Sr Software Engineer, Ad experience platform

Position Summary

About the team

The Ad Experience team builds the products that greet every Samsung user the moment they turn on their TV - including Samsung''s home screen and the TV Plus app. Our work ships to hundreds of millions of devices worldwide.

We build Smart TV applications on the Samsung Tizen platform, where performance isn''t optional. These apps run on web-based runtimes with tight memory budgets, constrained CPUs, and hardware that spans a wide range of model years and price points.

Engineers on this team own features end-to-end - from the OS platform layer through the TV UI to cloud integration with DSPs and Ad Exchange. We move fast, hold a high bar, and work closely with product, design, and cross-functional engineering partners to ship ambitious ideas at scale.
