalability. • Translate complex DeFi requirements (e.g., MEV protection, oracle feeds) into intuitive UI/UX for trading interfaces. • Proactively identify technical debt in smart contracts or frontend, propose upgrades (e.g., account abstraction), and shape the product roadmap technically.

• Serve as technical lead for cross-cutting initiatives like the Reporting Engine rearchitecture, performance scaling, and AI reporting integration. • Collaborate with engineers, product managers, and designers to define and deliver impactful customer-facing features. • Drive architectural decisions that ensure our reporting systems are reliable, performant, and extensible. • Help establish engineering best practices in data modeling, distributed systems, and query optimization. • Lead design reviews, guide implementation, and mentor staff- and senior-level engineers. • Dive deep into technical problems while maintaining a strategic, long-term perspective. • Represent the Reporting team in cross-functional planning efforts and engineering leadership forums. • Think creatively, own problems, seek solutions, and communicate clearly along the way. • Contribute to a collaborative environment rooted in learning, teaching, and transparency
