At Quantcast, we’re redefining what’s possible in digital advertising. As a global Demand Side Platform (DSP) powered by AI, we help marketers connect with the right audiences and deliver measurable results across the Open Web. Our foundation is built on cutting-edge measurement and consumer analytics, giving our clients the tools they need to drive success in an ever-evolving digital landscape.
Since our start in 2006, we’ve pioneered industry firsts—from launching the original measurement platform for digital publishers to introducing the first AI-driven DSP. If you’re ready to be part of a dynamic, forward-thinking team that thrives on creating transformative solutions, Quantcast is the perfect place to grow your career.
At Quantcast, we use technology to help brands and publishers understand, reach and influence the constantly-changing behaviors of consumers. The Real-Time Bidding (RTB) 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.
As a Senior Software Engineer with a focus on Platform Reliability, you care about the health and maintainability of our systems and the velocity of the engineering teams. You write code, and design systems, build out proof of concepts, and compare and contrast technology alternatives that improve systems and automation throughout our products and tech stack. Working side-by-side with engineers you will build and operate real-time high-scalable systems.
