Zulip
Zulip server and web application. Open-source team chat that helps teams stay productive and focused.
Zulip is building the world’s best collaboration platform, and we’re committed to keeping it 100% open source. Zulip is the only modern team chat app designed for both live and asynchronous conversations. Our product serves as the communication hub for businesses, open-source projects, educators and communities around the world.
We’re looking for a senior backend/infrastructure engineer to join our small core team and build, operate, and scale Zulip — both as we run it on Zulip Cloud, and as thousands of self-hosters run it themselves. The Senior Backend/Infrastructure Engineer will work across backend features, performance, and infrastructure; review code from both staff and open-source contributors; and share responsibility for keeping Zulip Cloud production healthy. You will also have the opportunity to provide technical direction and mentorship to the team.
