Software Engineering Internship Program (Summer 2027)

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. 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 Join Roku as an Engineering Intern, where your passion for technology and creativity will drive our success. We offer a paid 12-week internship, running from June to early September 2027. As an Engineering Intern, you’ll be assigned a scoped project with one of our engineering teams, working on real Roku products and platforms. We’ll match you to the team that best fits your skills and interests, so you may work on anything from user interfaces and embedded or platform software to automation, developer tooling and AI-powered workflows. Our teams work across a variety of languages and technologies and embrace GenAI-assisted development to boost productivity and quality. What you’ll be doing • Own a well-defined project that contributes to the success of your team. • Write clean, well-tested, maintainable code using modern languages, tools and engineering practices. • Debug, test and profile your work, and document it so others can build on it. • Collaborate with engineers and mentors, take part in code reviews, and share your progress and learnings. Apply if • You are a penultimate-year student, or a final-year student planning to go on to a one-year master’s course. • You hold a permanent right to work in the UK. Unfortunately, we are unable to consider candidates on a student visa. • You are available for full-time work for the whole 12-week program, from June to early September in Cambridge. • You are keen to work with AI technologies and have previous experience building AI agents and automated workflows. We’re excited if you have • Currently enrolled in a degree program in Computer Science, Engineering or a related field. • Proficiency in one or more of C, C++, Python, JavaScript, TypeScript or similar languages, ideally with projects, open source or hackathon work beyond your coursework. • A solid grounding in computer science fundamentals such as data structures, algorithms, and operating systems or networking concepts. • Hands-on experience using GenAI tools in your coursework, projects or personal work. • Strong problem-solving and technical communication abilities. • Proactive mindset with passion for continuous learning and fast iteration. 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. You know how to drive an agent, verify its output, and ramp on an unfamiliar codebase with an agent helping you. What's Roku's approach to hybrid working? Roku fosters an inclusive and collaborative environment where teams generally work in the office Monday through Thursday. Fridays are generally flexible for remote work, except for employees whose specific roles or assigned offic
