As a leading technology innovator, Qualcomm pushes the boundaries of what's possible to drive the evolution of wireless connectivity, delivering industry-leading modem innovations across 5G and next-generation cellular technologies. Its modem innovation has enabled breakthrough advances in performance, power efficiency, global interoperability, and commercialization at scale.
We are seeking a motivated engineer to join the Modem System Test (MST) team in Sulzbach am Taunus, Germany (Frankfurt area). In this role, you will contribute to building next-generation wireless technologies including 5G NR and emerging 6G systems, with opportunities to apply AI/ML techniques to end products and engineering workflows. You will work closely with cross-functional teams, including software development, system design, hardware design, and RF design, to integrate, test, characterize, certify, and commercialize 6G/5G modem products for global markets.
You will directly impact the quality, performance, and commercialization of global modem products, enabling cutting-edge wireless experiences across mobile devices and networks.
Key Responsibilities:
You will support verification and performance evaluation for complex digital modem products across 6G and 5G cellular technologies. Core responsibilities include:
Validate end-to-end system functionality and performance across the cellular protocol stack (PHY, MAC/RLC/PDCP, RRC, NAS, TCP/IP).
Define modem key performance indicators and evaluate system performance, optimizing based on data from conducted, radiated, and live 6G/5G network testing.
Develop and execute system-level test strategies, methodologies, and test plans for modem features and use cases.
Analyze 3GPP specifications and carrier requirements, translating them into robust validation scenarios and test coverage.
Perform log analysis, debugging, and root cause investigation of modem issues across lab and field environments.
Support feature integration, certification, and commercialization of global wireless products.
