About the Role

We are building a brand new, fully bespoke blockchain from the ground up and need an AI-native, product-minded Full Stack Blockchain Engineer to join the core team. You will be building and shipping blockchain-powered products end-to-end, from the protocol layer and smart contracts through to backend infrastructure and frontend user experience. 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.

Responsibilities

  • Build dApps end-to-end: design and deploy secure, gas-efficient smart contracts; wire up backend infrastructure; deliver clean frontends that hide blockchain complexity
  • Contribute to core chain development: write protocol-level code in Rust, C++ and Python across consensus, execution and networking layers
  • 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
  • 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
  • Represent the team at hackathons and conferences and share your work with the ecosystem

Requirements

  • 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 the ability to deliver complete products, not just isolated code
  • Comfort working at the systems level: Rust and C++ experience is a strong advantage given our bespoke chain focus
  • 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
