• Support the implementation of cloud workload protection and security solutions such as Prisma Cloud CWPP/CSPM.

5. SRE, Observability & Operational Quality

• Lead structured Root-Cause Analysis (RCA) for complex technical incidents and implement measures to prevent recurrence.
• Develop and maintain telemetry, logging, monitoring, and operational dashboards to support system performance, reliability, and security.
• Support change management, release activities, and operational support in accordance with ITIL-aligned processes.
• Contribute to service reliability, availability, and continuous improvement initiatives.

Key Qualifications & Skills

• Demonstrated experience in cloud engineering, infrastructure automation, and DevOps/SRE delivery, including experience providing technical guidance or leading technical projects.
• Hands-on technical proficiency in AWS or Azure.
