  • Assist development teams in understanding findings and implementing effective fixes
  • Support threat modeling and secure design reviews
  • Stay current with emerging vulnerabilities, attack techniques, and mitigation strategies
  • Document findings, recommendations, and best practices
  • Perform other duties as assigned

  • Experience identifying, exploiting, and remediating application vulnerabilities
    • Credit for published CVEs is a strong plus
  • Proficiency in one or more programming languages such as C++, Python, JavaScript, Rust
  • Experience configuring and operating static analysis tools (e.g., Coverity, Klocwork, SonarQube)
  • Experience configuring and operating software composition analysis tools (e.g., Snyk, Sonatype, Anchore, JFrog Xray)
  • Experience with fuzzing frameworks (AFL, AFL++, honggfuzz, or similar)
  • Experience with debugging, runtime instrumentation, or reverse engineering, including tools such as:
    • strace
    • eBPF
    • Ghidra or IDA Pro
  • Familiarity with threat modeling methodologies and frameworks such as MITRE ATT&CK
