Cryo-CMOS Design Research Engineer for Quantum ICs

Quobly; Grenoble; Hybrid; EUR 90,000 - 130,000; Full time

Job summary

Quobly in Grenoble, France, is advancing quantum computing through practical cryo-CMOS technology. We seek a Cryo-CMOS Design Research Engineer to translate scientific breakthroughs into products that matter, generating new ideas for control, addressing, and readout of large-scale quantum processors.

The role centers on designing CMOS readout architectures, simulating with Matlab/Python/Cadence, and integrating layouts in an industrial flow.

Qualifications

• PhD in circuit design.
• 5–10 years of analog and mixed-signal IC design experience.
• Knowledge of CMOS imaging sensors or RAM.
• RF design knowledge is a plus.

Responsibilities

• Generate new ideas for control, addressing and readout of large-scale quantum processors.
• Design architectures with behavioral modeling first (Matlab, Python or Cadence), then with time, frequency and noise simulations.
• Implement designs in mask layouts in an industrial framework (e.g., Calibre), running LVS, DRC and parasitics extraction.
• Interact with physicists of the quantum team, process integration engineers and the circuit design team.
• Actively contribute to the testing of fabricated circuits at low temperatures by interacting with the testing team.
• Actively participate in internal scientific discussions by contributing ideas to the scientific and innovation roadmap.
