- Automate and simplify Kubernetes clusters lifecycle management, upgrades, and observability workflows.
- Implement monitoring and alerting systems using tools such as Prometheus, Grafana, or Elastic Observability to meet service-level objective (SLOs).
- Collaborate with security teams to integrate and enforce security controls and compliance requirements within the container platform.
- Work with application teams to improve platform usability, streamline onboarding, and reduce operational toil.
- Respond to incidents and perform post-incident reviews, driving continuous improvement and operational excellence.
- Contribute to the reliability engineering culture, fostering shared responsibility for system availability and performance.
