• Oversee IAM architecture including RBAC models, SSO, MFA, and least-privilege access controls.
• Lead vulnerability management, posture monitoring, and audit compliance initiatives.
• Ensure secure image pipelines, patching strategies, and secrets management.

Monitoring, Observability & Reliability

• Architect observability frameworks integrating logs, metrics, and tracing systems.
• Drive SRE practices including SLIs/SLOs, alerting strategies, and incident response improvements.
• Continuously improve system reliability, availability, and operational insights.

Cost Optimization & Governance

• Define and implement cost governance frameworks, budgets, and optimization strategies.
• Drive initiatives for right-sizing, tagging compliance, and usage optimization.
• Provide cost visibility dashboards and executive-level reporting.

Leadership & Collaboration

• Mentor L1/L2 engineers and conduct technical reviews and knowledge sharing.
• Collaborate with DevOps, Security, and Application teams to align platform capabilities.
• Lead technical discussions, design reviews, and incident post-mortems.
• Maintain high-quality documentation, standards, and reusable frameworks.
