ABOUT

---

Video lies at the heart of the Gather experience, providing a low-latency, seamless experience for the spontaneous interactions we're known for. Our video infrastructure handles thousands of concurrent users, spanning all continents of the world.

Unlike traditional room-based video infrastructure, our video infra allows any two users to have a directional audio/video connection — enabling experiences such as podiums, where a speaker can address a large audience while the audience remains quiet to the speaker, yet the audience can still mingle amongst their neighbors, just like in real life. Our video infrastructure spans 4 data centers, ~500 servers, and features an SFU-based design built in-house.

ABOUT the role

---

As a video systems engineer, you would take responsibility (along with a small team) for the design and implementation of this integral part of our product.

Where you'll make an impact:

• Increase the maximum number of simultaneous videos we can reliably display to users beyond our current maximum of 9.
• Increase the maximum size of a reliable fully connected audio conversation beyond our current maximum of 20.
• Increase the quality of videos we can reliably display to users.
• Increase the maximum size of broadcasts from our current limit of 1-to-200 by forwarding streams between SFUs.
• Degrade quality more gracefully for bandwidth or CPU constrained devices, as well as better handling of spurious spikes in latency/congestion.
• Make the system better able to recover from various faults and errors
• Set up metrics to get a better handle on what quality of service our users are experiencing, and to inform further improvements.
• Build automated tests to ensure the reliability and performance of our video infrastructure as we change it
