I craft designs that positively impact people.

Tina Hsieh,
Sr. Product/ UX Designer at Mozilla


I’m a Sr. product/ UX designer currently working at Mozilla. In my 6 years of experience, I have worked on a variety of products ranging from automobile HMI, connected device, desktop browser, websites, to mobile apps. Being a designer with an engineering background and experience in different fields of products makes me learn about the industry and design constraints with ease, which allows me to consider users more in my design process.

My design philosophy

I believe that “always learning from users” is the key to delivering meaningful designs to users. In my previous projects that targeted Indonesian vendors and Taiwanese seniors, I led the team through the entire user research process and concept validations which helped the team and I gained more empathy from the face-to-face activities into the designs we created.  

I also believe that designing good products isn’t the only way to create a positive impact on people. Therefore, I love sharing my design experiences through talks and blogs. I hope it can not only inspire more people, but also reduce their struggles in design.

What I do in my spare time

Outside of work, I find myself recharged when I continuously challenge myself like practicing new skateboard tricks 🛹, bodyboarding at dawn 🌊, decorating my house with seasonal flowers 🌷, and capturing beautiful moments while traveling 📷.
