Manual QA Engineer

Dublemint is a growing IT company seeking an experienced Manual QA Engineer to join our team!

Our main project is an online casino platform with its web-based back office (gambling industry). We’re looking for someone who not only tests features, but also thinks critically about product quality, user experience, and long-term maintainability.

✅ You’re a perfect match if you have:
2+ years of manual QA experience

Strong critical thinking skills – you don’t just check if a feature “works”, you assess whether it makes sense for the product and the user. You notice when something looks or feels wrong, even if technically it’s “done”.

A sharp eye for detail and ability to evaluate user experience and visual quality (UI/UX) — even if you’re not a designer, you can spot misalignment, inconsistencies, or poor usability.

Experience with cross-browser and cross-platform testing

Familiarity with Dev Tools, error logs, and basic API testing

Ability to identify, document, and clearly communicate issues

English level: B1+ – you can clearly describe issues and write structured test cases

💡 It’s a plus if you also have:
Experience with slot platforms (apps, sites), slot games and gambling mechanics

Experience with version control systems (GIT or similar)

Knowledge of MySQL or other databases

Understanding of Agile/Scrum processes

Experience with automated testing tools

🎯 What you’ll do:
Perform comprehensive manual testing of web and mobile apps

Assess product quality beyond functionality – ask:Is it user-friendly?

Does it meet the modern product and UX standards?

Is it visually consistent and polished?

Would it make sense to a real user?

Collaborate with developers and managers to report not just bugs, but UX concerns, inconsistencies, and usability issues

Create and maintain structured test documentation

Test across devices and browsers

Ensure alignment with designs and business expectations

Raise questions and suggest improvements, even outside of strict specs

🎰 Gambling Platform Testing Scope
UI Testing – Validate the visual quality of the website, app, and back office: is everything clean, aligned, modern, and consistent with the overall design language?

UX Testing – Assess how intuitive and logical the user journey is — from registration and deposits to navigating the platform, managing settings, reports, and withdrawals.

Consistency & Integration Testing – Check how new features and changes fit into the existing product — visually, functionally, and contextually. Nothing should feel out of place.

Cross-Platform & Responsiveness Testing – Ensure smooth performance and proper display across different devices (desktop, mobile browsers, PWA) and screen sizes.

Bug Reporting & Critical Review – Identify and log bugs, but also go beyond that — spot UX flaws, inconsistencies, or confusing behavior. Be proactive in raising questions and suggesting improvements, even when the feature technically “works.”

📎 Conditions:
Remote work with flexible hours

Trial rate: $6/hour, rising to $7.5/hour after trial, paid monthly (option for more frequent payments if needed)

Minimum 6 productive hours per day, 5 days per week

Time tracking via Yaware is mandatory

If you’re not just a checker of tasks, but a guardian of product quality, we’d love to hear from you.
