Vulnerability Management: Maintain and optimize a vulnerability management CI/CD pipeline within our container/application delivery infrastructure. You will adapt proven methods to align security goals with business objectives, even when guidance is light.
Cross-Functional Collaboration: Partner with development and infrastructure teams to enforce secure coding practices and remediation strategies. You will adapt your messaging across teams to reduce misalignment and move security work forward.
Implementation & Tooling: Build and maintain the frameworks and tooling for enterprise security, ensuring that security guidelines are clear and actionable for the broader engineering organization.
Incident Response: Play a key role in incident response and forensic investigations. You will weigh context and data thoughtfully to make smart decisions during high-pressure situations.

Security Testing: Mastery of SAST, DAST, and IAST tools, with the ability to perform manual validation testing to confirm findings.
Security Principles: Deep knowledge of the OWASP Top 10, Mitre Top 25, and secure coding practices.
Analytical Problem Solving: Ability to assess complex, ambiguous situations to identify root causes and provide thoughtful input on difficult security topics.
Communication: A track record of earning credibility with peers through clear, direct communication and a passion for mentoring others.
Compliance & Frameworks: Experience working with cloud security concepts and compliance frameworks such as SOC 2 and PCI.
