Diana Mounter

I’m a designer with an interest in systems thinking, code as a material, and inclusive design. I work remotely for GitHub as their Head of Design. I live in Brooklyn, NY, with my husband and two cats.

Work

GitHub: Dec 2015 - present

As GitHub's Head of Design I lead a cross-functional team including Product Design, Customer Research, Brand and Marketing Design, Design Infrastructure, Design Engineering, and Design Operations. My team is responsible for the end-to-end user experience of GitHub's products, brand direction for key events such as GitHub Universe, and delivering compelling launch campaigns such as Copilot X.

Since joining GitHub in 2015, I led the Primer design systems team and developed Primer from a CSS framework to mature design system of components, documentation, and tooling. Under my leadership, the team also shipped a significant visual rededesign and the biggest changes to the repository homepage in 5+ years. In 2020, my team delivered one of GitHub's most highly requested features – Dark mode.

In the first half of 2022 we were in a hyper-growth phase and I grew the team by 42%, onboarding designers, researchers, design engineers, managers and directors across the organization. I've developed the team’s practices and processes, and built new specialist design teams such as growth design and accessibility design. Through my role leading design systems and now leading the Design Org, I've also been working to build a more inclusive design culture and experience for our customers.

Etsy: Dec 2013 - Dec 2015

Prior to joining GitHub, I spent several years at Etsy, where I worked on re-designing seller tools, developed the design onboarding process, taught new designers how to push code, and was part of a small team that built a new design system.

Talks

I speak at design and technology events across the U.S. and around the world. I am motivated by the opportunity to share my experiences and learnings with others and to help others grow in their careers. Many of my talks have been focused on design systems, but I also speak about leadership, design culture, and inclusive design.
