Superconducting Qubit Design
il y a 2 jours
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 are at the forefront of the quantum race, competing with tech giants such as Google or IBM, and we are growing fast after securing €100 million of funding in 2025 to develop our unique technology.
Currently 100+ and counting, between physicists, PhD students, engineers and experienced business professionals, we are united to reach our ambitious goal. Are you a quantum pioneer? Join us on a mission to reshape the future
**About the role**
As a Superconducting Qubit Design Engineer, you will be part of the development of our new, cutting-edge **microwave architecture** embedding the **superconducting resonators**, and specifically designed to preserve and control their quantum states.
**Your mission will be to develop, simulate and troubleshoot microwave circuits and their controls.** You will work hand in hand with the experimental physicists building the quantum processor and develop state-of-the-art hardware to control and design an ever more complex system.
**Responsibilities**:
- Numerical simulations for the on-chip circuits and its packaging
- Accurate prediction of interface losses
- Accurate prediction of inter resonator couplings
- Design, development and troubleshoot of room temperature hardware (filters, PCBs, etc.)
- Design of the architecture of the upcoming multi-qubits circuits
**Requirements**:
- 5+ years of relevant experience
- Experience with EDA software Ansys HFSS or similar
- Experience in Python programming
- Strong knowledge in transmission line theory and wave propagation
- Knowledge on passive and active RF/MW components
- Experience in cryogenics and/or quantum mechanics
- Professional-level English proficiency, both written and spoken.
**Benefits**:
- 25-day vacation policy (as per French law) + RTT
- Half of transportation cost coverage (as per French law), or yearly allowance for bike enthusiasts
- Competitive health benefits with Helium/AXA
- Meal vouchers with Swile, as well as access to a fully equipped kitchen
- Parental benefits with crèche support
- Flexible remote policy, up to 40 % a month
- Language courses covered by the company
- Mental health support with moka.care
- Subsidized membership with Urban Sports Club
**Recruitment Process**:
- Screening Call with Grace, Talent Acquisition Specialist (30 min)
- Hiring Manager Interview with Felix (45 min)
- Technical Interview/Presentation with the team 60 min)
- Leadership/Fit Interview (45 min)
- Reference Check
You will join of one of the most innovative startups in France at an early stage, to be part of a passionate and friendly team on its mission to build the first universal quantum computer
We love to share and learn from one another, so you will be certain to innovate, develop new ideas, and have the space to grow.
