• Implement and manage observability solutions, including monitoring, centralized logging, tracing, alerting, dashboarding, and operational analytics.
• Support Kafka/MSK platform operations, including topic management, access controls, capacity planning, monitoring, scaling, and disaster recovery.
• Partner with Engineering teams to improve platform reliability, scalability, security, performance, and operational supportability.
• Drive DevSecOps practices through integration of security scanning, policy enforcement, infrastructure validation, container security, dependency management, and compliance checks within CI/CD pipelines.
• Perform platform performance tuning, capacity planning, backup and recovery validation, disaster recovery testing, and business continuity readiness activities.
• Drive FinOps initiatives by monitoring cloud consumption, optimizing resource utilization, improving cost efficiency, and implementing governance controls.
• Troubleshoot production issues, perform root cause analysis, and drive corrective and preventive actions for business-critical systems.
• Contribute to platform standards, operational runbooks, automation initiatives, engineering best practices, and continuous improvement programs.

Must Have Skills
