Senior Nanofabrication Engineer – SNSPD Technologies

The company seeks a Senior Nanofabrication Engineer in Geneva to fabricate SNSPD devices, optimise cleanroom processes, and support the technology roadmap through hands-on R&D and continuous improvement.

This position sits within the SNSPD team in Geneva, where the primary focus is the fabrication of SNSPD devices and the ongoing refinement of nanofabrication processes within a cleanroom setting. The role involves executing process flows and producing R&D wafers that act as prototypes for device development, directly supporting the delivery of the technology roadmap by transferring validated processes toward production.

Responsibilities

• Execute and optimise nanofabrication process flows to produce SNSPD wafers and prototype devices for R&D activities.
• Perform optical and e-beam lithography, thin-film deposition, and etching processes.
• Fabricate and deliver wafers to the testing team to enable device characterisation and validation.
• Monitor process stability, identify opportunities to improve yield and reproducibility.
• Support the qualification of new materials, tools, and process steps through structured experimental work and data analysis.
• Ensure fabrication outputs are aligned with device and roadmap requirements.
• Contribute to the continuous optimisation and documentation of fabrication procedures.
• Drive process improvement, data analysis, and cross-team collaboration to enhance yield, reproducibility, and fabrication standards.

Requirements

• Bachelor’s or Master’s degree in Physics, Engineering, Materials Science, or a related field.
• At least five years of hands-on cleanroom experience in nanofabrication.
• Fluency in English.
• Rigorous, reliable, and detail-oriented with a practical mindset.
• Ability to work both independently and collaboratively in a fast-paced R&D environment.
• Strong communication skills.

Nice to have

• Familiarity with thin-film deposition and characterisation techniques such as sputtering, evaporation, SEM, and AFM.
• Strong interest in experimental work and a process-oriented approach to problem solving.
• French language skills are considered an advantage.
• Over eight years of hands-on cleanroom experience in nanoffabrication.
• Experience working across a range of nanofabrication facilities and environments.

What the company offers

• A role at one of the fastest growing and most exciting Quantum companies in the world.
• A competitive compensation scheme, benefits package and equity plan.
• Flexible work models that let you balance your life, your family, and your career.
• Ongoing training and development to keep your skills sharp and your growth on track.
• A career development plan within the IonQ group’s companies.
• A dynamic, close-knit environment where you collaborate with a global team of experts.
