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 

The Advanced Development team invents the next generation of intelligent, generative, and data-driven systems at Roku. We work ahead of production, building prototypes that evolve into the foundations of future Roku products - including LLM-powered analytics, internal automation platforms and creative tooling.  

You’ll join a small, high-ownership team working across UI, AI-assisted workflows, data discovery, and internal developer tools. It’s a fast-paced, exploratory environment with a mandate to turn promising ideas into working software that delivers measurable value. 

 

About the Role 

We’re looking for a front-end engineer to help build our next generation intelligent internal tools and data platforms. Your work will empower the organization to turn raw data into actionable intelligence through robust and secure internal tooling. 

In this role, you’ll design and build modern, responsive interfaces for internal applications that help teams retrieve, analyze, and visualize business data. You’ll work at the intersection of UX and AI, shaping how LLM-assisted systems present insights and recommendations to users in clear and trustworthy ways. Along the way, you’ll collaborate with experienced engineers and designers to build UI components for our internal tools ecosystem and translate complex backend logic into intuitive user experiences.

 

What You’ll Be Doing 

  • Build Data-Rich Interfaces: Develop dashboards, charts, tables, and interactive visualizations that make large or complex datasets easy to interpret and act on. 
  • Design Human-Centered AI Interfaces: Create front-end workflows that integrate LLMs, chatbots, and AI-generated insights—ensuring transparency, clarity, and user trust. 
  • Develop Robust Front-End Architecture: Implement reusable components, internal UI libraries, and data-driven widgets that support analytics, decision-support tools, and workflow automation. 
  • Collaborate Across Disciplines: Work closely with backend, analytics, and design teams to translate complex logic, schemas, and business rules into clear, intuitive UI. 
  • End-to-End Delivery: Participate in rapid prototyping, user testing, iteration cycles, and front-end performance tuning. 
  • Design for Clarity & Trust: Implement thoughtful guardrails and explainability features that help users understand how data was calculated or why an insight was surfaced. 
  • Engineering Best Practices: Contribute to code reviews, architecture discussions, and UI/UX standards for internal tools. 

 

We’re Excited if You Have 

  • 2–5 years of front-end engineering experience, with solid fundamentals in HTML, CSS, and JavaScript/TypeScript, and hands-on experience with at least one modern framework such as React, Vue, or Svelte. 
  • Experience building data-rich interfaces - including tables, charts, filters, and dashboard-style interactions - and familiarity with design systems or internal UI component libraries. 
  • Comfort working with SQL and understanding schemas, along with an interest in building tools that help non-technical users safely access and explore business data. 
  • Interest in AI-assisted UI design, including integrating LLMs, prompts, or agent-generated insights into product workflows—or eagerness to learn. 
  • Experience consuming REST APIs or internal services and translating backend logic into clean, understandable UI. 
  • Ability to prototype quickly and iterate based on feedback, turning user or analytical needs into polished front-end solutions. 
  • Familiarity with data tools or visualization libraries such as D3, Chart.js, Recharts, or similar technologies. 
  • A product-minded approach, comfortable turning ambiguous problem statements into coherent solutions and collaborating across backend engineering, UX, analytics, and product teams. 
  • Ability to thrive in fast-paced, exploratory environments where prototypes evolve quickly and requirements shift as we learn from users and the system.

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.
