Roku is changing how the world watches TV

Roku is the #1 TV streaming platform in the U.S., Canada, and Mexico, and we've set our sights on powering every television in the world. Roku pioneered streaming to the TV. Our mission is to be the TV streaming platform that connects the entire TV ecosystem. We connect consumers to the content they love, enable content publishers to build and monetize large audiences, and provide advertisers unique capabilities to engage consumers.

From your first day at Roku, you'll make a valuable - and valued - contribution. We're a fast-growing public company where no one is a bystander. We offer you the opportunity to delight millions of TV streamers around the world while gaining meaningful experience across a variety of disciplines.

About the Team

The Advanced Development organisation pushes beyond the boundaries of product lines to build new things. We think independently of standard shipping cadences and timelines, working on foundational technologies that will impact every Roku device in the future, and on ideas that no one has seen before in their living room. As this is an exceptional team, we are seeking unusual talent. As part of Advanced Development, the Developer Experience team specifically focuses on driving internal changes in tooling to improve developer satisfaction and productivity. The team listens to their customers, determines the most impactful opportunities and executes on delivering those changes. The team works technologies including modern Linux embedded C++, build systems, cloud backend systems, and web platforms.

About the role

You will be working on a software PAL version of the Roku OS which represents real hardware but facilities wider scale testing accessed via cloud hosting and web/API for internal users and Roku Partner development teams.

This is a very diverse role with exciting challenges and opportunities. One day you might be doing video decoding, or audio distribution, or tweaking docker, or testing app development or build tasks or cloud integration, or security or a ton of other things. Every day is going to be a different problem and an opportunity to really learn about a lot of new tech and help design the infrastructure of a pretty complex system.

What You’ll be doing

Focus on the Native Build of Roku OS, which operates without physical hardware - drive forward the development and continue to keep the platform current and meeting the needs of internal and external users - covers both hand-on development and working with other teams to support them.
Solve design problems in embedded software, application SDKs, networking, graphics, UIs, media and other areas across Advanced Engineering, always with an eye on the resource constraints of our players and TVs
Write efficient software that can be easily ported to new or existing platforms
