AdGear focuses on enabling brands to connect with Samsung TV audiences as they are exposed to digital media across all devices. Being part of an international company such as Samsung and doing business around the world means that we get to work on big complex projects with stakeholders and teams located around the globe. 


Samsung has developed a proprietary ad platform that leverages unique first-party TV data to help brands connect to their audience as they explore content across desktop, mobile, tablets and our SMART TVs. The Samsung Ad Platform delivers high-quality audience targeting powered by three key components: first-party audience data at scale, data science, and brand-safe cross-device ad inventory.


Senior Software Engineer (Backend)


Why work in the Ads business?


Let’s face it, the ad industry doesn’t have the best of reputation. It is associated with spam email and annoying 5 seconds delay before you can watch your videos. But let’s face it, Ads are what is paying for all the free videos you are watching and your free social media accounts. Nothing is really free in this world. Why don’t you join a team that works hard to make ads work, respects personal privacy, limits exposure to the same ads, and follows regulations? In a world of bad pun and annoying jingles, AdGear is a good citizen. It also helps that the tech we’re using to build our system is cool.


About Campaign Management


Our group is responsible for delivering ads that are most appropriate for the end-user. We handle ~1,000,000 requests per second. We have a maximum of 100ms to parse an ad bid request, query our databases to find the most appropriate ad for that end-user, decide on our bid price, and respond. With an inventory of ~10,000 ads and campaigns, we need the best mind to optimize this bidding process.


Are you up to the challenge?
