Job summary

Roku is seeking a Senior Agentic AI Engineer to embed intelligent AI capabilities into its platform. You will design autonomous AI agents, reason and plan across pipelines, and deliver efficient, memory-conscious code for embedded environments.

Join the DMTE team to push the boundaries of AI-driven automation for streaming devices worldwide. Prepare to collaborate with firmware, UI, and product teams, leveraging BrightScript and TypeScript to build scalable solutions.

Qualifications

• 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.

Responsibilities

• 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.
• 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.
