Datadog, a global SaaS business, is seeking a Software Engineer specializing in Distributed Systems to join their team in Madrid, Spain. This role offers an exciting opportunity to work on cutting-edge technology in a fast-paced, high-growth environment.

As a Distributed Systems engineer at Datadog, you'll be at the forefront of designing, implementing, and running production-level foundational platforms that power their applications. Your work will involve creating data pipelines that ingest, store, analyze, and query billions of events per second in real-time from companies worldwide. These platforms are optimized for durability, high availability, low latency, internet-scale footprint, and operability.

Key responsibilities include building fault-tolerant, horizontally scalable solutions in multi-tenant environments, writing code in languages such as Go, Java, Rust, or C++, and utilizing open-source components like Kafka, Redis, Cassandra, and Elasticsearch. You'll have the opportunity to own meaningful parts of the service, make a significant impact, and grow alongside the company.

The ideal candidate should have a strong background in backend programming, experience with high-durability and low-latency problems, and the ability to work at a low level when needed. A BS/MS/PhD in a scientific field or equivalent experience is required. Datadog values simple designs, performance, and a passion for technology.

Datadog offers an attractive benefits package, including stock equity options, professional development opportunities, an inclusive company culture, and comprehensive health benefits. They operate in a hybrid work environment, allowing employees to balance office culture with work-life harmony.

Join Datadog to be part of a collaborative, pragmatic, and thoughtful people-first community where you'll solve tough problems, take smart risks, and celebrate one another's successes. This role presents an excellent opportunity for growth and impact in the rapidly evolving field of distributed systems and cloud technology.
