RF Systems Architect (Control Algorithms)

Quick Facts

• Role: RF Systems Architect (Control Algorithms)

• Focus: Intelligent control algorithms for cellular RF Front-End hardware

Description

Design and specify control algorithms that coordinate RF transceivers with RF Front-End modules for next-generation cellular products. Translate cellular capabilities such as SRS antenna switching, MIMO, and Multi-SIM into system requirements and concrete control flows, balancing RF performance, power consumption, and thermal limits. Work closely with teams across the cellular stack to bring architectures from concept through validation.

Responsibilities

• Analyze cellular radio access use cases and specify required RF hardware control algorithms.

• Develop optimization strategies to maximize RF performance and hardware utilization, including multi-SIM scenarios.

• Author comprehensive system architecture specifications to guide design, implementation, and validation.

• Drive end-to-end system performance with baseband, SoC, RF firmware, and RF hardware teams.

• Validate system architectures and algorithms via simulation and automated requirements analysis.

Requirements

• BSEE required.

• Deep understanding of 5G NR and LTE-Advanced physical layer procedures, especially MIMO, SRS, and carrier aggregation.

• Strong working knowledge of RF Front-End architectures and component-level system impact (PAs, LNAs, filters, switches).

• Proven track record developing control algorithms, state machines, or system-level models for complex hardware.

• Proficiency in Python, MATLAB, or C/C++ for data analysis, system modeling, and algorithm development.

• Ability to analyze complex trade-offs such as routing flexibility vs insertion loss, or throughput vs battery life.

• Strong communication skills and ability to work across cross-functional teams.

Benefits

• Opportunity to directly balance RF performance, power consumption, and thermal limits while contributing to cutting-edge 5G/6G wireless experiences.
