About The Position

We are looking for a Senior Microwave Characterization Engineer to join our Quantum Interconnect Division. As a Senior Microwave Characterization 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. In this role, you will be responsible for developing and executing rigorous microwave characterization of our quantum interconnects, as well as leveraging data to improve the performance of our devices. The ideal candidate is someone who is a collaborative and innovative problem-solver.

Requirements

5+ years of professional experience in RF/Microwave characterization, testing, and metrology within the quantum, semiconductor, or advanced technology sectors, or an equivalent combination of education and experience.
Master's Degree in Electrical Engineering, Physics, or a related field, or equivalent practical experience.
Proven technical expertise in operating Vector Network Analyzers (VNA), spectrum analyzers, and arbitrary waveform generators.
Demonstrated proficiency in programming languages (e.g., Python, MATLAB) for instrument control and data processing.
Experience with simulation software (COMSOL, HFSS…)
Strong collaborative and communication skills essential for working within a multi-disciplinary engineering and scientific environment.

Nice To Haves

Ph.D. in Electrical Engineering or Physics.
Direct experience with cryogenic RF/Microwave measurement techniques and system integration.
Familiarity with quantum computing principles or trapped-ion systems.
Experience in designing, simulating, and characterizing microwave components and transmission lines (e.g., coplanar waveguides, microstrip).
Prior experience in a fast-paced, high-tech R&D or startup environment.

Responsibilities

Design and execute comprehensive microwave characterization experiments for next-generation quantum interconnects - at room- and cryogenic temperatures.
Develop and implement automated testing procedures using software tools to accelerate characterization cycles.
Validate measurement data by performing correlating electromagnetic simulations
Analyze complex RF/microwave data to identify critical performance metrics and troubleshoot system deficiencies in close collaboration with hardware and design teams.
Maintain, calibrate, and upgrade advanced microwave test equipment (e.g., VNAs, spectrum analyzers, power meters) in a laboratory setting.
Document all characterization findings, procedures, and reports with precision for internal knowledge transfer and system optimization.
