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 role

When you work at Roku, you work on a platform that is used by real people: You can show off the fruits of your labor to your family and friends and see it in your favorite stores’ electronics departments.

As a senior member of the Roku Core OS team, you will be part of a team responsible for designing and building the core/system parts of Roku OS. We are looking for a senior software engineer with extensive experience in embedded Linux development and integration.

Roku has a long track record of building successful products around value SoCs, relying on our talented software engineers to make the most of limited resources.

We aren’t kidding that Roku is a place where no one is a bystander. If you want to work on a team where you will be surrounded by the best talent building products used by millions of people, if you want a tech culture that just works, you should reach out. Come join us to build the next generation of great streaming players and TVs at a low cost for our customers.

What you’ll be doing
  • Design and develop OS features in a multi-process environment that are fast, efficient and maximize platform flexibility
  • Demonstrate excellence in C++ development and deliver high-performance, ultra-reliable software - optimisation, performance & memory.
  • Implement features with the abstractions necessary to run on a variety of hardware
  • Design for performance and ensure that your code is fast and resource efficient
  • Demonstrate the ability to dig-deep to find solutions to new and challenging problems
We’re Excited If You Have
  • 5+ years of experience developing Linux-based consumer electronic products
  • Excellent modern C++ programming skills
  • Proven track record of success with embedded system development projects
  • Experience in API design and developing portable code
  • Deep understanding of multi-threaded development and concurrency management
  • Experience with Linux IPC mechanisms
  • Ability to architect, implement, and test systems for performance
  • AI literacy and curiosity. You have either: 1) tried Gen AI in your previous work or outside of work or 2) are curious about Gen AI and have explored it.
  • Bachelor’s or Master’s in Computer Science, or equivalent engineering experience
Benefits

Roku is committed to offering a diverse range of benefits as part of our compensation package to support our employees and their families. Our comprehensive benefits include global access to mental health and financial wellness support and resources. Local benefits include statutory and voluntary benefits which may include healthcare (medical, dental, and vision), life, accident, disability, commuter, and retirement options (401(k)/pension). Our employees can take time off work for vacation and other personal reasons to balance their evolving work and life needs. It's important to note that not every benefit is available in all locations or for every role. For details specific to your location, please consult with your recruiter.

The Roku Culture

Roku is a great place for people who want to work in a fast-paced environment where everyone is focused on the company's success rather than their own. We try to surround ourselves with people who are great at their jobs, who are easy to work with, and who keep their egos in check. We appreciate a sense of humor. We believe a fewer number of very talented folks can do more for less cost than a larger number of less talented teams. We're independent thinkers with big ideas who act boldly, move fast and accomplish extraordinary things through collaboration and trust. In short, at Roku you'll be part of a company that's changing how the world watches TV.

We have a unique culture that we are proud of. We think of ourselves primarily as problem-solvers, which itself is a two-part idea. We come up with the solution, but the solution isn't real until it is built and delivered to the customer. That penchant for action gives us a pragmatic approach to innovation, one that has served us well since 2002.
