About the Falcon Platform:

Falcon is the CrowdStrike platform purpose-built to stop breaches via a unified set of cloud-delivered technologies that prevent all types of attacks — including malware and much more.

CrowdStrike stores more than 15 petabytes of data in the cloud that it uses to make decisions about upward of 1 trillion security events a day.

About the Role:

As part of the Cloud Engineering Platform Data organization you will build globally distributed, fault-tolerant and highly-scalable cloud-based systems using

microservices architecture. You will lay the foundation that will enable CrowdStrike to continue pushing the state of the art for security services. Many other teams will be leveraging the core pieces of infrastructure you help build to further enhance security products and make cyberspace a safer place.

You would be part of a team which is building a Global Query Engine ecosystem, a set of components that will enable internal and external partners to access and join data from multiple underlying stores. The technology is built in-house and powered by Cassandra, Elasticsearch/OpenSearch, Kafka, Kubernetes and Go.

This is an excellent opportunity to join our talented team of technology enthusiasts, learn and also contribute to one of the most revolutionary platforms in the cyber security space.… and don't worry if you don't know Go, we will teach you!
