We are looking for a Staff RF Engineer. As an RF Engineer, you’ll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world’s best quantum computers to solve the world’s most complex problems. 

You will design and validate high performance Integrated Microwave Assemblies (IMAs) for laser control, including low phase noise RF synthesizers (0.1-15 GHz), phase-lock loops, AGC loops,  power amplifiers (1- 5 W), Mixers, Switches and laser amplitude/frequency stabilization systems.

Responsibilities: 

• Expert in RF / Analog circuit design, test and optimization up to 15 GHz
• Detailed knowledge of RF/Analog and mixed-signal design techniques including synthesizer design, mixers, amplifiers, PLLs, low phase noise VCOs, filters, etc.
• Perform RF engineering design tasks, including requirements analysis, specification generation, component selection, simulation, schematic capture, and board layout
• Design, simulate, and test analog and digital phase lock loops for RF synthesizers and laser frequency/phase locks
• Direct workflow of PCB designers to assure superior RF performance of layouts

You’d be a good fit with: 

• At least five years of technical experience in RF/Microwave engineering and circuit design of synthesizers and phase locked loops
• Bachelor’s degree in electrical engineering or other relevant technical degree from an accredited university
• Experience using AWR Microwave Office simulation software or similar
• Experience in creating complete schematics for controlled RF modules using a schematic capture tool like Altium Designer (preferred), OrCAD or PADS
  
  

You’d be a great fit with: 

• Master’s degree or PhD in electrical engineering, physics, mathematics or other relevant technical field
• At least ten years of technical experience in RF/Microwave engineering and circuit design
• Experience in designing plugin modular RF cards for PXI, VMA or VPX standards
• Understanding of EMI, EMC, ESD standards and implementation
• Familiarity with Electro Optical Modulators and Acousto Optical Modulators
• Knowledge of I2C, Verilog, microcontroller, FPGA is a plus
