Overview We’re looking for an AI-native, product-minded Full Stack Blockchain Engineer to join our core team. You’ll be building and shipping blockchain-powered products end-to-end — from smart contracts and backend infra through to frontend UX. Our work spans gaming, DeFi and other emerging Web3 categories. This is a hands-on role for someone who lives and breathes Web3, ships fast, and embraces AI-powered development workflows to stay ahead. We’re especially excited about builders who are early in their careers but already have real on-chain projects under their belt and a hunger to grow fast. Responsibilities

• Build dApps end-to-end: design and deploy secure, gas-efficient smart contracts; wire up backend infrastructure; and deliver clean frontends that hide blockchain complexity
• Ship products, not just code: collaborate on design, UX, and incentive mechanics, contributing to product decisions as much as technical implementation
• Leverage AI daily: use the latest tools to accelerate development and broaden problem-solving approaches
• Work with blockchain data: build and maintain indexing infrastructure, APIs, and real-time data pipelines
• Experiment and innovate: stay curious with new standards, chains, and techniques — from cross-chain deployments to tokenomics design
• Contribute to open source and community: represent the team at hackathons and conferences, and share your work with the ecosystem

Candidate Profile

• 1–4 years of blockchain/Web3 development with at least one meaningful on-chain deployment (professional, side project, or hackathon)
• Solid foundation in Solidity and TypeScript, with ability to deliver complete products, not just isolated code
• AI-native: daily use of modern coding assistants (Claude, Cursor, Copilot, Windsurf, etc.)
• Product sense: proven ability to think about usability and user experience, not just code correctness
• Previous experience at a blue-chip protocol or well-known project highly valued
• Hackathon experience or open source contributions a strong plus
• Strong English communication skills for async collaboration.
