  • Advanced troubleshooting and debugging experience across the Java technology stack, including API- and network-level investigation.
  • Hands-on experience with application monitoring and observability tools such as AppDynamics, Dynatrace, Splunk, and ELK.
  • Understanding of Linux and middleware platforms such as WebSphere, and experience tuning Linux, Windows, and network infrastructure.
  • Knowledge of cloud- and container-based architectures, including Docker and Kubernetes.
  • Experience with relational database technologies such as Oracle or DB2, including writing SQL queries and producing reports from databases and Splunk.
