Director of Engineering - Business Messaging Optimization

Meta's Business Messaging team helps businesses meaningfully engage their customers through messaging on WhatsApp, Messenger, and beyond. Marketing messages are one of the fastest-growing parts of Meta's business: businesses use them to re-engage the customers who opted in to hear from them, through the WhatsApp Business Platform APIs, Ads Manager, and Meta's own business tools. We are looking for a Director of Engineering to lead Marketing Messages Optimization: the end-to-end delivery funnel behind every marketing message. This org owns signals, ranking, auction and pricing, and delivery infrastructure. It decides which message reaches which person, when, how often, and at what price, balancing value for businesses with a high-quality experience for people. The role combines large-scale ads ranking and auction systems with the unique constraints of a messaging surface: a limited, opted-in audience, strong privacy commitments, and a high bar for user experience. You will lead a multi-team organization of engineering managers and senior engineers, set multi-year technical strategy, and partner closely with Ads, Business Agent, WhatsApp teams as well as across several functions including data science, product, and privacy across Meta. This is a high-impact, revenue-critical role at the intersection of monetization and messaging.
