About Kyber

Kyber is an open-source SDK and platform to control remote machines, from Remote Desktop to Robots Teleoperation/Teleobservation. Kyber is a multi-stream and multi-actuator transport in extremely-low latency, over the quic protocol.

Clients use Kyber to control robots, drones, desktop, servers in the cloud or just remote rendering of interactive 3D programs. Kyber is done for Remote RealTime, where every millisecond matters.

Kyber is developed by engineers from the VLC and FFmpeg community, and we code in Rust, in C and in assembly. We have some development in Go too.

We're a quite technical team, but cool to work with.

We are based in Paris area and open to Remote Work in Europe. Full time only.
