Perform incident resolution, root-cause analysis, and problem management within defined SLAs and quality standards.
Plan and execute patching, upgrades, and migrations, including server upgrades, OS hardening, and cloud or on-prem transitions (AWS/Azure).
Implement and monitor backup, disaster recovery, and security controls, ensuring systems meet availability, integrity, and confidentiality requirements.
Create and maintain accurate documentation, including runbooks, SOPs, network diagrams, and configuration records.
When required, provide oversight, mentoring, and structured guidance to team members to ensure adherence to company policies, procedures, and timelines.
Collaborate with US stakeholders and internal teams, communicating clearly on technical status, risks, and action plans.
