DeFi Domain Expertise: 2+ years of specialized experience in DEX clearing and settlement workflows, including sophisticated Oracle integration.
Multi-Chain Proficiency: Proficient in Rust or Move programming, with the ability to lead contract module development across diverse blockchain ecosystems.
Ecosystem Knowledge: Strong understanding of the architectural paradigms of high-performance chains such as Solana or Sui.
Preferred Qualifications
Experience developing advanced vault standards (e.g., ERC-4626, ERC-7540, or ERC-7575) and complex accounting logic.
Familiarity with advanced security methodologies, including Fuzzing or Formal Verification.
Proven track record of successful smart contract audits or hands-on experience in incident response and protocol hardening.
