Position

Creator applications generate and serve banners of different formats, from dynamically optimized HTML markup to real-time image and video rendering. Each display embeds multiple assets that must be built and optimized in real-time: dynamic HTML markup, post-processed JS code, animations, resized images, videos, etc. These components must be designed to run on multiple devices and browser with tight performance constraints. To reach this goal we develop an extensive set of atomic visual components to build state-of-the-art creatives for our thousands of clients, and monitor them in real time through client-side instrumentation.

As a software engineer working on these components you will:

• Deploy code to produce user-facing dynamic contents in real-time, displayed to billions of internet users every day
• Support new products by designing new components to enhance our creative offer (animations, images, videos...)
• Ensure uniform level of quality accross browsers and mobile devices
• Constantly improve visual rendering and performance of our banners
