Web3 Tech Lead - Fully EU Remote

Barcelona $6,000 – $8,000 USD/month Contract

12 month contract

Start date 1st June.


We’re searching 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.



Job responsibilities include:

  • 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.


What you bring to the table:

  • 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.
  • Prior technical lead role
  • Familiarity with Vercel/AWS deployments and CI/CD pipelines
  • TypeScript, NextJS, and React Knowledge
