Description
Description:
WiFi test engineer will provide troubleshooting support and optimization analysis. The individual will be part of a cross-functional team developing automation and testing of technologies and applications using Cable Modems/Multimedia Terminal Adapters. The primary responsibility is the in-lab integration, and test of Multimedia Terminal Adapters; determine root cause of problems and escalate issue with the appropriate code fix for resolution. Understanding WIFI is a MUST.
Job responsibilities on a day-to-day basis. (key challenges)
Development of test use cases, execution of the test cases, identify any problems in vendor software & hardware, isolate the issues, communicate them clearly to higher levels of engineering and management to drive fixes, and then verify the fix condition.
Core Responsibilities:
Execute scripted test cases on WiFi CPE equipment using pre-defined test plans and technical requirements as input. Design and Ad-Hoc test scripts and test cases.
Analyze test execution results and record test data in ALM systems.
Report and track defects and provide regular updates on test status; understand why the defect occurred
Technical interface with Engineering teams to reproduce, isolate, and troubleshoot issues found in testing, and/or reported by the customer.
Participate in daily scrum meetings to provide status, owning next actions for testing.
Prepare Test Strategy and Test Schedule, take an active role in Test Project Planning meetings.
Active participation in test design, test execution, and test reporting activities.
