• Contribute to incident investigations, root cause analysis and long-term security improvements.

• Develop security standards, documentation, playbooks and developer guidance.

• Define and track security metrics to improve visibility, coverage and risk reduction.

• Evaluate emerging security technologies and help drive adoption of tools that create value for engineering teams.

• Promote secure AI-assisted development practices and responsible use of AI technologies.

• Foster a strong security culture through collaboration, enablement and knowledge sharing.

About You:
