Our AI doesn't just optimize—it delivers the measurable outcomes that matter most to our clients, giving them the competitive edge they need in a crowded marketplace. Ready to join the team that's defining the future of digital advertising? We operate at a large scale, processing 100+ billion events a day, at split-second latency, across 100+ million directly-measured destinations.   Our engineering organization in London builds and operates many of the critical components underpinning the Quantcast product, including: real-time distributed systems, audience modeling, delivery control systems, large-scale data infrastructure, integrations with partners in the adtech eco system, payments and revenue processing, artificial intelligence infrastructure, and more.   We’re actively looking for Software Engineers to join us on our mission.
