Full Description

QA Engineer (Manual) + React Native Developer

💰 Salary: $2,000 / month 🌍 Remote

AlemX is looking for a hybrid specialist — someone who doesn’t just find bugs, but can fix them directly in React Native code.

This role is for a QA engineer with a developer mindset: you test manually, reproduce issues precisely, understand the root cause, and deliver clean, safe fixes ready for release.

🧪 What you will do — Manual QA

Perform manual testing of a mobile app (iOS & Android): functional, regression, smoke, exploratory

Create and maintain test cases and checklists

Write clear, structured bug reports (steps to reproduce, expected vs actual results, environment details, screenshots/videos/logs)

Validate critical flows: onboarding & authentication, profile, wallet and balance updates, transactions, API-driven screens, advertiser and billing logic

Re-test fixes and ensure no regressions before release

💻 What you will do — React Native Development

Fix bugs you discover yourself in React Native (TypeScript / JavaScript)

Debug UI issues, navigation, state management, error handling, and edge cases

Identify whether issues originate from frontend logic, API responses, or integrations

Make quality improvements: refactoring where needed, improving stability, preventing crashes, polishing UX

Participate in code reviews and help stabilize builds before releases

✅ Must-have requirements

Proven experience in manual QA for mobile applications

Hands-on experience with React Native (real production bug fixing, not only demo projects)

Understanding of client-server interaction: REST APIs, JSON, authentication flows, status codes

Strong debugging mindset: reproduce → isolate → explain → fix → verify

High attention to detail and product quality

⭐ Nice-to-have

Automation experience or willingness to introduce it (Jest, React Native Testing Library, Detox)

Experience with Sentry, Firebase Crashlytics, or similar tools

Background in fintech, payments, billing, or transactional products

Experience with advertiser dashboards or complex business logic

🧩 Work format & conditions

Remote

Fast feedback loops and product-focused team

Monthly compensation: $2,000

Long-term collaboration opportunity
