VNG is hiring: Software Engineer - Bank Solutions (Java), Zalopay (Ho Chi Minh City)

The role

Bank Solutions is the Zalopay team that connects the e-wallet to banks and other financial institutions: account linking, top-ups, withdrawals and transfers. Its systems carry millions of real-time transactions a day, so reliability and security come first. Despite the "(Java)" in the title, the job is full-stack: you would design and build high-traffic backend services, mostly in Java with some Golang, build the screens users see, write unit tests on both sides, chase down problems anywhere in the stack and keep the system documentation current.

What they ask for

• 2+ years as a full-stack engineer on large, enterprise-style systems
• Strong Java 8+ with Spring Boot 2+, and experience building and integrating APIs
• Relational databases such as MySQL or Oracle plus Redis; event-driven systems with Kafka or RabbitMQ
• Solid OOP and design patterns; Docker, Kubernetes, networking and CI/CD
• Basic AI knowledge and everyday use of AI coding tools

Nice to have

• Golang
• Frontend work in ReactJS
• Scrum or Kanban
• A background in e-wallets, payments or banking, which the team values highly

Good to know

• Location: Ho Chi Minh City, in Vietnam.
• Job code 26-PFT-4049 (listing 6859 on VNG's careers site), first seen there on 6 November 2026 and open that day.

How the interview usually goes

VNG's engineering hiring usually starts with a CV screen and a short call, then one or two technical interviews on your main language, data structures, algorithms and backend design; some teams add a written test. For a payments team, expect questions about transactions, data consistency and what to do when a partner system fails. A final conversation with the team lead or manager is common.
