Software Development HCMC 1,001–5,000 employees Founded 2012 Privately Held

Zalo operates a multi-million-user messaging and video platform native to Vietnam, now pushing aggressively into creator monetization and AI-driven ads. The tech stack spans React/Node.js frontend to Kafka/Redis backend, with active adoption of Feast (ML feature store) and a leadership gap in AI and product strategy — suggesting a shift from core messaging toward machine learning and advertising optimization. Hiring velocity is accelerating across engineering and product, with 20 roles posted in the last 30 days and explicit focus on ad delivery performance and creator ecosystem expansion.
