Responsibilities

  • AI Security Governance: Evaluate and establish guardrails for the secure use of AI coding assistants (e.g., Copilot, Cursor, Claude) within the engineering organization, including policy development around AI-generated code review, training data exposure risks, and prompt injection vulnerabilities in AI-integrated applications.

  • Secure SDLC Integration: Work closely with development teams to integrate security into the SDLC, including threat modeling, secure code reviews, and security testing.

  • Vulnerability Management: Identify, triage, and remediate security vulnerabilities through static and dynamic application security testing (SAST/DAST) and software composition analysis (SCA) tools.

  • **Security Assessments & Penetration Testing: **Conduct manual and automated penetration testing of web, mobile, and cloud applications to detect security flaws.

  • Secure Code Review: Analyze source code using both manual review and AI-assisted code analysis tools (e.g., GitHub Copilot Autofix, Semgrep, or similar) to surface vulnerabilities earlier in the development cycle and deliver actionable, in-context remediation guidance to developers.

  • **Threat Modeling & Risk Analysis: **Perform threat modeling to anticipate potential attack vectors and improve security architecture.

  • DevSecOps Enablement: Support and enhance DevSecOps initiatives by integrating AI-assisted security automation within CI/CD pipelines, including AI-powered SAST/DAST tools and LLM-based code scanning to accelerate vulnerability detection at the point of commit.

  • **Incident Response & Remediation: **Assist in investigating security incidents related to applications and work with engineering teams to remediate threats.

  • **Security Awareness & Training: **Educate and mentor developers on OWASP Top 10, SANS 25, and other security best practices.
