UI architect – What does that mean?

UI Architect required – The job opening caught my attention. I was a bit curious to understand what UI Architect really means and what they do? I know Solution Architect, Technical Architect, Principal Architect, but UI Architect was a very new term to me.

For most of the people, UI is restricted to HTML, CSS, few designing tools, graphics, and animation. It feels like with few colors, fonts, and pictures are all required to define perfect User Interface. We now have buzzwords like UX (User Experience), UI Designer etc. but then why this new role is required?
