Responsibilities

Provide end-to-end operational ownership and 24/7 production support for large-scale Java and JEE applications, with a focus on availability, resilience and rapid service recovery.
Participate in an on-call rotation, respond to alerts, triage incidents and lead technical investigation calls for escalated production issues.
Diagnose complex application, infrastructure, database and network issues using application performance monitoring tools and detailed log analysis.
Lead root-cause analysis and post-incident reviews, translating findings into practical actions that prevent recurrence and reduce mean time to recovery.
Design, implement and continuously improve observability capabilities for large-scale Java applications using tools such as AppDynamics, Dynatrace, Splunk and ELK.
Identify monitoring and performance gaps and develop effective health rules, alerts, dashboards and synthetic monitoring solutions.
Produce performance analyses, operational reports and knowledge-base documentation that improve system visibility and support informed decision-making.
Identify and implement automation and self-remediation opportunities that reduce manual effort, improve detection and accelerate incident response.
Integrate observability and service-management platforms, including AppDynamics, Splunk, PagerDuty and ServiceNow, to strengthen incident detection, escalation and resolution workflows.
Configure and tune alerts, escalation paths and operational workflows to improve signal quality and reduce unnecessary operational noise.
Support APIs, microservices, containers and other modern application architectures across complex production environments.
Review and create network rules and configure network appliances to investigate and resolve connectivity issues.
Develop practical solutions during incidents and unplanned events to mitigate customer impact and restore service quickly.
Create and maintain technical guides, implementation plans, validation checklists, operating procedures and post-incident reports.
Provide next-level technical support, coaching and day-to-day guidance to Application Operations Analysts and Specialists.
Contribute to reliability and operational-improvement initiatives that support the continued evolution of Interac’s SRE practices and next-generation platforms
