Senior Software Engineer, Roku TV

Teamwork Makes the Stream WorkRoku 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 TeamWhen you work at Roku, you work on a platform that real people use: 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 member of the Roku Products Engineering team, you will design and develop embedded software systems that enable us to build world-class products, with Roku "inside" as their OS. To make this possible, you will work on the Roku OS on new technologies and develop new features while keeping our existing code clean and performant. Additionally, you will work with product managers to accommodate shifting demands and schedules; collaborate cross-functionally with our QA and other development teams; and build solutions with external hardware component vendors.We are an AI-first engineering organization. We actively leverage AI tools and agentic workflows to amplify our velocity, quality, and innovation. We expect every engineer on this team to view AI as a core part of their daily workflow not an afterthought, and to continuously push the boundaries of what's possible with AI-assisted development.We value individuals who take pride in their ability to navigate ambiguity, collaborate, and partner with both internal and external teams, including those with demanding engineering standards and a passion for building the highest-performing, best-in-class consumer products. 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 things used by millions of people, if you want a tech culture that just works, you should reach out.How Will I Use AI at Roku?At Roku, we don't just use AI, we work with it. AI agents and smart tools help power drafts, analysis, and repetitive workflows, while our people bring direction, judgment, and accountability. We're looking for curious, adaptable builders who can show how they've used AI or automation to move faster, raise the bar, and scale their impact.We value your AI skills if you have built fluency across the agentic engineering toolchain - coding harnesses like Claude Code or Cursor, MCP servers, custom skills, or agent frameworks. And you can describe projects where you shipped real work with these tools. You know how to create and drive an agent, verify its output, and ramp on an unfamiliar codebase with an agent helping you.About the RoleWe are looking for a talented engineer to join our New Products Development Team working on the Roku TV program! You will be responsible for core tasks ranging from Roku OS feature development, SoC partner collaboration, third-party API integration, code maintenance, design scalability solutions to help onboard new factories, supporting our QA and Channel certification teams, and everything else involved in our end-to-end product development and release cycles. You will be expected to use AI coding tools daily to accelerate your work and elevate the quality of your output. To succeed in this challenging role, the following expertise is strongly preferred.What You'll Be DoingRoku OS feature development, leveraging AI tools to accelerate coding, debugging, and iterationCode maintenance and scalability solution design and developmentPartner with internal QA and development teamsSystem-on-a-Chip (SoC) integration and platform bring-upThird-party API integrationWorking end-to-end product development and release cyclesCritically evaluating AI-generated code for correctness, security, and performance in embedded contextsContributing to team AI productivity - sharing effective prompts, workflows, and tooling improvementsWe're Excited If You HaveAI-First Required QualificationsProven AI-assisted coding experience - Regular, hands-on use of AI coding tools (e.g., Claude, Copilot, Cursor, OpenCode) in real development work, with specific examples of AI tools used in production workflowsPrompt engineering and AI code review skills - Ability to write effective prompts, iterate on AI output, and critically evaluate AI-generated code for correctness, security, and performance; can identify hallucinations, subtle bugs, and security vulnerabilitiesAgentic coding tool proficiency - Hands-on experience with agentic coding harnesses (e.g., Claude Code, Cursor, Copilot, Codex) with specific examples of driving an agent through a non-trivial engineering task, verifying output, and recovering from agent errorsAI threat awareness - Understanding of how AI can be exploited (prompt injection, data leakage, etc.) and ability to code defensively against these risksBuilder mentality toward AI - Actively pushes AI boundaries, adapts quickly to new tools, and views AI as core to their workflow rather than optionalAI-First Preferred QualificationsPortfolio of projects where AI tools were central to the development processExperience shipping production features integrating LLMs, embeddings, or AI capabilitiesDeep embedded systems domain expertise combined with AI fluency to amplify output and velocityContributions to AI tooling or productivity - custom agents, internal tools, scripts, or workflows that accelerate team outputCore Engineering QualificationsBachelor's or master's degree in Computer Science, Computer Engineering, Electrical Engineering, or other relevant fields8+ years of relevant software development experience4+ years C/C++ coding experienceSystem-on-a-chip (SoC) development and integration preferredExperience developing/debugging on Linux or Android-based embedded platformsGood understanding of Linux system and kernel concepts, multithreading primitives, Linux tools, libraries, and open-source developmentExperience with streaming audio/video platforms, graphics, and industry standardsAbility to excel in a fast-paced engineering environmentAbility to communicate with candor and effectivenessExperience working collaboratively with cross-functional teams
