We are now looking for Research Scientist, Multi-Layered Wiring to join our Quantum Scaling and Integration team.

You will join our Quantum Scaling and Integration Team, contributing to the development of advanced nanofabrication processes for superconducting multi-layered wiring stacks on 200 mm wafers - a critical technology for scaling quantum processors. In this role, you will work hands-on in cleanroom and characterization environments, collaborating closely with senior scientists and cross-functional teams. You will contribute both to cutting-edge research and to building reproducible, pilot-ready manufacturing capabilities.

Our Quantum Scaling and Integration Team develops advanced technologies for scaling superconducting quantum processors - from TSVs and multilayer wiring to flip-chip integration and full QPU module concepts. We work closely with leading European industrial and academic partners to enable reproducible, wafer-scale fabrication and pilot-ready processes for future quantum computing systems.

As Research Scientist, Multi-Layered Wiring), you will:

• Develop, optimize, and qualify nanofabrication processes for superconducting multi-layered wiring stacks
• Perform thin film deposition, lithography, dry etching (RIE/ICP), and wet processing
• Contribute to process integration, scaling, and transfer across fabrication platforms
• Plan and execute design-of-experiments (DOE) and analyze data for process optimization
• Improve process stability, reproducibility, and wafer-scale uniformity
• Carry out in-line and wafer-level characterization (e.g. SEM, electrical probing)
• Analyze process-performance relationships and support continuous improvement
• Support process control, yield tracking, and KPI definition
• Collaborate with internal teams and external partners in EU projects and research initiatives
• Contribute to documentation, technology transfer, and pilot-scale process development

Who we are looking for:

• For this position, we are looking for a hands-on expert in micro- and nanofabrication with a strong interest in quantum technologies.
• MSc or PhD in applied physics, electrical engineering, materials science, micro/nanotechnology, or similar
• At least 3 years of cleanroom experience (incl. thesis or postdoc work)
• Experience in lithography, etching, thin film deposition, and microfabrication processes
• Understanding of process integration, characterization, and fabrication workflows
• Experience with DOE, data analysis, or process optimization
• Basic programming skills (e.g., Python)
• We also appreciate experience in experience with SPC, yield analysis, or process control methodologies; knowledge of CMP, wafer bonding, or advanced packaging; familiarity with superconducting materials or quantum devices.

As a person, we hope that you are:

• Hands-on, detail-oriented, and focused on data quality and reproducibility
• A proactive problem solver with a continuous improvement mindset
• Able to work both independently and in cross-functional teams
• A clear communicator who can explain technical topics to diverse audiences
• Structured and committed to quality, safety, and documentation
• Curious, open-minded, and motivated to work on new topics
