Core Delivery Products is the Ads pillar that builds the products that power the core capabilities of our ads system: from targeting, to bidding, optimization, and user quality. The team has a strong and long-standing track record of making critical contributions to company top line goals with most of Meta revenue flowing through these core systems, and our year on year improvements continuing to drive significant top-line impact. In EMEA, we have 3 complete sub-pillars operating with high autonomy: Targeting, Core Ads Quality, & Direct Response Optimization. All the sub-pillars are responsible for growing revenue, machine learning product solutions end to end, alongside the reliability and stability of these core products. All have their cross functional teams co-located with them.

Meta builds technologies that help people connect, find communities, and grow businesses. When Facebook launched in 2004, it changed the way people connect. Apps like Messenger, Instagram and WhatsApp further empowered billions around the world. Now, Meta is moving beyond 2D screens toward immersive experiences like augmented and virtual reality to help build the next evolution in social technology. People who choose to build their careers by building with us at Meta help shape a future that will take us beyond what digital connection makes possible today—beyond the constraints of screens, the limits of distance, and even the rules of physics.
