AI, a Redwood City, CA-based startup, is building the next-generation AI inference platform that accelerates the deployment of large language and multimodal models with unmatched performance and efficiency. Our infrastructure supports high-throughput, low-latency AI workloads for organizations worldwide. We are also integrated with the Hugging Face platform, allowing instant access to over 400,000 open-source models. We are on a mission to deliver the world’s best platform for generative and agentic AI.

We are seeking a frontend engineer with a passion for high-performance UI and AI applications. This role focuses on crafting scalable, accessible, and optimized interfaces that empower users to manage generative and agentic AI deployments. You will play a key role in shaping user experience across our developer dashboard, agent builder, and observability tools.

An ideal candidate thrives at the intersection of frontend engineering and AI. You are deeply comfortable with scalable component systems, accessibility standards, and modern Type Script-based architectures. You enjoy crafting elegant interfaces as much as working with agentic frameworks and AI-native interaction patterns.

• Strong understanding of monorepo maintenance, code reuse patterns, and scalable UI systems
• Familiarity with data visualization frameworks, real-time APIs, and frontend performance monitoring tools

• Experience working with LLMs, prompt-driven UIs, or agentic orchestration frameworks
• Background in frontend systems for developer tools or AI platforms
• Strong documentation and writing skills (for internal tools or user education)
• Passion for design systems, usability, and performance optimization
• Have built developer-facing products or technical UIs
• Understanding of AI agent architectures or multimodal UI patterns
