AI Experience (Required): Hands-on experience across two dimensions — (1) designing and building AI-first, user-facing product experiences (e.g., generative or LLM-powered interfaces shipped to real users), and (2) using LLM-powered coding agents such as Claude Code , Codex , and other AI coding assistants to accelerate the SDLC and improve code quality. UI Architecture & Expertise (Required): Deep, hands-on expertise in ReactJS, TypeScript, and modern front-end engineering, paired with a proven track record of setting and driving front-end architectural vision — making the architecture decisions behind scalable, maintainable, high-performance UI systems.
