3D Integration Engineer H/F
Alice Bob · Aubervilliers (93) · CDI · Télétravail partiel
Publiée le 10 septembre 2026
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 250+ brilliant minds from over 35 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!

Join our Process Integration team, within the Quantum Hardware & Infrastructure department, and help turn cutting-edge QPU designs into physical reality.
This role sits right at the crossroads of nanofabrication, assembly, and scalable QPU design. You'll work hand in hand with teams across our entire hardware organization — from roadmap definition to fabrication, packaging, and validation — to build the 3D integration technologies that will power the next generation of our quantum processors.
Responsabilities
- Explore, identify, and benchmark the most promising 3D assembly technologies for QPUs, evaluated against the demanding constraints of superconducting circuits: material and process compatibility, microwave performance, and cryogenic reliability
- Qualify the integration of QPU building blocks — airbridges, flip-chip bonding, TSV, multi-layer wiring (MLW), superconducting interconnects, and wafer-level assembly — working closely with our fabrication and packaging teams.
- Design and drive integration test plans in collaboration with cross-functional teams
- Build scalable, well-documented integration procedures that will support the company as it grows
- Dive into integration issues and technical anomalies, tracking them down to their root cause and making sure everything stays aligned with our specifications and performance targets
- Be the go-to technical contact for 3D integration with our external foundries, and packaging partners, working alongside our foundry partnerships expert.
Requirements
- PhD or MSc in physics, materials science, electrical engineering, or microelectronics, with strong hands-on cleanroom experience
- 3+ years of demonstrated 3D integration experience, in flip-chip / bump bonding and TSV processing.
- Proven track record of developing and qualifying an integration process brick end to end — from literature survey and test-vehicle design through experiments, data analysis, and go/no-go decision
- Solid grounding in failure analysis and reliability assessment of 3D interconnects: cross-sectioning, SEM, X-ray inspection / tomography, profilometry, electrical test structures
- Understanding of superconducting QPU fabrication and of what cryogenic operation demands from materials and interfaces is a plus
Recruitment process
- Screening Call with Alexandra Talent Acquisition Specialist (30 min)
- Hiring Manager Interview with the Hiring Manager (45 min)
- Technical Interview/Presentation with the Team (90 min)
- Leadership and Fit Interview (60 min)
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.
- Flexible remote policy, up to 40 % a month
- 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
Research shows that women might feel hesitant to apply for this job if they don't match 100% of the job requirements listed. This list is a guide, and we'd love to receive your application even if you think you're only a partial match. We are looking to build teams that innovate, not just tick boxes on a job spec.
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.
