About the role

Engineer needed to design intelligent control algorithms for RF Front-End hardware, translating 5G/6G use cases into optimized control flows to balance RF performance, power, and thermal limits across RF transceivers and Front-End modules. Collaborative role interfacing with baseband, SoC, RF firmware, and hardware teams to drive end-to-end system performance.

Responsibilities

  • Analyze complex cellular radio access use cases and specify the required RF hardware control algorithms.
  • Develop optimization strategies that maximize RF performance and hardware utilization for demanding scenarios like multi-SIM.
  • Author comprehensive system architecture specifications to guide design, implementation, and validation teams.
  • Drive end-to-end system performance by collaborating tightly with baseband, SoC, RF firmware, and RF hardware teams.
  • Validate system architectures and algorithms through rigorous simulation and automated requirements analysis.

Qualifications

  • BS and 10+ years of relevant industry experience required.
  • Deep understanding of 5G NR and LTE-Advanced physical layer procedures, particularly involving MIMO, SRS, and carrier aggregation.
  • Strong working knowledge of RF Front-End architectures and the system-level impact of components like PAs, LNAs, filters, and switches.
  • Proven track record of 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 critically analyze complex trade-offs, such as routing flexibility versus insertion loss, or throughput versus battery life.
  • Strong communication skills with a proven ability to work across diverse, cross-functional teams to solve highly complex, multi-disciplinary problems.
  • MS or PhD in Electrical Engineering, Physics, or a related field.
  • 3+ years of industry experience in RF systems or transceiver architectures with a focus on advanced cellular topics.
  • 5+ years of experience in RF systems engineering or 10+ years in communications circuit design.
  • Hands-on experience with RF filter technologies, power amplifier characterization, and Front-End module integration.
  • Expertise in designing and simulating analog and digital signal processing paths.
  • Experience applying Machine Learning or AI techniques to solve system-level optimization problems.
  • History of balancing cutting-edge hardware innovation with practical high-volume manufacturing constraints.
