Alice & Bob is developing the first universal, fault-tolerant quantum computer to solve the world’s hardest problems.
The quantum computer we envision building is based on a new kind of superconducting qubit: the Schrödinger cat qubit 🐈‍⬛. In comparison to other superconducting platforms, cat qubits have the astonishing ability to implement quantum error correction autonomously!
We're a diverse team of 180+ brilliant minds from over 30 countries united by a single goal: to revolutionise computing with a practical fault-tolerant quantum machine. Are you ready to take on unprecedented challenges and contribute to revolutionising technology? Join us, and let's shape the future of quantum computing together!

About the role :

As nanofabrication backend technician, you will play a key role in bringing into reality the QPU designs imagined by the company. Your technicity and attention to the details will directly contribute to our technical excellence and speed of execution, shaping the future of quantum computing. For this position, we are seeking a technician with a background in backend / electrical tests in semiconductor/superconductor processes to join our talented team.

As part of the Quantum Hardware department, the “nanofabrication backend” team plays a pivotal role in operating and developing the “backend of line” used for manufacturing Alice&Bob Quantum Processor.

The team is in charge of:

  • operating the tools for the regular delivery of test chips
  • developing/improving new processes (for better quality/leadtime/chip selection…)
  • overseeing its own tools (daily check of the tools, ensuring maintenance schedules are followed, 1st level of troubleshooting)
  • selection, installation and qualification of new tools

Key Responsibilities:

    • Execute the day-to-day operations, which include :
      • Room temperature electrical testing of wafers and chips
      • Dicing
      • Cleaning of the chips
      • Optical inspection
      • Wirebonding of chips inside sample holders
      • Assembly of sample holders
      • Failure analysis
  • Execute the day-to-day operations, which include :
  • Process development: Contribute to the R&D tests for improving the process/recipes, keeping up with the latest technological progress.
  • Tools responsibility: Be responsible for one or several tools of the team (following preventive maintenance plan and managing corrective/troubleshooting when necessary). This includes the responsibility of training new users on the tool if necessary.
  • Continuous Improvement: Contribute to continuous improvement projects in the team (troubleshooting, A3, failure analysis…)
  • Documentation & Reporting: Ensure standard operation procedures stay up-to-date, and document the operations and results obtained.

Requirements:

    Educational Background: BSc in a related field (DUT « Electronique », « Mesures physiques », « Microélectronique » or equivalent)

    Experience: Mini 5 years of experience as laboratory or operation technician in an industrial or R&D environment. Experience in a semiconductor or electronic environment is considered as a plus.

    Experience in one part of our backend process (wirebonding, dicing, electrical testing) is considered as a plus.

    Skills

  • Rigorous, strong adherence to processes
  • Autonomous
  • Prone to continuous improvement
  • Ability to work as part of a multi-disciplinary team without friction
  • Ability to troubleshoot and solve hardware issues
  • English = intermediate (required to communicate with Alice&Bob team, and suppliers)
Benefits:
- Our success is your success : own it with our BSPCE plan
- Direct IP Compensation: Earn substantial bonuses for driving the core patents that define our quantum architecture.
- A Parental plan including additional benefits such as crèche support or additional days-off to take care of under 12 years old children
- Subsidized membership with Urban Sports Club
- Mental health support with moka.care
- 25-day vacation policy (as per French law) + RTT
- Half of transportation cost coverage (as per French law), or yearly allowance for the die-hard bicycle users
- Competitive health coverage, with Alan.
- Meal vouchers with Swile, as well as access to a fully equipped and regularly stocked kitchen
- French language courses covered by the company for those interested
