Original job description

Summary We are searching for a talented engineer to join our cellular systems engineering team of innovators. In this role, you will be a key member of modem systems engineering team with a broad view of the end-to-end baseband modem.

Description Design and simulate state-of-the-art physical layer wireless communication algorithms, realizable with power and area efficient implementation. Implement system models and perform detailed performance investigations to allow performance sign-off and enable RTL development. Collaborate with hardware digital designers and firmware developers to bring-up and productize whole modem designs.

Responsibilities

Develop algorithms and implementable models for 5G/6G cellular system modem designs. Perform targeted and end-to-end characterization of the performance (Throughput, BLER, etc) of the modem and its components. Support modem specification definition documentation. Support algorithm integration and implementation up to testing on final silicon designs.

Minimum Qualifications Bachelors Degree in EE or equivalent. Knowledge of digital signal processing and design flow methodology. Experience in Matlab, C/C++ and/or Python for algorithm development, modeling (floating-point and fixed-point) and link-level simulation. Analytical skills (linear algebra, random processes, detection and estimation, etc.)

Preferred Qualifications Deep-knowledge of communication system theory (MIMO detection, estimation, mmWave, FEC), machine learning, signal processing and hardware design. Knowledge of 3GPP cellular standards (LTE and 5G) with a good visibility on the 6G activities. Experience with using AI/ML tools (e.g. Claude) for assisting in code design and algorithm development. Strong background in AI/ML and familiarity with tools such as PyTorch and TensorFlow.
