What we do

At The Trade Desk, Front-end Software Engineers deliver complex and data-rich UIs to our internal users and external clients. User experience can make or break our business, and it’s crucial that we deliver a simple interface to our powerful and sophisticated platform, as well as rich insights mined from the petabytes of data streaming through our pipelines.

The Front-End Fundamentals team owns the overall framework and high-level architecture patterns that our feature teams use to deliver powerful features to our users, from campaign creation and targeting to real-time performance monitoring and troubleshooting. Alongside our partners in product management, design, and UX research, we work up and down the stack to deliver world-class experiences.

Who you are:

We have a lot of fun together (especially on this team), but our culture is much deeper than that. Our UI engineers are passionate advocates for our users, both internal and external. We build trust by supporting each other generously; we approach problems with scrappy determination; and we pursue excellence unfailingly even when—especially when—it’s not the easy path. Oh, and we laugh a lot. We take the work seriously, but not ourselves.
