This is what your day will look like

As a Technical Support Specialist L2, you provide second-level technical support and take ownership of restoring service when incidents cannot be resolved at L1. You are the escalation point for complex incidents requiring advanced diagnostics across application, middleware, infrastructure, and database layers. You use deep troubleshooting techniques (logs/metrics/traces/queries), coordinate resolution with IT Service Managers, L3/DevOps and external providers, and ensure service recovery within agreed targets.

You also strengthen reliability through root-cause analysis, post-incident reviews, and continuous improvements in monitoring and automation.

Advanced Troubleshooting & Incident Resolution

• Perform advanced troubleshooting using logs, metrics, traces, and database queries.
• Own complex incidents, conduct deep root cause analysis, and implement workarounds to restore service.
• Handle code-level, architectural, and systemic issues before escalation to L3/development teams and ensure temporary mitigations/workarounds to restore service while permanent fixes are developed.

Reliability & Continuous Improvement

• Contribute to post-incident reviews with clear findings and corrective actions.
• Improve monitoring, alerting, and observability to reduce noise and strengthen service stability.
• Support automation and resilience improvements where applicable.

Changes, CI/CD Safety & Release Support

• Support production changes, hotfixes, and configuration updates within controlled change and release processes.
• Contribute to CI/CD safety, release strategies, and rollback mechanisms.
• Provide support for both production and lower environments (such as staging, testing, and development), ensuring issues are identified and resolved across all stages of the deployment lifecycle.

Collaboration & Interfaces

• Work closely with DevOps, platform, development, and architecture teams to ensure production readiness.
• Support L1 teams by improving runbooks, monitoring, and knowledge transfer (shift-left).
• Coordinate with external vendors and validate the quality of delivered fixes.

You come with

• Degree in Computer Science / IT / Software Engineering, or equivalent practical experience.
