Full Job Description
In this role, you will be part of an industrial-leading RF Transmitter Systems Engineering team. You will work closely with other architecture- and systems engineering teams, RF design teams and SW teams to assess, specify and drive transmitter concepts with focus on leading-edge performance and uncompromised quality as baseline for differentiating products. Your daily work includes the following tasks. BS and 10+ years of relevant industry experience required. Knowledge of cellular radio/3GPP standards (GSM, UMTS, LTE, LTE-A, 5G NR), including RF aspects as well as system use cases and TX waveforms. Familiar with PHY to transceiver interfaces and RF systems and transceiver architecture, including lineup design and component-level trade-offs (e.g. gain, linearity, noise, power, thermal). Understand how to translate top-level PHY and RF requirements into specifications for transceiver architecture and building blocks, including dimensioning digital control systems for RF applications (CPU, memory, buses, real-time constraints). Experience with HW and SW co-design and clear understanding of trade-offs between digital HW and firmware implementations. Strong analytical skills, proactive user of AI tools, and ability to collaborate and communicate across multicultural, global teams. 5+ years of relevant experience in RF, including cellular transmit architectures, or PhD degree with previous work on cellular topics. Initial expertise in PHY and RF transmitter system-level concepts, PHY control and data translation into modulations, and control procedures like power control, digital predistortion, envelope tracking. Software programming experience in PHY and RF modeling and simulation. Familiar with mmWave architectures, phased arrays and control concepts. Background in digital signal processing and mixed-signal circuit design. Understanding of SoC integration constraints and multi-chip RF architectures.
