Software Engineer (Embedded UI, C++) in Cambridge

Teamwork makes the stream work. 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.

About the team: This team spends most of its time building and improving the UI framework and components that power Roku user experiences. Our roadmap helps us accelerate our growth and scale, putting surprising new features into the hands of tens of millions of Roku users worldwide. Our developers and engineers are owners. They are motivated from within, finding and taking on a feature or project simply because that problem needs to be solved and shipped. But that individual must work together with different engineering teams, UI design, product teams, and business leadership to make things happen, which means that engineers succeed here because they can maintain that independent spirit and motivation within a deeply collaborative environment.

About the role: Roku pioneered streaming to the TV and continues to innovate and lead the industry. While we are well-positioned to help shape the future of television and streaming media worldwide, continued success stems from experienced software engineers like you developing core features for the Roku platform. Our new Software Engineer, UI Infrastructure will be contributing extensively to our embedded UI framework development. You will be working closely with system architects to develop new features or extend current features to improve system stability and performance. You will also be engaged in developing tools which can help the larger development community within Roku. A proven track record of shipping high-quality software on embedded platforms is essential.

What You'll Be Doing:

• Building and maintaining tooling to improve the quality and consistency of data collected from Roku OS logging.
• Developing and evolving offline pipelines that process logs to support initiatives like pre-merge validation in Firmware CI and automated data contract generation.
• Writing and reviewing C++ changes in embedded codebases to ensure logging is accurate, reliable, and usable downstream.
• Creating Python-based tooling and automation (non-embedded) to extract, analyze, and validate log usage across large codebases.
• Partnering with engineers across UI infrastructure, firmware, and CI to integrate tooling into developer workflows and keep it production-ready.
• Troubleshooting issues across tooling, pipelines, and source instrumentation, balancing correctness, maintainability, and scalability.
• Using agentic coding to accelerate feature development and testing.

We Are Excited If You Have:

• 3-5+ years of relevant software development experience.
• Proficiency in modern C++ with the ability to read, debug, and extend embedded/firmware codebases.
• Strong Python experience for building developer tooling, automation, and offline data-processing workflows (e.g., log analysis and data quality improvements).
• Experience building or improving CI pipelines (including validation and quality gates) to support reliable releases.
• Familiarity with logging/telemetry concepts and an interest in improving data quality from code to downstream consumers.
• Working knowledge of core systems concepts (memory, threading/concurrency, and debugging) and the ability to apply them when investigating issues.
• Experience designing pragmatic internal tools or APIs, with an understanding of trade-offs and maintainability.
• Strong communication skills and a collaborative mindset, as this role partners closely with engineers across UI infrastructure and adjacent teams.
• Built JavaScript/TypeScript frameworks or worked on JS virtual machines and runtimes.
