We are a cloud-native SaaS machine data analytics platform, solving complex monitoring problems for DevOps, SecOps and ITOps teams.  Our customers, including Airbnb, Twitter, BBC and Toyota, choose our solution because it allows them to easily monitor and optimise their large scale applications.

Our micro services architecture in AWS ingests hundreds of TB daily across many geographic regions. We also have short release cycles and no legacy versions to maintain. We write in Scala and use open-source technologies such as Kafka, Kubernetes and Cassandra.

The SRE team is unique in Sumo Logic as it doesn’t own any product service, you will work towards the whole codebase of the Sumo Logic product. You will identify the weakest links in either reliability or performance, research and benchmark possible improvements, and implement solutions in cooperation with the owning teams. You will not focus narrowly, there’s a broad spectrum of topics and projects you might get involved in.
