• Hands-on experience with TypeScript, React, and Tailwind CSS.

• Experience developing, documenting, or evolving design systems for complex applications.

• A track record building workflow-driven interfaces with human review, exception handling, or approval steps.

• Practical experience with AI, machine learning, or LLM product features, and the ability to design clear, trustworthy user experiences.

• Experience conducting user research and usability testing to inform product decisions.
