QA Intern, Manual & API Testing

About TOCH

TOCH is a cross-platform encrypted chat application built with Kotlin Multiplatform (KMP), targeting Android, iOS, and Desktop. It utilizes the Signal Protocol for end-to-end encryption, WebSocket-based real-time messaging, WebRTC calls, and a Go microservices backend.

Role Overview

This is a hands-on role for a motivated QA Intern eager to learn manual and API testing in a fast-paced, real-world product environment. You will work alongside experienced engineers to test a multi-platform chat app, covering messaging, calls, encryption, and media.

Key Responsibilities

• Execute manual test cases for chat, calling, media sharing, and notification features on Android and iOS devices.
• Learn and perform API testing using Postman or similar tools: send requests, validate responses, and check error handling.
• Test WebSocket-based real-time events (message delivery, typing indicators, online status).
• Verify app behavior across different network conditions (offline, slow network, reconnection).
• Log detailed bug reports with clear reproduction steps, screenshots, and device/OS details.
• Help maintain and update the regression test suite.
• Participate in daily standups and sprint ceremonies.
• Assist in exploratory testing before releases.

Requirements & Tech Stack

• Pursuing or recently completed a degree in Computer Science, IT, or a related field.
• Basic understanding of software testing concepts (test cases, bug lifecycle, regression testing).
• Familiarity with REST APIs (HTTP methods, status codes, JSON payloads).
• Exposure to API testing tools like Postman.
• Ability to use Android and iOS devices for testing (installing builds, capturing logs).
• Eagerness to learn, ask questions, and take ownership of assigned tasks.
• Good written communication skills.

Bonus Points

• Personal projects or coursework involving mobile app testing.
• Basic knowledge of databases (SQL queries).
• Awareness of messaging app features.
• Familiarity with version control (Git basics).
• Any exposure to WebSocket or real-time application concepts.
• ISTQB Foundation Level certification or equivalent coursework.

Tech Stack You'll Be Exposed To

• Platforms: Android (Jetpack Compose), iOS (SwiftUI), Desktop (Compose Multiplatform)
• Backend: Go microservices, REST APIs, WebSocket
• Database: SQLDelight
• Encryption: Signal Protocol (X3DH, Double Ratchet, Sender Key)
• Tools: Postman, Git, Jira/Linear, Android Studio, Xcode
