About the Role

We are an innovation team within R&D, building internal products that power our Threat Intelligence and Detection authoring teams to secure our customers.

Working at petabyte scale, we build systems that enhance existing detections and unlock entirely new detection capabilities. We are mission-driven to secure the customer.
