About The Position

As a Cellular System Engineer, you will be responsible for the pre- and post-silicon bring up, and validation of end-to-end cellular systems. You will understand and map systems algorithms and requirements to HW/FW architecture, simulation and emulation-based validation of the control flows and PHY/L1 algorithms.

Requirements

• BS and 10+ years of relevant experience is required
• Knowledge of cellular communication standards: 6G, 5G NR, 4G LTE, PHY Uplink channels and signals
• Deep-knowledge of communication system theory and signal processing will be important for this role to design algorithms such as LDPC, Polar, Turbo encoder design, signal estimation and detection, automatic gain control, RF impairments estimation and correction, channel estimation, OFDM, MIMO detection, signal waveform generation and upsampling, etc.
• Experience with Matlab, C/C++ and/or Python for algorithm development, modeling (floating-point and fixed-point) and link-level simulation.

Nice To Haves

• Experience in low power algorithm design for power critical applications is helpful.
• Experience in E2E timeline analysis for time-critical algorithms is helpful.
• Experience in chip bring-up including the use of lab equipment such as protocol test equipment, spectrum analyzers, signal generators, power meters, etc..
• In-depth knowledge of wireless communication systems with hands-on experience in lab testing & characterization.
• Strong analytical skills (linear algebra, random processes, detection and estimation, etc.)
