About The Role

The data engineering team is on a mission to create a hyper scale data lake, which helps find bad actors and stop breaches. The team builds and operates systems to centralize all of the data the Falcon platform collects, making it easy for internal and external customers to transform and access the data for analytics, machine learning, and threat hunting. As a senior engineer on the team, you will contribute to the full spectrum of our systems, from foundational processing and data storage, through scalable pipelines, to frameworks, tools and applications that make that data available to other teams and systems. Your primary toolset in your work will be Java microservices, Spark/Scala data processing (also some Flink), Kubernetes and AWS native tooling. Your primary focus will be owning our new graph database, which you will have a significant hand in building.
