Senior Software Engineer (Fullstack) - Product

At Datadog, fullstack engineers build the end-to-end product experiences that power our observability platform. As a Senior Fullstack Engineer with a frontend focus, you’ll drive complex, user-facing features while contributing to the backend systems that support them. You’ll architect performant interfaces at scale, collaborating across disciplines to create seamless product experiences. This role is ideal for engineers who excel in frontend-led fullstack development and want to have deep ownership over product surfaces that impact customers directly. 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. Disclaimer: This is not a strict 50/50 frontend–backend split. The exact balance varies by team, project, and product area, and may shift over time. You’ll regularly contribute across the stack, but the role is designed for engineers who prefer and excel at frontend-led fullstack work.
