• Mentor junior/mid-level engineers on FinOps tooling, practices, and cost-conscious engineering
• Identify and lead multi-quarter cost optimization initiatives with measurable ROI, presenting outcomes to engineering leadership

• Strong scripting/automation skills (Python, Go, or similar) and IaC experience (Terraform)
• Experience with Kubernetes cost tooling (Kubecost, OpenCost) and observability stacks (Grafana, Prometheus)
