Senior Smart Contract Auditor

ACTIVE

We are looking for an experienced smart contract auditor to join our core security team. You will lead end-to-end audit engagements, from scoping and threat modeling through manual review, fuzzing, and final report delivery. You will work directly with protocol teams to identify critical vulnerabilities and help remediate them before deployment.

Looking for an audit rather than a role? We provide manual smart contract audits for Solidity and EVM protocols. See our smart contract audit services.

  • Strong written communication for audit reports

Nice to Have

  • Formal verification experience (Certora, Halmos)
  • Experience auditing L2 or cross-chain bridge contracts
  • Published security research or CVEs
  • Competitive audit platform rankings (Code4rena, Sherlock)
