About the Role

We are looking for a Senior QA Engineer to work on an interactive in-flight map app providing real-time flight info and content on Android, iOS, and Linux devices. The product integrates with a Docker-based server infrastructure.

The codebase is in C++ and QML, with the main repository in Git and airline-specific configurations in Perforce. Testing is done across multiple virtual environments, requiring flexibility and strong technical understanding.

Test cases are managed in Qase, and issues are tracked in Jira. You will ensure product quality, perform thorough testing, analyze complex issues, and collaborate with developers and product managers to define testing strategies and reproduce defects.

Key Responsibilities

- Test native client applications on Android, iOS, and Linux platforms.
- Test server-side components, including those running in Docker containers.
- Work across different vendor environments using virtual machines (e.G., in VirtualBox or VMware).
- Develop comprehensive test strategies and write detailed test plans for new features and releases.
- Execute functional, regression, and integration testing across multiple configurations.
- Perform API testing using Postman and similar tools.
- Validate communication protocols such as HTTP requests, multicast messages, and MQTT messaging.
- Analyze network traffic using Wireshark or similar tools.
- Use MQTT Explorer to inspect, monitor, and verify MQTT communication.
- Conduct performance, memory, and resource usage testing, including monitoring and reporting on resource consumption using profilers.
- Investigate issues using Linux command-line tools and system logs.
- Use PuTTY, WinSCP, or similar tools to connect to remote devices and servers.
- Work with content stored in databases, using SQL queries and tools like DB Browser to verify data structure and integrity.
- Collaborate with the development team to define testing approaches and ensure full coverage.
- Maintain and execute test cases in Qase, and manage defects and progress in Jira.
- Document test results, issues, and testing procedures clearly and consistently.

- Familiarity with Docker and understanding of server-side systems.
- Knowledge of XML and JSON structures.
- Proficiency with remote access tools such as PuTTY, WinSCP, or equivalents.
- Proven ability to develop test strategies and write test plans.
- Knowledge of version control systems (Git for source code and Perforce for configuration management).
- Experience testing native or cross-platform applications.
- Solid understanding of client-server architecture.
- Experience with Qase (test case management) and Jira (bug tracking).
