UX/UI Developer (AI Prototyping)

We are seeking a Senior UX/UI Developer to join a specialized digital studio focused on the future of AI-driven internal tools. In this role, you will bridge the gap between design and engineering by building interactive, high-fidelity prototypes that utilize LLMs and agentic UX patterns. You will not only build prototypes for research but also develop the actual tools-like Figma plugins-that help other designers work more efficiently.

• Partner with designers and researchers to rapidly prototype agentic and AI-powered UX flows (multi-turn, reasoning, orchestration) using Figma, Copilot Studio, and internal sandboxes.
• Build and iterate interactive prototypes suitable for research, demos, and engineering handoff.
• Develop reusable internal UX tooling such as Figma plugins and lightweight UX automation scripts (design critique helpers, pattern suggestions, weekly update summaries).
• Maintain a shared internal Agentic UX space that centralizes patterns, reusable prototypes, and research insights.
• Contribute documentation and reusable assets to the shared Agentic UX Platform to ensure knowledge transfer.
• Follow security and compliance requirements for internal tooling and data handling.

Skills

- Strong experience in data-driven software design and development

- Experience building functional design prototypes and internal AI-powered tools

- Experience with AI-assisted workflows and/or LLM APIs (Azure OpenAI preferred)

- Experience collaborating with designers and researchers in fast iteration cycles

- Strong communication, problem solving, and documentation skills

Education / Experience

- Bachelor's degree in a technical field such as Computer Science, Computer Engineering, HCI, or related field

- 8+ years experience in UI/UX engineering or UI/UX development

Bonus: Experience with Azure OpenAI, Figma plugin development, Copilot Studio, or AI-powered rapid prototyping tools

Portfolio Required: Must be able to demonstrate 2-3 coded projects involving AI or complex UX prototyping.
