Senior Front End Engineer (Agentic AI)

Join Roku as a Senior Front End Engineer in the DMTE team, where you'll embed intelligent, autonomous AI capabilities into our platform. You'll design and deploy agentic AI systems that optimize our development and delivery pipelines, and collaborate with cross-functional teams to identify high-impact opportunities for AI-driven automation. This role requires a strong software engineering foundation, proficiency in TypeScript and Python, and experience building agentic AI systems. Enjoy benefits such as medical, wellness, and financial benefits, unlimited paid time off, and work from home opportunities.

• Design 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.
• Collaborate with cross-functional teams (firmware, UI, product) to identify high-impact opportunities for AI-driven automation and intelligent tooling.
• 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
• A builder's mentality — you don't just use AI tools, you create autonomous systems that multiply the impact of entire teams
• Excellent technical communication, root cause analysis abilities, and a proactive mindset with passion for fast iteration
• Experience with retrieval-augmented generation (RAG), function/tool calling, and evaluation-driven development for AI agents
• Strong software engineering foundation with a track record of shipping reliable, performant systems at scale
• A software engineer's instinct for reliability, testability, and clean architecture — applied to the unique challenges of non-deterministic AI systems
• Proficiency in TypeScript (or similar languages) and Python for agent development, scripting, and pipeline automation
• Deep familiarity with modern LLM orchestration tools, prompt engineering techniques, and AI/ML frameworks
• Proven experience building agentic AI systems that generate, optimize, and deliver scalable applications in production environments
