Summary
Jonathan Zempel is a Senior Principal Software Engineer and long-time design systems practitioner based in Chapel Hill, NC, with 15 years of focused experience shaping resource-oriented design and pixel-perfect UIs. At Zendesk he has evolved from Director of Design Systems into a senior principal role, blending creative leadership with deep engineering rigor to scale consistent interfaces and APIs across large products. His background spans startups and enterprise—building internet-scale social health apps at Genomera, fashion-forward UIs at Pickwick & Weller, and enterprise eLearning systems at IBM and Macromedia—so he bridges product sensibility with robust architecture. Known as a "pixel geek" on GitHub, he pairs an attention to visual detail with pragmatic system design, often favoring opinionated, service-oriented patterns that make developer experience a first-class concern.
