At Quantcast, we use technology to help brands and publishers understand, reach and influence the constantly-changing behaviors of consumers. The Real-time Bidding Platform owns and operates the large scale distributed stack which allocates millions of dollars of advertising budget to billions of bid opportunities streaming into the system. If you’re interested in working on these critical, fast, large scale distributed systems then we’d like to meet.

Working side-by-side with engineers and modeling scientists you will build and operate intelligent bidding, optimization, prediction and control systems that power different parts of this stack. You’ll lead projects to optimize the throughout of the stack while reducing costs and growing advertising performance. You’ll drive design and implementation of new products for clients that’ll involve multiple teams and services.
