Responsibilities include: - Develop automated test scripts to characterize and optimize parametric performance on RF sub-system level, or block level, at a laboratory test bench or at remote test stations - Assess key performance parameters according to design specifications or 3GPP specifications, debug and optimize RF parameters on system level to meet 3GPP compliance in mass production (2G/3G/4G/5G) in SC / CA for FDD / TDD mode - Collaborate closely with tooling experts to program routines in a framework for HW regression tests - You will develop your verification plans in a cross functional team together with design and system leads - You operate with RF measurement equipment and communication tester for cellular standards in non-signaling and signaling mode on modem level - Analyze issues & root cause identification encountered during investigating the DUT, with the ability to identify and solve problems as well providing ideas for workarounds, either alone or in collaboration with other teams - Support RF feature definition with responsibility for implementation and validation (digital predistortion) - Ownership varies from component level / SoC bring up to fully featured operation on modem level - Connect the work carried out between existing pre-silicon investigations and implementation in post silicon environment and product design - Prepare and present status & progress tracking
