Rockstar🎓
Top SchoolJack Baldry is a Senior Site Reliability Engineer based in London with 11 years of experience building and operating cloud-native infrastructure and developer platforms. He combines deep operational experience with hands-on DevOps and backend contributions to high-profile open-source projects such as Grafana, Loki, Mimir and Cortex, often improving packaging, CI/CD pipelines, and observability workflows. At Grafana Labs he focuses on scalability, packaging (RPM/deb), and documentation automation to make complex distributed systems more maintainable and testable. Previously he led DevOps at Oracle and built Kubernetes, Terraform and Puppet-based platform tooling at Grapeshot, demonstrating a strong blend of systems engineering and developer ergonomics. He’s as comfortable tweaking Jsonnet and Starlark in CI as he is tuning DynamoDB backoff settings, which reflects a pragmatic attention to both developer experience and runtime resilience.
