What You'll Own:

  • Lead Application Security testing projects — most likely AI-assisted — and drive remediation of identified vulnerabilities
  • Design and run adversarial testing campaigns across the full Buildkite environment
  • Build automation for both AppSec and adversarial testing workflows

What Success Looks Like:

  • Meaningful adversarial attacks run against Buildkite, with documented results
  • AppSec vulnerabilities identified and remediated
  • Automation built for both functions — not just processes documented

What We're Looking For:

  • 5–7 years in security roles with a genuine offensive or AppSec focus
  • Industry-relevant certifications (OSCP or equivalent) — or equivalent demonstrated capability
  • Experience securing AWS and cloud-native environments
