Head of Marketing

Langaku’s Head of Marketing leads growth for its manga-based English-learning app, owning the path from user acquisition to monetization. The role sets growth direction and connects marketing with product development, working with product managers, engineers, and designers. The work includes analyzing user behavior and funnel data to find bottlenecks in acquisition, onboarding, retention, and payment; defining KPI trees and monitoring; and prioritizing actions by return. The lead drives experiments from hypotheses and A/B tests through measurement and implementation, plans in-app campaigns and push/email CRM, and directs digital advertising and ASO. Investment decisions consider CAC, LTV, retention, monetization, incremental impact, and brand lift. Candidates need approximately five years or more in growth or marketing for B2C web/app services, ownership from KPI design and budget management through execution and measurement, and data-led funnel or cohort analysis. They also need experience delivering product improvements and working in at least one of digital advertising, ASO, or CRM, plus LTV-focused growth experience and a deep understanding of manga culture.
