## About the Role

Do you have experience in Usability?, Systems: Rust | C++ | CUDA (GPU acceleration)

Scripting / Automation: Python | Shell

All protocol components, consensus mechanisms, execution environments and networking are written in-house. Familiarity with low-level systems programming, memory safety and performance optimisation is essential.

Smart Contracts

Languages: Solidity (EVM), * 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, * Growth mindset
 * Curiosity, adaptability and eagerness to learn
 * Strong in code, sharp on product
 * A track record of building: shipped protocols, hackathon projects or ambitious side hustles

## Description

* 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
