Do you like to solve difficult problems in C/C++? Advanced memory management, lock-free, wait-free data structures, real-time processing, latency guarantee - these are just a few challenges you are going to face.

It's a challenge to design and implement cloud software that scales on very powerful servers (100+ cores, terabytes of memory, 100 Gbs network connections, NVMe over Fabric storage) and coordinates in clusters across hundreds of such nodes.

As our Linux C/C++ Software Engineer, you'll deal with the critical components in our stack, like the real-time messaging, signaling and media servers, HubRing database and HubStor distributed storage.

• Design and develop new features for existing servers or implement new ones from scratch
• Contribute to OpenSource projects such as Asterisk, Kamailio, NGINX, Redis, HAProxy, PowerDNS, ZFS, Kubernetes
• Optimize performance based on profiling information
• Investigate security and undesired conditions (e.g.: memory leaks, races)
• Investigate performance issues (e.g.: latency, throughput)
• Make peer reviews - design review, code review, documentation review
• Coordinate with other teams in regards to the managed components
