• Ensure automated provisioning, configuration, and policy enforcement across environments.

Security & Governance

• Implement cloud and infrastructure security controls: IAM, KMS, SIEM/monitoring, security baselines, and compliance frameworks.
• Collaborate with security teams to drive zero‑trust, identity governance, and audit readiness.

Leadership & Collaboration

• Act as the technical escalation point for complex design, performance, or production issues.
• Mentor infrastructure, cloud, DevOps, and operations engineers.
• Work closely with application, security, and network teams to deliver integrated, end‑to‑end solutions.
• Provide architectural guidance, documentation, and executive‑level presentation support.
