Security Engineer

Skills

About the Role

You will audit Move modules, protocol code, and consensus and networking layers for vulnerabilities. You will build security tooling, lead formal verification and threat-modeling work, manage bug bounty triage, coordinate incident response, and work with engineers and external security researchers to improve protocol security.

Requirements

• Demonstrated record of finding real vulnerabilities through audit reports, CVEs, bug bounties, security research, or CTF results
• Code-level security skills for Move modules or Solidity codebases
• Understanding of at least one smart contract VM: Move, EVM, or SVM
• Ability to write Move, Solidity, Rust, or Python for security tooling
• Knowledge of smart contract vulnerabilities, consensus security, BFT failure modes, cryptographic primitives, bridge security, and cross-chain security
• Experience with adversarial security analysis and security tooling automation

Responsibilities

• Audit Move modules, Solidity and Rust protocol code, and consensus and networking layers for vulnerabilities
• Design and build fuzzers, invariant tests, static analyzers, formal specifications, and runtime monitoring
• Drive formal verification using the Move Prover and write specifications for critical modules
• Threat-model consensus, execution, data availability, bridges, RPC, and validator infrastructure
• Use AI to scale code review, vulnerability triage, and exploit-pattern detection
• Own the bug bounty program and turn findings into fixes and regression tests
• Lead security incident response, root-cause analysis, post-mortems, and disclosure coordination
• Partner with engineering teams on secure-by-default APIs, code-review standards, and threat models
• Engage with auditors, researchers, white-hats, and the Move security community
• Monitor threats including bridge exploits, MEV, signature malleability, oracle manipulation, governance attacks, and validator collusion
