• Lead audit preparation cycles: scope definition, evidence readiness, control documentation, and auditor-facing communication.
• Maintain audit-ready posture year-round, not as a sprint before each audit window.
• Partner with the Compliance function to ensure security controls satisfy both regulatory requirements and practical risk management objectives.
• Manage and develop the Senior DevSecOps Engineer, with the expectation of growing the security team over time.
• Serve as the internal authority on security for Engineering, Product, Compliance, Legal, and People Ops.
