• Strong web and API pentesting experience, especially in authorization (IDOR/BOLA, privilege escalation, role/tenant boundaries), authentication/session flows (tokens, identity integrations), and common vulnerabilities (injection, SSRF, deserialization, misconfigurations) with practical exploitation skills
• Advanced Burp Suite skills: manual validation, targeted fuzzing, authenticated testing, and workflow automation (extensions/macros)
• Experience writing Semgrep rules to detect insecure patterns and improve secure-by-default development
• DAST experience at scale: running or supporting authenticated scans, tuning coverage, and reducing false positives
• Clear written communication: concise PoCs and actionable remediation guidance for engineers

Nice to have:

• SaaS multi-tenant security testing experience
• OAuth2/OIDC/SAML depth
• Bug bounty triage
• Writing custom tooling or Burp extensions

• Own offensive testing: plan what to test, how deep to go, and how often; create clear, consistent reports and reusable playbooks
• Perform manual pentesting (main focus): test web apps and APIs, especially authentication/authorization, multi-tenant boundaries, and critical workflows; chain issues into realistic attack paths
• Use Burp Suite daily: validate and reproduce findings with advanced Burp features; build and maintain repeatable scopes, macros, and authenticated flows
• Run and improve DAST: execute and tune authenticated scans, reduce false positives, and work with CI/platform teams to scale scanning and manage credentials
• Drive remediation: deliver high-quality write-ups, partner with engineers to fix and retest, and help prevent regressions; ensure findings are tracked with the right severity and SLAs
• Improve security long-term: spot recurring patterns and help teams prevent them through standards, libraries, platform controls, and input to threat modeling/design reviews
