Responsibilities Triage, validate, and prioritize security vulnerabilities identified through manual reviews, automated tooling, bug bounty reports, and AI-assisted security analysis platforms. Participate in on-call rotation to support security incident triage, perform code reviews, and address security questions. Partner closely with engineering teams to drive remediation efforts, provide actionable guidance, and ensure timely closure of security findings based on risk and severity. Review security-related pull requests and code changes, providing guidance on secure implementation patterns and identifying potential vulnerabilities before production deployment. Analyze findings generated by AI-powered security agents and automation platforms, validate results, reduce false positives, and help drive remediation workflows across engineering teams. Collaborate with Product Security Architecture and development teams to improve vulnerability detection, prioritization, and remediation processes. Support security incident investigations and root cause analysis when vulnerabilities or application security issues are discovered.

Experience partnering with software engineering teams to drive remediation and risk reduction efforts. Strong understanding of common application security vulnerabilities (OWASP Top 10, API Security, authentication, authorization, secrets management, cryptography, etc.). Experience reviewing source code and identifying security vulnerabilities in modern programming languages and frameworks. Familiarity with security tooling such as SAST, DAST, SCA, IaC scanning, secrets detection, and vulnerability management platforms. Experience working with cloud-native architectures and public cloud environments (AWS preferred). Ability to evaluate security findings, distinguish signal from noise, and communicate risk-based remediation recommendations. Familiarity with AI-assisted development workflows, AI-powered security tooling, or LLM-based security use cases is a plus.
