Sr Software Engineer, Ad experience platform

Position Summary 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. Thriving here means understanding those constraints deeply and building software that is fast, resilient, and consistent across the entire device ecosystem. 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. Role and Responsibilities Write efficient, clean, readable, fast, testable, and documented code. Prototype and develop consumer-facing services that will be displayed on millions of devices. Collaborate with internal and external teams (Product Managers, UX designers) and other Software Engineers to deliver a compelling, easy-to-use product for the end consumers. Collaborate with peers and leaders across various Samsung Ad sites to drive cross-site efforts to improve platform capabilities. Effectively communicate ideas to peers and distributed teams. Contribute towards building a system with a test‑driven development and Agile approach. Work with geographically distributed teams. Author technical proposals to improve software design and architecture. Qualifications Bachelor’s or master’s degree in computer science or a related field.

Familiarity with scaling patterns: caching, background jobs, rate limiting, performance tuning. Experience building JavaScript frameworks and libraries for consumer‑facing devices with low memory footprints, focusing on application performance. Experience building backend services based on microservice architecture. Strong architectural and design skills. Proficiency with version control systems (Git) and front‑end build tools (webpack, npm). Experience with performance optimization, responsive design, and cross‑browser compatibility.
