Pic Design Engineer H/F - 92

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.

About this position:

You will join the Integrated Photonics team in Massy, composed of senior engineers, PhDs, and research interns working acrossdesign, characterization, and packaging of our PICs.

The team owns the full design cycle of our photonic circuits - from simulation and layout to foundry collaboration and performance feedback. Fabrication is outsourced, but simulation depth, architectural choices, and design-for-manufacturing decisions are fully internal.

You will design andoptimizekey building blocks of our PIC platform, translating system requirements into robust and manufacturable layouts that support the evolution of our processors.Working closely with characterization, you will iteratively refine your designs based on fabrication variability and experimental feedback.

The coming year is strongly design-driven, with a focus on improving robustness against fabrication variability, increasing integration density, and preparing architectural evolutions for future scalable quantum processors.

Why this role matters:

What you design today directly shapes the scalability, stability, and performance of tomorrow's photonic quantum processors.

Your work directlyimpactshow efficiently our circuits scale, how resilient theyremainunder fabrication variability, and how quickly research concepts become reliable hardware.

AsQuandelagrows, this role helps shape not only components, but also the design methodologies and standards that will support larger-scale andfault-tolerantquantumarchitectures.
