Pacing Service, which belongs to the Prospecting team, is an integral part of the Quantcast Ad serving mechanism, and manages delivery (impressions, spend etc.) for Ad campaigns. 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 growth levels - which are coming quickly considering the rate we scale our architecture every six months. We’re eradicating most of our vanilla single master/machine topologies, splitting data processing pipelines to work in multiple shards and applying queueing systems to handle hundreds of millions of events. This means getting up close and personal with cutting edge technologies like Kafka and Cassandra, and building next generation scalable, high performance fault-tolerant 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 the key-value distributed store using Keebler. If this sounds like you, join the team that’s building the next generation pacing services.
