Job description

What Awaits You Every Day At Quobly

Based in the heart of the French Alps, Quobly is the result of more than 15 years of research into quantum computing. At Quobly we made the choice of practical and scalable quantum technology. Quobly offers you the opportunity to participate in the future of quantum computing; become a member of our science and innovation team as a Cryo-CMOS Design Research Engineer to turn scientific breakthroughs into products that matter.

Your main mission will be to generate new ideas, open up new avenues for the control, the addressing and the readout of large-scale quantum processors.

Technical Challenges

• Imagine and develop original concepts of circuit architectures fabricated with industrial CMOS technologies for the readout of large arrays of silicon spin QuBits at low temperature (figures of merit: speed, noise, overall consumption and local dissipation)
• Design these architectures with behavioral modeling first (Matlab, Python or Cadence), then with time, frequency and noise simulations with Cadence
• Implement the designs in mask layouts in an industrial framework (eg Calibre), running LVS, DRC and parasitics extraction analyses
• 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

Collaboration

• Collaborate with talented people, in a culture of transparency and autonomy.
• Work hand in hand with members of our technical teams.

You Are Special Because

• PhD in circuit design
• A minimum of 5 to 10 years’ experience in analog and mixed-signal IC design
• Knowledge of pixelized devices such as CMOS imaging sensors or RAM
• Ideally, knowledge of RF design

Nice to have:

• You have an industrial mind set
• Your curiosity and intellectual independence will make all the difference

Working at Quobly also means

• Working in Grenoble, home to some of the fastest-moving tech and industrial companies around, and a great base camp for a wide range of activities from outdoor and mountain sports to arts and culture.
• Grenoble offers an affordable lifestyle, ensuring you can plan for a comfortable future while advancing your career with us.
• The opportunity to develop in-demand skills alongside the best researchers in their fields.
• A collaborative work environment and a company culture where trust is paramount and where individual contributions are recognized.
• Presenting at international conferences to share our latest results.
• Work-life balance, with a standard package of 213 workdays per year.
• Work from home up to four days per week, depending on the position.
• Employer contribution to public transportation (75% covered) passes and human-powered mobility solutions.
