About the Role

Twitch processes a massive amount of live video channels and distributes them using the largest dedicated live video CDN in the world, delivering over 25Tbps to more than 5MM concurrent viewers. In addition to serving Twitch traffic, our video platform is offered as Amazon Interactive Video Service, an AWS service that allows the creation of a live video streaming platform with only a few lines of code.

The Video Infrastructure Performance Engineering team delivers hardware and software purpose-built for video processing at scale, which includes everything from designing components/servers/racks, to planning internal product roadmaps, to developing low-level OS/kernel software, and to partnering with other internal service teams to bring solutions to production.

Working with the Video Infrastructure Performance Engineering team, you will use your software engineering, networking, and high-performance computing experience to identify and remove performance bottlenecks in services across the video platform. We've already built the lowest latency high-scale HLS distribution system on the planet. You will help us get exceptional performance out of our edge and origin data infrastructure world-wide to improve the efficiency of our low-latency and real-time video products.

You Will:

  • Survey the landscape of services that run on our infrastructure and characterize their performance to identify the best opportunities for improvement
  • Build prototype software to demonstrate the best hardware performance and partner with internal service teams to adopt new technologies
  • Build low-level, optimized software libraries and applications in C/C++/Rust/Golang and deploy them to production environments
  • Improve the density of network-intensive, compute-bound workloads like video ingest and media distribution (e.g. CDN optimization)

You Have:

  • Experience characterizing and optimizing C/C++/Rust/Go applications for performance
  • Experience implementing network packet processing techniques such as kTLS, NIC crypto offload, and user-mode dataplane processing (like DPDK)
  • Hands-on experience with the modern Linux distributions and kernel customization
  • Hands-on experience optimizing networking protocols like SSL/TLS/HTTP/HTTPS
  • Hands-on experience with video protocols like RTMP/RTMPS and WebRTC/RTP/SRTP/DTLS
  • 8+ years of experience improving application performance at the system/solution level, doing everything from design to development to deployment to monitoring in production environments

Bonus Points

  • Experience deploying application-specific infrastructure
  • Experience driving the use of containerization or virtualization
  • Experience with video codecs and standards like H.264/H.265 and HLS/LL-HLS
