Job Description

Senior Web3 Software Engineer

MLabs

• Dapp Development: Design, build, and maintain modern, responsive frontend applications integrated with blockchain protocols for core DeFi products and exchanges. • Protocol Integration: Implement integrations with blockchain infrastructure (e.g., EVM chains, custom VMs), wallet extensions (MetaMask, Phantom, WalletConnect), and on-chain data sources such as subgraphs and indexers. • Security & User Flow: Execute secure user flows for transactions, multi-sig approvals, cross-chain bridging, and account abstraction. • Infrastructure Collaboration: Contribute to API design (REST/GraphQL), RPC optimization, and indexer queries to ensure high-performance, real-time data delivery. • Technical Leadership: Establish frontend architecture, design systems, and Web3 best practices, including gas optimization, reentrancy guards, and accessibility. • Mentorship & Code Quality: Perform rigorous code reviews (including Solidity/Sway), mentor engineering staff, and drive strategic decisions regarding stack interoperability and scalability. • UX Optimization: Translate complex DeFi requirements, such as MEV protection and oracle feeds, into intuitive UI/UX for professional trading interfaces. • Roadmap Strategy: Proactively identify technical debt, propose infrastructure upgrades, and technically shape the product roadmap.

Job Requirements

  • Professional Experience: 5+ years of software engineering experience, with at least 2 years in a senior or lead capacity specifically building Web3 or blockchain applications.
  • Frontend Expertise: Deep proficiency in modern frameworks (React, Next.js, or Vue) using TypeScript/JavaScript, alongside Web3 libraries (ethers.js, viem, wagmi).
  • Dapp Specialization: Strong experience developing complex, data-intensive dapps that handle real-time streams, such as order books or AMM curves.
  • On-Chain Interaction: Proven ability to manage browser wallet connections and execute on-chain interactions via providers (Alchemy, Infura) and libraries for reads, writes, and calls.
  • Security Literacy: A solid grasp of Web3 security principles, including private key management, blind signing risks, and mitigation of sandwich attacks or phishing.
  • Full-Stack Awareness: Experience with Node services (Express, FastAPI), off-chain indexers (The Graph), and event listening mechanisms.
  • Data Management: Proficiency in REST/GraphQL, data fetching (SWR, TanStack Query), and state management (Zustand, Redux) within volatile market contexts.

Benefits

  • High-Impact Ownership: The opportunity to lead the development of critical dapps at the intersection of Web2 and Web3.
  • Full-System Autonomy: Freedom to architect complete systems, spanning from UI to smart contracts and off-chain bots.
  • Expert Collaboration: Work alongside a globally dispersed team of deep blockchain experts focused on network and DeFi innovation.
  • Innovative Environment: Access to cutting-edge tools and a mission-driven culture dedicated to shaping the future of decentralized finance.
