Senior Software Engineer, Cross Platform Devices

With more than 85 million people using our products globally, we've become well-known for products that "just work" right out of the box and integrate almost by magic. That doesn't happen by accident, which is why we are committed to making sure our products aren't just intuitive; they're obvious. Our goal is to help people find what they want and make it easier for people to stream. We accomplish this using state-of-the-art technology and engineering to make it happen, considering the customer as the center of all that we do., * Own end-to-end delivery of complex, multi-release UI initiatives, from requirements and technical strategy through implementation, instrumentation, launch, and post-launch optimization.

• Make deep contributions across our stack: C++ for embedded/UI systems, BrightScript for app/channel surfaces, and TypeScript for developer tooling and UI apps; proactively improve APIs, test coverage, and observability.
• Define and implement performance architectures for rendering, layout, and animation; establish metrics, profiling methods, and regression gates for startup time, frame pacing, memory, and power.
• Mentor and level up engineers via design reviews, code reviews, pairing, and technical guidance; elevate engineering standards, documentation, and operational excellence across Cambridge and partner sites
• Influence roadmap and sequencing with data: design experiments, analyze telemetry, and steer fast iterations that measurably improve UX quality and reliability.
• Lead incident response and root-cause analysis for high-visibility UI issues; drive long-term fixes that harden systems and reduce recurrence.

Do you have experience in UI?, Do you have a Master's degree?, We are looking for a Senior Software Engineer to focus on developing core features for the Roku platform UI. We are looking for someone with experience building high-performing applications and SDK components who wants to code on a wildly popular consumer electronics platform. This is an excellent role for a senior professional who enjoys a high level of visibility, thrives on having a critical business impact, and is excited to work on a component that touches almost everything streamed on the Roku platform., * 5+ years building production UI or UI-adjacent systems with advanced C++ on embedded/consumer devices; demonstrated leadership owning ambiguous problem spaces and delivering 0 1 as well as 1 N evolutions.

• Extensive programming experience with C++ and Embedded Linux or Native Application development; in-depth understanding of Linux (tools, libraries, build systems) and open-source development workflows.
• Demonstrated leadership across C++, BrightScript, and TypeScript, including architectural design, API definition, and high-quality implementation spanning firmware-adjacent and app/tooling layers.
• Proficiency with AI-assisted programming (e.g., code generation, review, test scaffolding) applied responsibly to improve developer velocity, quality, and maintainability.
• Deep expertise in UI performance engineering: rendering pipelines, layout/animation systems, memory/CPU profiling, frame pacing, and low-latency optimizations on constrained hardware.
• Strong memory management and multi-threaded development skills, with practical experience in synchronization, contention reduction, and concurrency debugging.
• Experience with OpenGL and DirectFB for graphics pipelines and rendering on embedded Linux targets.
• Experience building or evolving UI frameworks, reusable component libraries, SDKs, and developer tools used by multiple teams, with attention to API ergonomics, backward compatibility, and maintainability.
• Embedded and consumer electronics experience, ideally shipping features across diverse hardware configurations and markets.
• Ability to estimate software tasks accurately, manage dependencies, and deliver to schedule in fast-moving environments.
• Proven mentorship and technical leadership: facilitating design reviews, leading cross-functional discussions, aligning stakeholders, and guiding engineers to deliver high-impact outcomes.
• Excellent root-cause analysis and cross-layer debugging skills; you consistently use telemetry, profiling, and controlled experiments to isolate issues and drive robust fixes.
• Strong written and verbal communication; able to represent the team in design/product reviews, articulate trade-offs, and drive decisions that improve user experience at scale.
• Bachelor's and/or master's degree in Computer Science or equivalent experience.

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., This team spends most of its time working on customer focused features that improve the user experience, from cross-platform device experiences, TV & Player centric UI, and IoT integration with Roku OS. Our product 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, QA, 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. We are the pragmatic dreamers inventing and re-inventing the world of streaming media., Roku fosters an inclusive and collaborative environment where teams work in the office Monday through Thursday. Fridays are flexible for remote work except for employees whose roles are required to be in the office five days a week or employees who are in offices with a five day in office policy., 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.
