• Investigate complex problems using logs, databases, and metrics.
• Define relevant metrics for early problem detection and identify recurring failure patterns.
• Propose preventive measures and collaborate with development teams on structural problem resolution.
• Document and share knowledge while working effectively with other teams.

Requirements

Nice to have

• Experience with observability tools such as Grafana and the ELK Stack, including investigating functional problems through data.
