QA Engineer

GLINTECO
QA Engineer
Business Systems & AI, with Product Support
Full-time | Hybrid, Hanoi | 3 to 5 years | Up to USD 1,000/month (gross)
Company Description
Glinteco is a Hanoi-based software company building custom technology for businesses in Australia, the US, and Vietnam. We design and deliver web and mobile applications, internal systems (ERP, CRM, HRM), and AI-enabled automation, alongside UI/UX, brand design, and QA. Every engagement is scoped and agreed before development starts, on either a fixed-price or time-and-materials basis.
Role Description
We are starting new CRM, HRM, ERP, and AI projects for our clients, and we need a QA engineer who protects quality from the first requirement to the last support ticket.
You will test business systems with complex workflows: approvals, permissions, payroll and attendance rules, sales pipelines, and reports. You will also test AI features, where the same input can give different outputs and "it works" is not a yes or no question. After go-live, you will be the first line of support for client users, so you will see how real people use what we build.
What you will do
Review requirements early with BAs and developers, and flag gaps before code is written
Write test plans, test cases, and test data for CRM, HRM, ERP, and AI modules
Run functional, regression, integration, and UAT testing on web and mobile
Test AI features: check output quality, edge cases, wrong or unsafe answers, and consistency
Build and maintain automated tests where it saves time
Handle L1/L2 product support for client users during business hours (around 20 to 30% of your time): triage tickets, reproduce issues, guide users, and escalate to developers with clear steps
Write and update user guides and release notes
