Senior Software Engineer - CDN Edge Performance

Job ID: 2310218 | Twitch Interactive, Inc.


About Us:

Twitch is the world's biggest live streaming service, with global communities built around gaming, entertainment, music, sports, cooking, and more. It's where millions of people come together to chat, interact, and make their own entertainment.
We're about community, inside and out. You'll find coworkers who are eager to team up, collaborate, and smash (or elegantly solve) problems together. We're on a quest to empower live communities, so if this sounds good to you, see what we're up to on LinkedIn and Twitter, get interviewing tips on Instagram, and discover projects we're solving on our Blog.

About the Role:

Twitch operates 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 CDN is offered as an AWS service, Amazon Interactive Video Service, enabling the creation of a live video streaming platform with only a few lines of code.
The Video Distribution team manages the software that operates that CDN, which includes everything from custom edge software that delivers video on thousands of hosts worldwide, to the graphing algorithms that manage our worldwide caching hierarchy, and to the complex and introspective algorithms that decide what server a user is assigned when they start playback.
Working with the Video Distribution team, you will use your low-level network protocol development experience to dive deep into next-generation media protocols and optimize the efficiency of Twitch video delivery at the edge. We've already built the lowest latency high-scale HLS distribution system on the planet. You will help us build the next generation of sub-second and real-time product offerings.

As a Senior Software Engineer you will report to the manager of the Video Distribution Edge and Backbone team.

You can be located in San Francisco, CA; Irvine, CA; Seattle, WA; New York, NY; Salt Lake City, UT; or Vancouver, BC. You can also be remote within Canada or the USA.

You Will:

• Design, implement, and deploy live video CDN edge delivery features using modern protocols like QUIC, WebRTC, and HLS.
• Squeeze every last iota of performance out of Twitch's edge compute by writing performant kernel and network code and investigating further optimizations like TCP offload.
• Validate performance improvements and prevent regression by defining and implementing repeatable automated performance tests.
• Work with client video teams to contribute to the next generation of Twitch by improving edge efficiency, lowering latency, and improving time to video.


  • 5+ years of non-internship professional software development experience
  • 5+ years of programming with at least one software programming language experience
  • 5+ years of leading design or architecture (design patterns, reliability and scaling) of new and existing systems experience
  • 5+ years of full software development life cycle, including coding standards, code reviews, source control management, build processes, testing, and operations experience
  • Experience as a mentor, tech lead or leading an engineering team


  • Bachelor's degree in computer science or equivalent
