Résumé du poste

C12 Quantum Electronics in Paris seeks a Senior Quantum RF Engineer to lead RF/microwave system design for quantum hardware, spanning room-temperature electronics to cryogenic interconnects and device packaging.

You will craft low-noise signal chains, optimize phase noise and loss, and collaborate with scientists, engineers, and suppliers to push scalable quantum technology forward. A PhD or Master’s with deep RF experience is required.

Qualifications

• Master’s degree or PhD in electrical engineering, applied physics, quantum engineering, or a related field.
• Substantial experience designing and testing RF or microwave systems.
• Strong knowledge of S-parameters, impedance matching, transmission lines, resonators, noise, nonlinearities, and signal integrity.
• Experience with electromagnetic and circuit-simulation tools such as Ansys HFSS, CST Studio Suite, Keysight ADS, or equivalent.
• Hands-on experience with RF laboratory instrumentation and measurement techniques.
• Experience designing RF PCBs, microwave assemblies, or integrated interconnects.
• Proficiency with Python, MATLAB, or similar tools for automation and data analysis.
• Demonstrated ability to lead complex technical projects and resolve multidisciplinary engineering problems.

Responsabilités

• Design RF and microwave architectures for quantum control, readout, amplification, and signal routing.
• Develop components and subsystems including filters, amplifiers, mixers, couplers, resonators, attenuators, bias networks, and impedance-matching structures.
• Design and validate room-temperature and cryogenic RF signal chains.
• Perform electromagnetic simulation, link-budget analysis, noise analysis, and signal-integrity optimization.
• Characterize components and systems using vector network analyzers, spectrum analyzers, signal generators, oscilloscopes, and noise-measurement equipment.
• Optimize phase noise, noise figure, gain, linearity, isolation, bandwidth, cross-talk, and thermal loading.
• Develop calibration, de-embedding, and automated test procedures.
• Support integration of RF electronics with quantum processors, cryostats, interposers, PCBs, cables, connectors, and advanced packaging.
• Diagnose performance limitations involving reflections, interference, grounding, shielding, drift, and thermal effects.
• Define requirements, interfaces, test plans, and acceptance criteria for RF subsystems.
• Lead technical reviews and collaborate with quantum scientists, electronics engineers, packaging teams, firmware developers, and external suppliers.
• Mentor junior engineers and contribute to RF design standards, technology roadmaps, and laboratory best practices.
