We are looking for a Senior Software Engineer to help us take REDAPL, our Referential Data Platform, to the next level. REDAPL is Datadog's main platform for tracking our customers' infrastructure resources and relationships. The platform enables products where customers can understand, keep track of, and gain insights into their infrastructure related to performance, cost, security, and more.

Many Datadog products use REDAPL today such as Cloud Security Posture Management, Resource Catalog, Cloud Cost Management, and Service Catalog and others - REDAPL ingests more than 4.5 million updates per second.

As a Senior Engineer, you will drive, lead and collaborate on projects both inside and outside the platform. You can expect to contribute to key technical decisions relating to our data ingestion, processing, and query pipelines.

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.

Contribute to design and drive high‑priority, high‑visibility projects to increase the platform’s value, resilience, and scalability across multiple teams.

Lead and guide other engineers through architectural platform decisions.

Provide input on prioritizing engineering‑led initiatives in short‑ and long‑term planning and roadmaps.

You have a BS/MS/PhD in a Computer Science, Engineering or related scientific field or equivalent experience.

You have worked extensively with multiple types of data stores.

You have led impactful technical initiatives in an environment where performance, cost efficiency, ease of use, and resilience/operability are first‑order concerns.





You have significant back‑end engineering experience and have built, and operated distributed systems to solve problems at a high scale.

You have experience working with Graph Databases such as Neo4j, Memgraph, JanusGraph, ArangoDB, Amazon Neptune or PuppyGraph.

You have a solid grasp of query planning or better yet – contributed to a production‑grade query engine or related projects (e.g. Trino, Calcite, Substrait, DataFusion, etc) ideally demonstrated through open‑source contributions or PMC membership on projects.

Datadog values people from all walks of life. Get to build tools for software engineers, just like yourself, and use the tools we build to accelerate our development.

Work with skilled, knowledgeable, and kind teammates who are happy to teach and learn.
