Web3 Technical Team Lead

Overview We’re on the hunt for a Web3 Team Lead who doesn’t just ship features—they steer squads, architect clean integrations, and push high-quality Web3 products over the finish line. At Linum Labs, we’re building more than just smart contracts. We’re launching DeFi platforms, orchestrating full-stack blockchain apps, and experimenting at the bleeding edge in our Venture Studio. From production-grade audits to zero-to-one MVPs, we’re scaling fast—and we need a technical leader who can bring clarity to chaos and lead teams that deliver. This isn’t a “just keep the lights on” role. You’ll be deep in the details of frontend/backend/contract coordination, while keeping the bird’s eye view to drive delivery. Who we are looking for We’re looking for a Web3 Technical Team Lead who can coordinate a cross-functional Web3 team through delivery — ensuring clarity across frontend, backend, indexing, and contract integration workflows. While hands-on smart contract coding is not required, you should be deeply familiar with how DeFi systems work, how to interact with smart contracts, and how to guide a team in integrating them safely and effectively. Key Responsibilities Technical Coordination: Ensure seamless communication and technical alignment between frontend, backend, QA, and smart contract teams. Architecture Stewardship: Own the integration architecture — how contracts, The Graph, backend workers, and the web app interconnect. Sprint Leadership: Translate high-level requirements into actionable engineering tasks and support the PM with sprint planning and team coordination. Code Review (Non-Solidity): Review and guide frontend, API/backend, and indexing work — ensuring implementation meets the spec and integrates cleanly with contracts. Testing & Delivery: Coordinate QA across the stack, assist in defining test plans for DApp-contract interactions, and support final release testing and walkthroughs. Must-Haves 5+ years of engineering experience, with recent focus on Web3 or DeFi application delivery. Proven experience integrating smart contracts into frontend or backend systems (e.g. via ethers.js, web3.js, or API wrappers). Familiarity with The Graph, including designing subgraph schemas and using GraphQL for indexed on-chain data. Experience working with product designers, PMs, and QA to coordinate cross-functional MVP delivery.
