Pic Characterization Engineer H/F - Quandela

Quandela is a European start up that provides photonic quantum computers that are modular, scalable, energy-efficient and accessible both on the cloud and on premise.

Our team of 85 employees, specialises in the development of both software and hardware solutions for a variety of quantum applications. We offer a wide range of services, from developing the most efficient and brightest single photons sources, to creating algorithms for quantum computers and providing cloud quantum computing solutions.

Quandela plays a pivotal role as a strategic partner in the quantum transformation of industrial sectors such as energy, finance, pharmaceuticals, and transportation. Furthermore, we are esteemed collaborators within the academic and research community.

• Following a successful €50 million fundraising in 2023, we are now scaling up our commercial ventures alongside our ongoing research endeavors.
• Quandela has been chosen to participate in the French Tech 2030 program, which aims to bolster French companies pioneering groundbreaking innovations.

AboutQuandela:

Quandelais a Europeandeeptechscale-up building modular, scalable and energy-efficientphotonicquantum computers.

With more than 140 people, we develop our own hardware technologies, from single-photon sources to photonic integrated circuits (PICs), and make them accessible via cloud andon-premisesystems.

At the core of our processors are Photonic Integrated Circuits (PICs): compact optical chips that route and manipulate single photons to perform quantum operations at scale.

Aboutthisposition:

Youwilljointhe Integrated Photonicsteamin Massy,workingat the interfacebetweendesign, fabrication, and systemintegration.

As the number and complexity of our PICs increase, we are expanding our characterization capabilities to support both device development and structured qualification.

We are looking for an experimental profile with hands-on experience in integrated photonics characterization, typically gained through 2-3+ years of relevant experience and/or a PhD with a strong experimental component.

You will ensure reliable and rigorous characterization of PIC devices, from measurements to data analysis, while taking ownership of characterization campaigns and contributing to workflow improvements.

This is not a pure research role. It is an experimental and operational position within a growing hardware platform, with strong laboratory ownership at its core.

Join a growing quantum hardware company and contribute directly to scaling photonic quantum technologies from device characterization to system integration.

- Play a key role in the characterization and qualification of photonic integrated circuits
- Contribute to improving measurement reliability, reproducibility and efficiency as the platform scales
- Work within a multidisciplinary team at the intersection of design, fabrication, packaging 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 background is slightly different from what is described above but you bring strong experimental experience in integrated photonics, we still encourage you to apply !
