Square's Icon System has over 1000 icons. Most of them are marketing icons built at 3 sizes: 80x80, 40x40, and 24x24. I built around 700 of our icons, taking over where our design director left off. All of them are built in Figma, meaning that they are easily accessible to both marketing and product designers. I then worked with our engineering team to implement all these icons into our manifest.
I also work with the Design Systems team to develop specialty icons like this special set which was custom made for Square's new hardware: Square Terminal.
