    • Ensure the long-term reliability and security of the protocol by defining testing standards, conducting internal audits, and designing for upgradability.
    • Solve complex distributed system problems, prioritizing performance and economic efficiency (gas/resource optimization) across the entire stack.
    • Act as a technical leader and mentor, elevating the team’s standards through code reviews, architectural RFCs, and knowledge sharing.

     

    Required Skills

    • Rust Proficiency: Solid professional experience with Rust. You understand memory safety, concurrency, and how to write clean, idiomatic code.
    • Engineering Fundamentals: Deep understanding of computer science principles, data structures, algorithms, and distributed systems architecture.
    • Testing Culture: A strong habit of writing comprehensive unit and integration tests. You don't just write code; you prove it works.
    • Intellectual Flexibility: A demonstrated ability (and willingness) to dive into new documentation, learn new protocols (like Casper/Wasm), and adapt to changing technical requirements.
    • English Proficiency: Upper-Intermediate (B2) or higher, capable of discussing abstract architectural concepts clearly.

     

    Preferred Skills

    • Blockchain Experience: Experience with smart contract development on any chain (Casper, Solana, NEAR, Ethereum, Polkadot).
    • Wasm & Compilers: Knowledge of WebAssembly or low-level compilation targets.
