Full Job Description
About the team

Join the Home Screen team - the engineers behind Roku's home screen and Browse Surfaces, the experience that greets every Roku user when they turn on the TV. We ship to hundreds of millions of devices. Work spans SceneGraph / BrightScript UI, an evolving TypeScript SDK, and the cloud services that drive layout, content, and experiments. We move fast, own features end-to-end, and partner tightly with product, design, ML, ads, and cloud.
About the role

We're looking for a Senior Software Engineer who thrives across the full stack of the home screen: client UI frameworks, APIs, and cloud-backed experiences - and who treats agentic AI as a real engineering practice, not a buzzword. You'll ship user-facing surfaces, harden the services and contracts behind them, and build (or extend) agents, skills, and harnesses that make the team faster in production.

You do not need to be a firmware or OS kernel engineer. Deep C++ or low-level OS work is a plus if you have it; the day-to-day bar is modern full-stack delivery on a constrained TV platform, plus proven agentic fluency.

For California only - estimated annual base salary: $141,300 - $360,700. Compensation packages vary by candidate (skill set, certifications, location). Role is eligible for health insurance, equity awards, life insurance, disability benefits, parental leave, wellness benefits, and paid time off.
How you will use AI at Roku

At Roku, we don't just use AI - we work with it. Coding harnesses (Claude Code, Cursor, and similar), MCP servers, custom skills, and agent workflows are part of how this team ships. You should be able to drive an agent on an unfamiliar codebase, verify its output, and talk about what broke when you put multi-step agents on real systems.
What you will be doing
  • Design and ship home screen & Browse Surfaces features across SceneGraph / TypeScript UI and cloud-backed content and layout services
  • Own features end-to-end: API contracts, client integration, experimentation (A/B), rollout, and production health
  • Build and improve agentic tooling the team actually adopts - skills, harnesses, evals, triage/fix agents - not one-off demos
  • Drive performance, memory, and reliability where it matters for TV clients and the services behind them
  • Partner with UX, PM, ML, ads, and cloud engineering on AI-assisted and personalized experiences
  • Mentor engineers; raise the bar on design reviews, agent-assisted code review, and delivery discipline
We are excited if you have

Core (this is the bar)
  • 7+ years shipping production software, with real full stack ownership (UI + APIs/services), not frontend-only or backend-only
  • Strong TypeScript and/or JavaScript, plus comfort in at least one of: BrightScript / SceneGraph, React (or similar component UI), Python, or Go
  • Experience building cloud-integrated product surfaces (REST/GraphQL, event-driven updates, server-driven UI or remote config)
  • Evidence of shipped agentic work others use: multi-step agents, tool/MCP integrations, RAG or eval loops, coding agents in a real workflow - come ready to show what it does and what failed
  • Clear practice for staying accountable for code you did not hand-type (design-first, review gates, tests/evals)
  • Collaboration across product, design, and multiple eng partners; comfort with ambiguity and phased rollouts
  • Hybrid San Jose; strong written/async habits for US/UK collaboration

Strong pluses (not required)
  • C++, embedded, or consumer-electronics / TV SDK experience
  • Linux debugging, multi-threading, or constrained-device performance work
  • A/B / experimentation platforms, plugin or component-library architecture
  • Prior work on home screen, browse, recommendations, or large-scale consumer clients
How we interview

Working fluently with AI tools is an explicit expectation. The loop includes a hands-on exercise on an unfamiliar codebase using the tools you'd normally reach for. We're watching how you approach a new problem - not whether you've memorized an API.
Hybrid working

Teams generally work in the office Monday through Thursday. Fridays are generally flexible for remote work, except where a role or office requires five days on site.

What's Roku's approach to hybrid working?
