As part of your role, you will: 

• Lead the architecture and development of RF board designs. 
• Be able to design from schematic to layout RF boards.
• Collaborate effectively with cross-functional teams spanning multiple time zones, including mechanical, antenna, DSP and software engineers to define system requirements and architecture. 
• Drive architectural decisions and provide technical leadership to ensure the successful implementation of cutting-edge RF technologies. 
• Take responsibility in setting up a new RF lab, including the installation and configuration of advanced test equipment. 
• Conduct thorough analysis, simulation, and characterization of RF circuits to optimize performance metrics such as power consumption, noise figure, linearity, dynamic range and thermal management. 
• Hands-on experience for qualifying and testing boards in RF chambers. 
• Establish requirements and link budgets to establish best architecture and component selection. 
• Stay abreast of the latest advancements in RF technology and contribute innovative ideas to keep our solutions at the forefront of the industry. 

Qualifications / experience: 

• PhD or MS in Electrical Engineering or related field with a focus on RF is preferred. 
• Expertise in RF with specific experience in the following areas: 
  • RF blocks used in receivers: LNAs, filters & VGA. 
  • PCB Layout and board debugging and repair.
  • PLL & frequency synthesizers. 
  • Analog to digital converters. 
• Proven track record of successfully delivering complex RF designs from concept to production. 
• Experience in low power and ultra-low voltage designs. 
• AMS or other mixed-signal verification methodologies. 
• Expertise in RF simulation tools and familiar with standard RF measurement equipment. 
• Data-driven and evidence-based work methodology. 
• Experience in PCB design and Layout for RF frontends. 

Strong candidates will also possess skills in one or more of the following areas: 

• Strong understanding of RF system architectures and beamforming techniques.  
• Experience in direct sampling techniques with high-speed ADCs, and AMD/Xilinx RFSoC. 
• Experience with EMC measurements and standards.  
• Effective interfacing with digital signal processing engineers and FPGA developers. 
• Confident with scripting languages and track record of effective automation of repetitive tasks.

Access to US export-controlled software and/or technology may be required for this role. If needed, Spire will arrange the necessary licenses—this is not something candidates need to have before applying.#LI-DC1
