Description

In this role, you will be part of an industry-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.

Responsibilities

• Your daily work includes the following tasks:
• Translate system-level and performance requirements into requirements for the TX line-up and TX features, including RF algorithm specifications for RFICs and system firmware.
• Understand and specify RF algorithms (e.g. power control, calibration) and define the RF control infrastructure, including compute resources, interfaces, memory and timing constraints.
• Research, design, and prototype machine learning models—including neural networks and reinforcement learning for RF transmitter applications such as power control, calibration, and digital pre-distortion.
• Develop and maintain simulation environments in Python or MATLAB to model RF systems and test AI algorithms.
• Analyze simulation data to evaluate model performance, identify trade‑offs, and propose improvements.

Minimum Qualifications

• Proven years of relevant experience in RF, including cellular transmit architectures, or PhD degree with previous work on cellular topics.
• 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.
• Familiarity with RF systems and transceiver architecture, including lineup design and component‑level trade‑offs (e.g. gain, linearity, noise, power, thermal).
• Solid theoretical grounding and hands‑on experience with classical machine learning techniques (e.g., clustering, dimensionality reduction) applied to regression and classification problems.
• Solid theoretical understanding and hands‑on experience with neural networks for regression and classification problems.
• Practical experience across supervised, unsupervised, and reinforcement learning.
• Strong analytical skills and the ability to collaborate and communicate across multicultural, global teams.
• BSEE or MSEE
• Proficiency in English.

Preferred Qualifications

• Initial expertise in transmitter system‑level concepts and control procedures like power control, digital predistortion, envelope tracking.
• Background in digital signal processing.
• Understanding of SoC integration constraints and multi‑chip RF architectures.
• Ph.D. in Electrical Engineering or equivalent.
• The minimum salary pursuant to the applicable collective bargaining agreement amounts to €62,610 gross per year for full‑time employment. Actual salaries are oriented at current market salaries and take your qualifications and experience into account.
