Senior Site Reliability Engineer (SRE) – Observability & Kubernetes (8–12 yrs)

Cisco’s Cloud Collaboration Technology Group (CCTG) builds and operates large-scale, cloud-native collaboration platforms including Webex. The team focuses on delivering highly reliable, observable, and scalable infrastructure powering millions of users globally. You will work at the intersection of platform engineering, SRE, and observability, enabling engineering teams to operate resilient distributed systems.
 

As a Cloud Engineer (Grade 10), you will design and operate observability and infrastructure platforms supporting Webex microservices at scale. This role combines deep hands-on engineering with production ownership, where you will independently drive reliability, automation, and performance improvements across distributed systems.

• Design, build, and operate observability platforms (logging, metrics, tracing) for microservices
• Manage and optimize Kubernetes clusters across multi-region production environments
• Own and enhance CI/CD pipelines using Argo CD, Helm, and GitOps workflows
• Implement and manage infrastructure-as-code using Terraform on AWS
• Operate and scale monitoring ecosystems (OpenSearch/ELK, Prometheus, Grafana, Splunk, Kafka)
• Build automation for proactive detection and remediation of production issues
• Lead incident response, participate in on-call rotations, and drive post-incident improvements
• Ensure system security and compliance through patching and vulnerability management
• Collaborate with cross-functional teams to improve system reliability and scalability
• Contribute to distributed system design and platform engineering initiatives

• Kubernetes administration
• CI/CD with Argo CD and Helm
• Docker and container ecosystems
• Terraform or IaC tools
• Kafka or streaming systems
• Linux/Unix expertise
• Monitoring and alerting systems

As a part of core tech 90% of our work in based out of these skills.

• 8+ years of experience in DevOps, SRE, or platform engineering roles in production environments
• Hands-on experience operating Kubernetes at scale (multi-cluster, thousands of pods, Helm-based deployments)
• Strong expertise in observability tools (at least two): Prometheus, Grafana, OpenSearch/Elasticsearch, Splunk, Loki, or Logstash
• Proven experience with Infrastructure-as-Code (Terraform or equivalent) on AWS
• Proficiency in scripting or programming (Python, Golang, or Bash) for automation and CI/CD integration

• Experience managing Kafka / AWS MSK clusters and high-throughput streaming systems
• Hands-on experience with OpenTelemetry and distributed tracing frameworks
• Familiarity with security standards (ISO 27001, SOC 2, FedRAMP) and container hardening tools
• Experience with GitOps workflows (Argo CD), Helm bundles, and progressive delivery (canary/blue-green)
• Experience using AI tools (Copilot, Claude, LLM-based agents) for code generation, troubleshooting, or incident automation
