• Vulnerability Management Triage and prioritize application-layer vulnerabilities and guide engineering teams through remediation.
• Developer Enablement Deliver secure development and coding training; create resources to reduce recurring vulnerabilities.
• Bug Bounty Management Oversee Bug Bounty program, validate findings, and ensure timely resolution.
• Incident Response Leadership Lead investigations for application-layer security incidents and conduct post-incident analysis.
