About Vui App
At Vui App, we’re building Vietnam’s first flexible benefits platform — where every data flow, every integration, and every line of logic directly impacts the experience of thousands of workers.
And you will be part of the team that makes this possible.
What You Will Do

2. Data Operations
Monitor dashboards, system logs, and sync jobs daily to ensure stable and reliable data operations.
Investigate data discrepancies (e.g., mismatched working hours) and identify the root cause; coordinate with the Dev team when issues come from the core system.
Conduct periodic data quality reviews and prepare operational reports for customers or internal teams.
3. Documentation \& Optimization
Write technical documentation: integration guidelines, data specifications, and internal SOPs.
Propose improvements to product features or operational workflows based on insights from real-world issues.
(Optional) Contribute to fixing minor bugs or optimizing sync logic if you’re confident in your coding ability.
