Senior/Staff Software Engineer, Site Reliability (SRE) - Hubs Team

The Opportunity

At Mozilla, we believe that the “metaverse” – like the internet itself – should be open and accessible to all. That’s why we’re building Hubs.

Hubs empowers communities to gather in safe, private, decentralized virtual spaces where they are in control. Hubs fosters creativity and connection at a time when online interactions often lack the spontaneity and opportunity to delight, inspire, and build trust between people.

As a site reliability engineer on the Hubs team, you will be responsible for the availability, performance, efficiency, change management, monitoring, emergency response, and capacity planning of our services. You’ll help establish an SRE/DevOps culture on our engineering team and ensure those principles are carried throughout the development life cycle.
