Senior Windows Kernel Engineer

The Windows Kernel Integration Team is a multi-discipline team that works across the company to develop novel observability, monitoring, and security collection capabilities for all of Datadog's specialized products. Through low-level user and kernel APIs, the team collects all the signals that are required to power some of our most impactful products like Network Performance Monitoring (NPM), Universal Service Monitoring (USM), Cloud Security Management, and several new and upcoming systems. Our goal is to provide complete visibility into wherever is needed to enrich existing Datadog products, and build new ones, without requiring users to deploy additional agents or libraries in their stacks. The team is composed of a set of Microsoft Windows experts who build custom drivers to instrument several layers of the OS stack. This group partners closely with Datadog's eBPF team that builds similar solutions on Linux.
