Klook operates a mobile-first marketplace connecting travelers with local experiences across Asia Pacific. The tech stack reveals a data-intensive, AI-forward operation: Google Cloud infrastructure (BigQuery, Vertex AI, Dataflow) paired with streaming (Kafka, Apache Flink) and a Lakehouse architecture, now adopting LLMs (ChatGPT, Gemini) and RAG patterns. Hiring is heavily skewed toward marketing and sales (162 of 297 roles), with active work on booking conversion, demand forecasting, and inventory optimization—typical friction points for high-volume marketplace operations.
