• Partner with application teams, security teams, project stakeholders, vendors, and service providers to deliver stable and secure infrastructure services.
• Provide technical guidance and mentoring to engineers on infrastructure operations, Terraform, automation, and secure operational practices.
• Contribute to continuous improvement initiatives that raise operational maturity and service quality.

On‑call Support

• Participate in a 24x7 on‑call rotation to support critical platforms and services.
• Provide timely escalation support, incident response, and service recovery during production issues.
