Over the last few years, Duolingo has expanded beyond language learning into entirely new subjects: Math, Music, and Chess. These products reach millions of daily active users, are growing quickly, and represent a CEO-level bet that Duolingo can become a platform for learning anything. We're looking for a Senior Director of Engineering to co- lead our newest subjects, responsible for building and scaling products ranging from early stages through to some of the company’s fastest-growing initiatives. This is a role for a builder.

Drive operational excellence across Duolingo’s engineering org , including reliability, performance, developer productivity, and efficient execution at scale. Contribute to Duolingo’s engineering hiring bar and talent systems , playing a central role in hiring decisions, leveling, and organizational design to maintain a high-performance, high-density team. Lead an organization that moves quickly, runs high-quality experiments, and translates product insights into measurable business impact. Build and develop a strong leadership bench capable of bringing ambitious new products to market. ✅ You have... Experience leading consumer product engineering organizations (100+ engineers), ideally across multiple high growth product experiences. Product instincts and experience partnering closely with senior product leadership to define strategy, not just execute against it. A track record of driving measurable impact on business outcomes , including growing early product development through significant company scale. Experience building or scaling LLM-powered product features, with a strong interest in building engineering cultures that embrace AI-first ways of working. Deep experience building and scaling high-velocity, experiment-driven product organizations , leading through multiple layers of leadership (senior directors, directors, EMs).
