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 Team
At Roku, the Device Monetization and Themed Experiences (DMTE) team, a part of the Advertising organization, is where the magic behind the scenes happens. We’re the engineers who build the high-performance graphics and UI foundations that power the FRAME engine — the core technology enabling Roku’s smooth, responsive, and visually rich experiences on millions of devices worldwide. Our work lives in the middleware and UI layers, and its impact is felt every time a user navigates a menu, enjoys an animated ad, or is wowed by the bespoke experience built to market the latest TV show or Movies. We thrive on solving the toughest technical challenges — from optimizing UI rendering to fine-tuning memory usage — using BrightScript (a JavaScript-like language) to deliver rock-solid, high-performance solutions. We work in a collaborative, high-trust environment where great ideas can come from anywhere, partnering closely with firmware, UI, and product teams to ensure our platform is lightning fast, reliable, and ready for the next generation of streaming innovation. If you love building the invisible foundations that make great user experiences possible, this is the team for you.
About the Role
What You’ll Be Doing
- Apply strong software engineering principles to design, build, and ship reliable, performant systems at scale
- Bring rigorous software engineering practices — clean architecture, testing, code review – to building systems that are reliable and performant at scale
- Apply sound software engineering fundamentals (system design, testing, code review) to ship reliable, performant systems at scale
- We don’t train models, we don’t ‘fine-tune’ LLMs; We build automated agentic processes
- Design, build, and deploy agentic AI systems that autonomously generate, test, and optimize BrightScript/TypeScript code and UI experiences for the FRAME engine
- Architect multi-agent workflows (planning, tool-use, retrieval, execution, validation) that accelerate development and reduce manual engineering effort across the team
- Develop AI-powered automation that understands the constraints of embedded C++ environments and produces performance-safe, memory-efficient outputs
- Build and maintain evaluation frameworks to measure agent reliability, accuracy, and performance in production-critical contexts
- Collaborate with cross-functional teams (firmware, UI, product) to identify high-impact opportunities for AI-driven automation and intelligent tooling
- Stay at the forefront of agentic AI research — including LLM orchestration, RAG, function calling, and autonomous code generation — and bring those advances into our platform
- Mentor engineers across the team on AI-first development practices and help establish best practices for human-agent collaboration
We’re Excited if you Have
- Proven experience building agentic AI systems that generate, optimize, and deliver scalable applications in production environments
- Strong software engineering foundation with a track record of shipping reliable, performant systems at scale
- Deep familiarity with modern LLM orchestration tools, prompt engineering techniques, and AI/ML frameworks
- Experience with retrieval-augmented generation (RAG), function/tool calling, and evaluation-driven development for AI agents
- A builder’s mentality — you don’t just use AI tools, you create autonomous systems that multiply the impact of entire teams
- Proficiency in TypeScript (or similar languages) and Python for agent development, scripting, and pipeline automation
- A software engineer’s instinct for reliability, testability, and clean architecture — applied to the unique challenges of non-deterministic AI systems
- Excellent technical communication, root cause analysis abilities, and a proactive mindset with passion for fast iteration

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.
