• Provide SME‑level guidance on architecture, provisioning, configuration, and operational best practices.
• Own high‑priority, complex issues and ensure timely resolution and proper RCA with corrective actions.
• Drive reliability improvements through automation, observability, and SRE practices.

Team Leadership & Mentoring

• Mentor, coach, and develop L1/L2/L3 engineers on technical and process skills.
• Conduct code reviews for automation scripts and configuration management workflows.
• Promote knowledge sharing through KT sessions, runbooks, SOPs, and internal workshops.
• Act as escalation point for the team during major incidents.

Proactive Operations Management

• Identify operational inefficiencies and lead optimization initiatives.
• Drive proactive monitoring, trend analysis, and identify reliability risks before failures occur.
• Define and measure operational KPIs such as SLAs, SLOs, latency, uptime, and MTTR.

ITSM, Incident & Change Leadership

• Lead Major Incident Management (MIM) calls for infra‑related issues.
• Ensure adherence to change/process governance and quality documentation.
• Champion Problem Management by driving deep RCA and preventive actions across teams.

Automation, SRE & Innovation

• Architect and implement automation workflows using Shell/Bash/Python/Ansible.
• Enhance observability by contributing to dashboards, alert rules, logs, and metrics.
• Accelerate adoption of GitOps, config‑drift controls, self‑healing scripts, and infrastructure-as-code practices.

Stakeholder Management

• Collaborate with platform owners, product teams, cybersecurity, and environment management teams.
• Provide regular updates, operational insights, and reliability metrics to leadership.
• Influence decision‑making with data‑driven recommendations.

Lifecycle, Modernization & Migration
