About Grafana Labs:
There are more than 700,000 active installations of Grafana around the globe, monitoring everything from beehives to climate change in the Alps. The instantly recognizable dashboards have been spotted everywhere from a SpaceX launch and Minecraft HQ to Wimbledon and the Tour de France. Grafana Labs also helps companies including Bloomberg, JPMorgan Chase, and eBay manage their observability strategies with full-stack offerings that can be run fully managed with Grafana Cloud, or self-managed with Grafana Enterprise Stack. The Grafana stack has grown to include two other open-source projects, Grafana Loki (for logs) and Grafana Tempo (for traces)
This is a remote position, and we are considering candidates in the North, Central & South Americas regions.
About Grafana Cloud:
Grafana Cloud is our composable observability platform that integrates metrics, logs, and traces with Grafana. It allows our customers to leverage the best open source observability software – including Prometheus, Cortex, Loki, and Tempo – without the overhead of installing, maintaining and scaling their own observability stack.
Our Grafana Cloud pipeline moves millions of data points, loglines, and traces per second from our customers’ environments into a highly available, low-latency stack that processes and stores the data, and serves it to dashboards and alerting tools. We aim to grow this to hundreds of millions per second, and it's critical that as we grow, we improve our performance, increase our reliability, and do it all more efficiently.
You would be joining one of our Cloud squads, whose responsibilities span from adapting and delivering our open-source offerings to a cloud environment that can support millions of users, writing software that allows those users to easily send data from within their infrastructure, or helping to build monitoring and alerting solutions. Our tech stack is mostly made up of services written in Go, running on multiple Kubernetes clusters that leverage Google’s Cloud Platform.
Our culture is remote-first and our engineering organization is largely remote. We provide guidance and meet regularly using video calls, so an independent attitude and strong communication skills are a must
