Senior Software Engineer - Bits

Twitch is building the future of interactive entertainment, and our web client engineering team is preparing to scale to execute on critical product initiatives like Cheering with Bits, Subscriptions, Affiliates, Twitch Prime, and many great social interaction features.

Our Seattle office is focused on exciting new e-commerce initiatives in 2017! We’re looking for engineers that love delighting people with incredible products and user experiences. On the Commerce team, you’ll work closely with our other engineering and product teams to craft a beautiful and engaging product, collect feedback, and iterate quickly.

We value expertise in programming for the Web (including an understanding of modern JS tooling and cross-browser compatibility issues) and sensibilities for design and UX. The web client is written with Ember.js, builds using Ember CLI, uses ES6 features via Babel, and manifests backend systems like chat and video as user-facing products.  We also are building some new features in React.js.

You’ll write a lot of code, but you’ll also mentor engineers around you and do whatever needs to be done for the team and product initiative to succeed.


  • You’ll brainstorm with designers and product managers to design new features
  • You’ll work with backend engineers to specify the APIs that will power these features
  • You’ll implement experiments and collect data with our data scientists to drive subsequent iterations on these features
  • You’ll identify and uphold frontend engineering best practices
  • You’ll help our support team triage bugs, respond to user feedback, and fix production issues
  • You’ll participate in code and design reviews, teaching and learning from other engineers
  • You’ll have opinions about the user experience and contribute to the design of the solutions we ultimately build
  • Level up the organization around you through code reviews and engineering best practices
  • You’ll feel responsible for the quality of the features you ship
  • You’ll push code to production several times a day if necessary


  • 4+ years of hands-on experience building JavaScript web applications.
  • You have demonstrated past experience working on user interfaces and an eye for detail.
  • Experience with modern JavaScript libraries and tooling (ES6, Ember, React, etc.)
  • You have strong CS fundamentals and value rigor in engineering
  • Experience building consumer-facing web applications
  • Experience with modern browser technologies and cross-browser compatibility issues
  • Strong sensibilities for UX and design
  • You are equally excited to build a minimum viable product quickly as you are cementing a proven feature in maintainable and tested code.
  • Strong organizational and communication skills
  • You thrive in loosely structured environments
  • You are intellectually curious, passionate, inventive, and eager to grow
  • You focus on quality, sweat the details, and delight our users


  • Full benefits, including medical, dental, vision and life
  • 401(k) savings plan with a company match
  • Orca Card to pay for your commute from anywhere in the Seattle Area
  • Catered daily lunch
  • Unlimited snacks and drinks
  • Corporate gym membership
  • Flexible time off policy
  • Top of the line technology to help you build our own workspace
