IonQ is seeking a Senior Electronics Engineer to join the R&D department in Geneva. This is a hands-on technical role focused on designing and owning high-performance electronic subsystems that drive and read out ultra-sensitive, fast opto-electronic modules such as lasers, SPADs, and interferometers. The role spans architecture, schematic and PCB design, lab bring-up, and verification, with emphasis on analog, RF/high-speed, and mixed-signal design to enable robust, industrial-grade quantum computing products.
Key responsibilities include developing complex electronic hardware from early prototypes through industrialized modules, including low-noise amplification, high-speed/RF signal conditioning, drivers for opto-electronic components, A/D conversion, and optimized power-supply blocks. You will design high-performance, low-noise mixed-signal PCBs applying robust partitioning, grounding, shielding, and layout techniques to preserve signal integrity and minimize coupling. You will define and review block specifications with system, optical, and firmware engineers, and lead technical trade-offs around noise, bandwidth, timing, and electromagnetic compatibility.
The role includes planning and executing bring-up and verification in the lab using structured test methods and data-driven analysis to ensure compliance with requirements and reliability targets. You will coordinate and technically guide subcontractors and suppliers, and help evolve the team's design process, documentation, and review practices. You will act as the analog/RF reference in R&D, driving cross-team specifications, design reviews, and supplier execution to deliver production-ready hardware.
Required qualifications include a Bachelor's or Master's degree in Electronic or Opto-electronic Engineering (or equivalent) and at least seven years of relevant experience designing complex, high-performance hardware modules. Strong expertise in analog and mixed-signal design (low-noise, precision, and high-speed) and RF fundamentals (impedance matching, transmission lines, filtering) is essential, along with applied signal-integrity knowledge.
