In short

Qualcomm is seeking a Systems Engineer to design and validate RF and channel emulation architectures for 5G NR and LTE. This role involves analyzing specifications, translating requirements, theoretical analysis, lab integration, and supporting commercialization. The position requires a Bachelor's degree with relevant experience or a Master's/PhD and strong programming skills in C/C++, Matlab, and Python.

Responsibilities

Analyze latest 3GPP and other specifications to derive requirements.
Translate requirements into analog/RF architecture, calibration, and analog/digital compensation.
Perform theoretical analysis and simulation of features, algorithms, and implementation choices.
Conduct lab integration and subsequent analysis of RF and channel emulation features.
Present and document specifications, designs, and results to cross-disciplinary and diverse teams.
Support the implementation and commercialization of features by providing test vectors, logs, and analysis.

Requirements

Bachelor's degree in Computer Science, Engineering, Information Systems, or related field and 2+ years of Electrical Engineering, Hardware Engineering, Systems Engineering, or related work experience.
OR Master's degree in Computer Science, Engineering, Information Systems, or related field and 1+ year of Electrical Engineering, Hardware Engineering, Systems Engineering, or related work experience.
OR PhD in Computer Science, Engineering, Information Systems, or related field.
Graduate level classes, equivalent training or experience in: Probability and Random Processes, Digital Signal Processing, Wireless Channel Models and their Emulation, Statistical Signal Analysis or Signal Detection and Estimation, Digital Communications, RF systems design, Programming in C/C++, Matlab and Python.
Ability to work on a diverse team and interact in a diverse and inter-disciplinary engineering organization.
Strong communication skills, including both written and oral skills.
Knowledge of 5G NR and LTE physical layer specifications.
Knowledge of mixed-signal RF systems components such as ADC, DAC, digital and analog filters, mixed signal, PA, LNA, RF calibration, digital and analog compensation methods.
Knowledge of analog/RF impairments such as IQ mismatch, intermodulation, unwanted spurious sources, signal compression, noise figure, phase noise, and characterization.
Knowledge of fading channel models (Jakes and cluster-based) and deterministic models for high-speed train scenarios.
Knowledge of OFDMA and SC-FDMA
Experience with RF interfaces and digital mitigation of RF distortion.
Masters or Doctorate in Electrical Engineering.
