Senior Software Engineer - Windows system internals

The Windows Products team at Datadog, part of the Networks & Endpoints group, is dedicated to delivering a best-in-class observability experience with the Datadog Agent for Windows while establishing Windows as a first-class platform across all Datadog products, such as Network Performance Monitoring (NPM), Universal Service Monitoring (USM), and a range of emerging and next-generation observability tools. We advocate for Windows users; whether managing servers, endpoints, or hybrid environments; by developing innovative observability, monitoring, and security collection capabilities to support the key services and technologies our customers rely on, while collaborating across the company to expand these offerings. Our mission is to provide robust, out-of-the-box observability solutions by enriching Datadog products tailored for Windows; ensuring feature parity, deep visibility, and operational excellence across every layer of the stack; without requiring the deployment of additional agents or libraries.

At Datadog, we place value in our office culture - the relationships and collaboration it builds and the creativity it brings to the table. We operate as a hybrid workplace to ensure our Datadogs can create a work-life harmony that best fits them.
