About the Role

We are looking for a highly skilled Smart Contract Auditor to join our security team. In this role, you will be responsible for reviewing, analyzing, and securing smart contracts across multiple blockchain ecosystems, primarily EVM-compatible networks.

You will identify vulnerabilities, assess protocol risks, and provide actionable recommendations to ensure the highest level of security and reliability for decentralized applications, DeFi protocols, payment systems, and digital asset infrastructure.

The ideal candidate has strong experience in Solidity development, smart contract security, and blockchain architecture, combined with a deep understanding of common attack vectors and emerging security threats.

Key Responsibilities

  • Perform comprehensive security reviews of smart contracts and blockchain protocols.
  • Identify vulnerabilities, logic flaws, economic exploits, and protocol design weaknesses.
  • Conduct manual code reviews and security assessments.
  • Develop proof-of-concept exploits to validate findings when necessary.
  • Review protocol architecture, upgrade mechanisms, access controls, and governance systems.
  • Analyze interactions with external protocols, bridges, oracles, and third-party dependencies.
  • Prepare professional audit reports with clear risk assessments and remediation recommendations.
  • Collaborate closely with engineering teams during remediation and re-audit processes.
  • Contribute to internal security tools, testing frameworks, and auditing methodologies.
  • Stay informed about the latest security incidents, exploits, and emerging attack vectors in the blockchain ecosystem.

Requirements

Must Have

  • 3+ years of experience in blockchain development or smart contract security.
  • Strong proficiency in Solidity and EVM internals.
  • Deep understanding of smart contract vulnerabilities, including:
    • Reentrancy
    • Access control issues
    • Integer overflows and underflows
    • Oracle manipulation
    • Flash loan attacks
    • Signature validation issues
    • Front-running and MEV risks
    • Economic and protocol-level exploits
  • Experience auditing DeFi protocols and token standards.
  • Strong understanding of Ethereum architecture and transaction lifecycle.
  • Experience using security tools such as Slither, Foundry, Hardhat, Echidna, Mythril, or similar.
  • Ability to write and maintain comprehensive test suites.
  • Excellent analytical and problem-solving skills.

Nice to Have

  • Public audit portfolio or disclosed security research.
  • Experience participating in bug bounty programs.
  • Familiarity with Layer 2 ecosystems and cross-chain protocols.
  • Knowledge of cryptographic concepts including MPC, threshold signatures, and zero-knowledge technologies.
  • Experience auditing protocols involving staking, lending, AMMs, derivatives, or stablecoins.
  • Contributions to open-source blockchain projects.

What We Offer

  • Fully remote work environment.
  • Flexible working hours.
  • Opportunity to work on cutting-edge blockchain infrastructure and Web3 products.
  • Collaboration with experienced blockchain engineers and security researchers.
  • Competitive compensation package.
  • Continuous professional development and learning opportunities.
  • Supportive team culture focused on security, innovation, and technical excellence.

Why Join Us?

Security is one of the most critical pillars of the Web3 ecosystem. As a Smart Contract Auditor, your work will directly protect user funds, strengthen decentralized infrastructure, and help build more secure blockchain applications for the future.
