The runtime execution of advertising campaigns is a key capability that manages how we spend budget, impressions, etc. in a real time bidding environment. We want to build the foundation of loosely coupled, highly cohesive service-oriented pacing service architecture that’s going to propel us into the next level as we grow rapidly. At Quantcast, full-stack engineers work in all aspects of agile application development, from DB schema design through backend business logic to advanced Javascript on the frontend. This means getting up close and personal with cutting edge technologies like Kafka, Cassandra, AngularJS, React, jQuery, and building next generation scalable, high performance fault-tolerant end to end systems. You might have used one of our open source projects like QFS. Or maybe you’ve read our blog post on how we manage key-value distributed store using Keebler. If this looks interesting to you, join the team that is building the next generation of advertising runtime execution service.
