Calibration and Maintenance Engineer

Permanent contract

C12 develops reliable & application-specific quantum computers, to solve highly complex computing tasks, currently out of reach of even most powerful supercomputers.

Building a quantum computer still needs innovators ready to tackle exciting challenges. C12 founders are convinced that only a new material for the qubit will bring a technological breakthrough.

C12 uniquely uses carbon nanotubes as the fundamental building blocks of its quantum processor. This high-purity material minimizes errors, radically improves performance and reduces hardware overhead for fault-tolerant computing. Combined with well-established semiconductor techniques, carbon nanotubes will help scale quantum computing, just as silicon revolutionized classical computing.

Founded in 2020, C12 is a fast-growing start-up, having raised a seed round of USD 10 million in June 2021 and building its own lab space in the center of Paris.

C12’s unique technology

At C12, a qubit, the fundamental functional unit of a quantum computer, is built from an ultra-pure carbon nanotube suspended above a silicon chip containing control electrodes and a quantum communication bus. Spin qubits coupled to a microwave cavity brings interesting perspectives for their individual control and manipulation as well as for the circuit architecture. A suspended isotopically pure 12C nanotube holds great promises in terms of stability, as it reduces all sources of decoherence (charge noise, nuclear spin noise, phonon relaxation).

C12 encourages all who feel qualified to apply. Recruitment decisions are based solely on qualifications, skills, knowledge and experience.

Your role at C12 Quantum

You’ll be responsible for calibrating our nanofabrication equipment on a regular basis. You will also be in charge of the maintenance of nanofabrication equipment hosted in our cleanroom. 

Your job will involve:

Calibration of tools (dry etch, e-beam, evaporator) and monitoring of this calibration by using metrology tools (AFM, SEM, EDX)

Regular maintenance of the cleanroom’s main equipment (e-beam, evaporator, SEM, ICP, etc.) with the assistance of our lab manager and the help of tool manufacturers

Creating, developing and maintaining the user manual, maintenance guideline and checklist, calibration log file and process data sheet

About you
  • Bachelor  or Master’s degree in Nanotechnology, Nanoscience, Quantum Physics, Experimental Physics, Vacuum Engineering, Electrical Engineering, Mechanical Engineering or a related field  
  • To be able to handle the maintenance : previous experience (> 12 months) of performing maintenance of cleanroom tools and other systems :

- Evaporator, dry etch, e-beam lithography, SEM (at least 1)

- Cryopumps, turbopumps, primary pumps, dry pumps 

- Chillers, filters, air compressors

  • To be able to work autonomously on calibration : previous experience (> 6 months) of performing nanofabrication autonomously in a cleanroom with the following processes or tools is desired:

- Dry etch

- Wet processes (cleaning, resist spinning and wet etch)

- Metrology tools (SEM, AFM)

- Metal evaporation

  • Meticulous attention to detail
  • Good English language and written skills

You should join us if
