Library Software Engineer - Java (APM)

Datadog's APM team is building a world-class tracing product that helps developers see inside complex distributed systems. We're building rock solid libraries to trace requests as they flow across servers, databases, caches and microservices in all the major languages. We're investing heavily in systems to process a massive firehose of data - fast data pipelines, scalable storage systems and a slick UI to tie it all together. We are a very distributed team; we have teams in New York and Paris and remote folks scattered around the world. Come and join a team that cares about building software the right way.

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