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. What does the team work on? 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 AD Display — 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. What is the role? As a Senior Agentic AI Engineer in the DMTE team, you'll be the driving force behind embedding intelligent, autonomous AI capabilities into Roku's platform — reimagining how our systems create, optimize, and deliver experiences to tens of millions of devices. Rather than building UI features directly, you'll design and deploy agentic AI systems that reason, plan, and act across our development and delivery pipelines — from automating the generation of themed experiences to enabling self-optimizing rendering workflows within the AD Display. You'll leverage your years of experience in software engineering and building world class UI to build AI agents that understand the constraints of embedded, performance-critical systems and operate effectively within them. This is a role for engineers who think in terms of autonomous systems, multi-step reasoning, and tool-use architectures — and who want to fundamentally reshape how a streaming platform is built, maintained, and evolved. 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 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 drive an agent, verify its output, and ramp on an unfamiliar codebase with an agent helping you. What are the responsibilities of the role? 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 What experience would help someone be successful in the role at Roku?

We offer you the opportunity to delight millions of TV streamers around the world while gaining meaningful experience across a variety of disciplines. What does the team work on? Roku is the No. 1 TV streaming platform in the US, Canada and Mexico, with more than 100 million active accounts. Every ad impression across that platform has to be cleared and priced in real time — that is what the Ads Auctions and Marketplace Optimization team does. We build the auction mechanics, the pricing and pacing logic, and the low-latency systems that run them, balancing outcomes for advertisers, publishers, viewers, and Roku on every request. We are growing the team in Cambridge, which is becoming its largest hub, alongside colleagues in Amsterdam, Austin, San Jose, Ukraine and Uruguay — so you would be shaping how the UK side of this team works rather than inheriting it. What is the role? You will build the systems that apply mathematical and algorithmic rigour to optimise across multiple objectives, deciding which ads get served, in which placements, and when. The work spans auction mechanics, optimisation, the output of predictive ML models, and the real-time infrastructure underneath, mostly in Java on the JVM. It is hands-on and senior in scope: expect to move between whiteboard-level design and production code in the same week, and to own problems from framing through rollout. You will work directly with the hiring manager and a small group of senior engineers, in codebases shared with other ads engineers, on problems where your decisions are visible in revenue. You will optimise for second-order effects in a marketplace where participants react to each other, and to us, in real time. We are looking for people who are enthusiastic about solving these kinds of problems. How will I use AI at Roku? At Roku, we don't just use AI, we work with it.

What are the responsibilities of the role? Design and build components of Roku's real-time ad auction and marketplace systems Own the multi-objective optimisation at the core of the auction, balancing what advertisers, publishers, viewers, and Roku each want from the same impression Own development work end to end, from framing the problem through production rollout Build and operate JVM services where latency and reliability are product requirements, not stretch goals Use probability, statistics and experimentation to test changes before and after launch Work with AI tooling as a normal part of how you design, build, test and review Explain technical trade-offs clearly to engineering and cross-functional partners What experience would help someone be successful in this role at Roku? Around six or more years building production software, with strong systems judgement Production experience in Java or another JVM language, or depth in a comparable statically typed language such as C#, C++ or Go, and the appetite to ramp on Java Comfort designing and operating distributed systems at scale and low latency A solid grounding in maths, algorithms, probability and statistics as applied to real systems Demonstrated AI and agentic-tooling fluency, as described above Ad tech, auctions or marketplace experience is preferred, and we move quickly for candidates who have it Comparable experience on mathematically rigorous or optimisation-heavy problems in another domain is an acceptable alternative #LI-MS3 What's Roku's approach to hybrid working?
