Senior Software Engineer

About the Observability Patronus Team
The Observability Patronus team is responsible for building and operating Atlassian's core observability platforms, including Grafana Mimir and self-hosted Sentry (FedRAMP). Our mission is to empower engineering teams with reliable, scalable, and compliant monitoring solutions that ensure the health and performance of Atlassian's products.

The Role

As a Senior Software Engineer in Observability, you'll be building the platforms and defining practices that keep Atlassian's products rock-solid and lightning-fast for millions of users.

We're not talking about your average telemetry herewe're collecting, moving, and ingesting multiple petabytes of data every single day, and making it all available within seconds. It's a massive scale, and it's critical to everything we do. You'll empower hundreds of Atlassian engineering teams with world-class observability solutions, helping them ship reliable, high-quality products our customers love.

This is a platform team that sits at the intersection of infrastructure and software engineering. Some candidates expect all software engineering, others expect all infrastructurehere, you'll need to be passionate and skilled in both. You'll be building and operating ultra-high-scale systems for metrics, including one of the world's largest Mimir clusters (at 10x the certified load!). You'll face architectural and scaling challenges that will stretch your skills and imagination.

If you're excited by big challenges, love working with smart people, and want to make a real impact, you'll fit right in.
