You will validate and characterize wireless system performance across wireless technologies towards industry conformance, regulatory compliance, carrier and use case requirements. You will perform failure analysis of issues with cross-functional engineering teams and drive issues to closure. You will be responsible to complete certification testing. Examples of activities you may be involved in are:- Executing validation and characterization test plans to meet industry, emissions and performance requirements. - Bringing-up device-under-test, help define test requirements and implement test systems setups for validation preparedness.- Tracking validation status, analyze results, communicate issues and insights from data.- Performing failure analysis to understand low margin or failing behaviors making use of experimental SW/FW and modified development hardware. - Collaborating with vendors, technology suppliers and cross-functional staff to optimize RF parametric performance.- Supporting manufacturing test and Certification of Apple products.
