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.
Partner with stakeholders to align DevOps initiatives with business objectives, including uptime, deployment velocity, and cost efficiency.

Strong understanding of CI/CD pipelines (GitHub Actions, Jenkins, XLR etc.).
Proficient in scripting and programming (Bash, Python, Java).
Experience with monitoring and observability platforms (Prometheus, Grafana, Druid, Splunk, Loki).
Excellent communication skills and the ability to work effectively with Developers, QE, Operations and support teams.
Experience with FinOps or cost optimization in cloud environments
Demonstrated ownership mindset, prioritization skills, and ability to thrive in a fast-paced, multi-tasking environment.
