• Contribute to FinOps initiatives by providing visibility into cloud usage, identifying opportunities for optimization, and supporting cost-aware engineering decisions.
• Optimize application performance and resource usage on Kubernetes through tuning, scaling strategies, and deep performance analysis.
• Provide guidance on reliability-first design, instrumenting code for observability, and using dashboards (Grafana, Cost Explorer, or similar) to drive incident response and operational insights.
• Support incident management processes and postmortems, driving continuous improvement across reliability and efficiency.
• Mentor SREs and advocate for best practices in automation, observability, reliability, and financial accountability.
