Pic Characterization Engineer H/F Quandela

Join one of the fastest-growing quantum hardware companies in Europe and play a central role in scaling photonic quantum technology from prototype to structured production.

- Contribute directly to the qualification and reliability of photonic quantum chips as production volume increases
- Grow within a hardware platform transitioning from R&D experimentation to structured batch-level industrial workflows
- Work in a passionate, multidisciplinary team at the intersection of design, fabrication and system integration

- Competitive compensation aligned with your experience and level of responsibility
- Company savings plan
- 100% health coverage (Alan)
- Transport reimbursement or mobility bonus

- Swile meal vouchers
- Access to Gymlib

If your experience exceeds the scope described above, we still encourage you to apply - we are open to strengthening our characterization capabilities as the platform scales !
