Senior Software Engineer

Online Advertising is one of the fastest growing businesses on the Internet today, with about $70 billion of a $600 billion advertising market already online. Search engines, web publishers, major ad networks, and ad exchanges are now serving billions of ad impressions per day and generating terabytes of user events data every day. The rapid growth of online advertising has created enormous opportunities as well as technical challenges that demand computationally intelligence and scalable algorithms. Eventually Computational Advertising has emerged as a new interdisciplinary field that involves information retrieval, data mining, machine learning, statistical modeling, optimization, linear algebra, and micro-economics, to solve challenging problems that arise in online advertising.    

Ads Frontdoor is at the core of this effort, working on large distributed systems with low latency and high throughput. Today, we design, develop, and operate a global ads marketplace that has a double-digit annual growth rate. This is a self-motivated and results driven environment that will unleash your potential. As a Senior Software Engineer, you would help build highly scalable, highly performant services which host state-of-the-art machine learning models. Your work will touch many components of our stack.
