Job Title

Tier 1 Application Production Support Specialist

Job Summary / About the Role

ATT is seeking a technically strong and self-sufficient Tier 1 Application Production Support Specialist to provide 24x7 support for critical enterprise integration, messaging, and event-driven applications. This is not a pure monitoring or escalation role. The ideal candidate is expected to independently identify root causes, apply fixes, and resolve the majority of incidents without Tier 2 involvement. Tier 2 is engaged only for complex or architectural issues that go beyond Tier 1 resolution scope. The candidate must have solid working knowledge of the full technology stack and the ability to triage, diagnose, and remediate issues end-to-end.

Key Responsibilities

• Provide 24x7 support for incidents, alerts, and operational issues with a strong bias towards independent identification and resolution.

• Triage and diagnose incidents using logs, monitoring dashboards, and platform knowledge; resolve issues directly without defaulting to escalation.

• Engage Tier 2 only when incidents involve architectural complexity, infrastructure-level failures, or changes beyond Tier 1 resolution authority.

• Support client-submitted iTrack incident tickets and maintain end-to-end ticket ownership including resolution and closure.

• Respond to PagerDuty and automated alerts; validate, investigate, and remediate before escalating.

• Monitor production and non-production environment health; proactively identify anomalies and take corrective action.

• Monitor application support mailboxes and manage operational follow-through.

• Provide C2W emergency support as the first responder; independently handle and resolve wherever possible.

• Share client profile data and usage reports on request.

• Maintain clear incident communication to clients even when Tier 2 is engaged.

• Track and report operational metrics including MTTR and ticket resolution trends.

• Develop and maintain Tier 1 SOPs and operational runbooks based on real resolution patterns.

Required Qualifications / Must-Have Skills

• 3+ years of experience in application production support with a strong track record of independently diagnosing and resolving incidents.

• Solid working knowledge of the full technology stack in scope including event streaming platforms, integration middleware, AKS-hosted microservices, and observability tooling.

• Hands-on experience with incident lifecycle management in ticketing systems (iTrack or equivalent), including root cause identification and resolution documentation.

• Proficient with Splunk, PagerDuty, Prometheus, and Grafana for active troubleshooting and issue resolution, not just monitoring.

• Hands-on operational experience with Kubernetes, especially Azure Kubernetes Service (AKS), including pod-level diagnostics, restarts, and health investigation.

• Practical working knowledge of Confluent Kafka and Azure Event Hub: consumer lag analysis, topic health checks, and message flow troubleshooting.

• Solid SQL/Postgres skills for data-level investigation and validation during incidents.

• Working ability to read and interpret Java, Spring Boot, and React application logs for issue identification.

• Basic Python scripting capability for operational checks and quick-fix automation.

• Good Linux/Unix command-line skills for real-time log analysis and system diagnostics.

• Strong written and verbal communication skills for incident updates, resolution documentation, and client coordination.

• Willingness to work in rotational 24x7 shifts.

Good-to-Have / Nice-to-Have

• Awareness of hybrid streaming ecosystems including Confluent Cloud, AWS-MSK, and Apache Flink.

• Exposure to IBM Sterling Integrator integration flows for context during incident triage.

• Telecom or high-availability enterprise support experience.

• Experience with CI/CD-driven deployment pipelines in a support context.

Experience Level

Associate to Mid-Level (typically 3 to 5 years)

Location / Work Mode

Onsite (Hyderabad / Bangalore or designated ATT location)
