Drive observability and reliability through monitoring, logging, and alerting systems (Prometheus, Grafana, Druid, Splunk etc.).
Foster innovation and continuous improvement, adopting new tools and practices to increase efficiency, scalability, and cost optimization.
Contribute to hands-on coding and automation efforts when needed — lead by example.
