VNPT is Vietnam's largest telecommunications provider, operating 20M+ mobile subscribers, 11M fixed broadband, and 10M fixed-line customers across 63 provinces. The tech stack spans legacy telecom infrastructure (Oracle, SQL Server, Hadoop, Cassandra) with emerging data-layer adoption (Apache Hudi, Iceberg, Delta Lake), signaling a shift toward real-time analytics. Hiring remains junior-heavy (28 junior vs. 4 senior roles) and concentrated in engineering and data, while security pain points dominate the project backlog—network incident response, vulnerability management, and compliance are outpacing feature velocity.
