An Insider's view of Wish

How do you collaborate with other teams in the company?

As a designer at Wish, we primarily work cross-functionally with product managers and engineers to deliver creative solutions. However, it’s also important to include other teams to get better feedback and perspective. For example, I work with our customer support teams to gather user feedback and apply that directly to my design solutions.

How has your career grown since starting at the company?

My goal coming out of university was to learn how to scale the infrastructure of a growing company. Larger tech companies have mostly solved these scalability problems and Wish gave me the opportunity to solve tough problems hands on. Wish is now handling 100x the traffic since I joined and I'm still learning new things everyday.
