  • Architecture & Optimization: Architect blockchain solutions that prioritize scalability, security, and performance while monitoring, troubleshooting, and optimizing production applications.
  • Web3 Integrations: Seamlessly integrate wallets, token standards (ERC-20, ERC-721, ERC-1155), payment systems, and third-party blockchain services.
  • Technical Leadership & Process: Conduct rigorous code reviews, provide mentorship to junior/mid-level developers, and improve development workflows, CI/CD pipelines, and testing frameworks.

Required Skills & Qualifications

  • A minimum of 5+ years of professional software engineering experience, paired with 3+ years of hands-on blockchain development history.
  • Masterful technical command and strong expertise in Solidity and Ethereum smart contract development.
  • Experience building production-grade applications using React , TypeScript , and Node.js .
  • Solid architectural proficiency regarding blockchain architecture, decentralized systems, and modern Web3 libraries (e.g., ethers.js , viem , wagmi ).
  • Strong knowledge of REST APIs, GraphQL, databases, cloud infrastructure, and software design patterns.
  • Excellent problem-solving, communication, and collaboration skills to ensure successful product launches.

Preferred Strategic Indicators (Nice to Have)

  • Prior experience building DeFi , NFT , RWA, or tokenization platforms.
  • Familiarity navigating Layer 2 scaling solutions and cross-chain technologies.
  • Experience conducting or actively supporting smart contract security audits.
  • Knowledge of modern infrastructure automation including AWS, Docker, and Kubernetes.
  • A proven background working in fast-paced startups or open-source contributions within the blockchain ecosystem.

What We Offer

  • Premium Compensation Blueprint: Highly competitive annual salary ranging between $250,000–$300,000 USD, accompanied by performance-based bonuses.
  • Equity & Ownership: Lucrative equity and token incentive opportunities, allowing you to take true ownership of meaningful projects.
  • Remote-First Environment: Enjoy the ultimate flexibility to work from anywhere while collaborating with a world-class, distributed team.
  • Cutting-Edge Innovation: The spectacular professional canvas to work with modern blockchain infrastructure and emerging Web3 technologies alongside talented industry professionals.
