Overview:
IT Network team is looking for a motivated Quality Assurance (QA) Engineer to help validate the quality, performance, and reliability of our mobility network infrastructure, device portfolio, and customer-facing applications (mobile and web). You ll design and execute tests, document results, collaborate closely with engineers and product partners, contribute to automation, and help ensure a smooth customer experience across carrier-grade services.

Key Responsibilities:
Test planning & execution: Create, maintain, and execute manual and automated test cases for devices, APIs, and web/mobile apps (functional, integration, regression, and exploratory).
Defect management: Log, triage, track, and verify fixes using a work tracking system (e.g., Jira) with clear, reproducible defect documentation.
Requirements testability: Review user stories/requirements for clarity and testability; contribute test conditions and acceptance criteria early in the lifecycle.
Performance & reliability support: Assist with performance, load, and stress testing to baseline and monitor system behavior and customer experience.
Security & compliance support: Execute security test checks and follow secure test data handling; escalate issues that implicate security or compliance.
Environment & data setup: Configure lab devices, emulators/simulators, and test environments; manage test data and resets to ensure repeatability.
CI/CD awareness: Run/monitor tests in pipelines (e.g., Azure DevOps/Jenkins/GitHub Actions); interpret results and file issues with high-quality evidence (logs, screenshots, traces).
System & network validation: Capture and analyze mobility network traces/logs using pcap, logcat, syslog, and tools like Wireshark. Familiarity with Ericsson RADCOM suite for network-level tracing in support of device, RAN/core, and application troubleshooting.
Cross-functional collaboration: Partner with developers, product managers, UX, and vendors to reproduce issues, validate fixes, and align on acceptance.
