Build dashboards and operational alerts using Splunk, Kibana, AppDynamics, Instana, or Datadog.

Troubleshoot production issues by analyzing application logs, performance metrics, event flows, and database behavior.

Collaborate with product owners, architects, QA, database, security, and DevOps teams.

Drive application resiliency, performance improvement, cloud adoption, and engineering automation.

Strong understanding of API security, OAuth 2.0, TLS, and encryption.

Experience with Jenkins, Maven, Gradle, GitHub, SonarQube, and CI/CD.

Experience with automated unit, integration, behavioural, and performance testing.

Production-support experience using enterprise monitoring and logging tools.

Proven ability to lead technical delivery and coordinate engineering activities.
