System Test Engineer
Description:
Overview:
Candidate will be responsible for verifying software's protocols/features and characterizing system performance in one or more of the following technology areas: CDMA2000, 1xEV-DO, WCDMAGSM/GPRS, LTE, TD-SCDMA, 5G. Candidates can expect to be responsible for testing and verifying physical layer and/or network protocol requirements for complex digital modem ASIC products supporting LTE, UMTS (HSPA+) and IS-2000 technologies. Will conduct engineering tests and detailed experimental testing to collect design data or assist in research toward improving the quality of ASIC products. Candidate will be working with a multi-discipline team (Software Development, System Design, Customer Support, ASIC Design, RF Circuits and Hardware Design, etc.) to integrate, test and commercialize QCT products. Successful candidate must have strong communication skills, must be an effective team player, and be able to work independently. Responsibilities include system level feature integration and test, developing/executing test strategies and test plans, troubleshooting/analyzing problems, optimizing system performance, executing inter-operability tests, post processing Logs collected and supporting customers with product commercialization.
