• 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:

• Strong experience with Docker, Kubernetes, EKS, container orchestration, and cloud-native operational practices.

• Strong understanding of Identity and Access Management, including IAM, RBAC, OAuth2, OpenID Connect (OIDC), SAML, Single Sign-On (SSO), and enterprise federation patterns.

• Experience implementing observability, monitoring, logging, tracing, and alerting solutions using CloudWatch, Grafana, Datadog, Prometheus, OpenTelemetry, ClickHouse, or equivalent platforms.

• Strong understanding of distributed systems, platform resiliency, disaster recovery, high availability, scalability, and performance optimization. 

• Strong scripting and automation experience using Python, Bash, PowerShell, or similar technologies. 

• Experience with FinOps practices, including cloud cost optimization, resource utilization analysis, tagging strategies, budget governance, and cost reporting. 

• Strong understanding of cloud security and compliance frameworks, including encryption, secrets management, vulnerability management, audit logging, security monitoring, and secure software delivery practices.
