Workplace: on_site
Department: Products - Semiconductor Sources Production
Quandela stands as a global leader in quantum computing, driven by groundbreaking technology and a strategic vision for scaling quantum solutions. The company’s unique ability to offer both hardware and software solutions, along with its commitment to build energy efficient quantum processing units that scale, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors.
With a team of more than 140 people, we develop our own hardware and software stack, from semiconductor quantum emitters and photonic processors to quantum control systems and quantum algorithms.
Our ambition is to build large-scale fault-tolerant quantum computers capable of solving problems beyond the reach of classical computation using Quandela's cutting-edge quantum dot technology.
Achieving this vision requires not only advances in photonic quantum computing, but also the development of scalable spin-photon interfaces, distributed entanglement capabilities and future SPOQC (Spin-Optical Quantum Computing) architectures that will enable modular and fault-tolerant quantum systems.

Role overview:
We are looking for an Optical Test and Automation Engineer to strengthen our team responsible for the characterization and benchmarking of single-photon sources.
This role combines hands-on optical quality control of quantum emitters with the continuous improvement and automation of characterization processes. You will develop, validate, and maintain instrument-control, data-acquisition, and automated measurement procedures, helping to transform optical characterization into robust, repeatable, and scalable quality-control processes.
The position has a strong focus on optical spectroscopy, measurement of the quantum properties of semiconductor quantum dots embedded in microcavities, as well as development and optimization of automated test and measurement routines.
You will work in a cleanroom environment alongside optical, nanofabrication, and production engineers to industrialize our optical characterization processes while maintaining high measurement quality, reliability, and throughput.
Key responsibilities
Required
Master's degree or PhD in optics, photonics, quantum optics, experimental physics, or a related field
Ideally, between 2 years of professional experience after a Master's degree and 2 years of experience after a PhD
Nice to have
(This process is provided for guidance only and may evolve depending on the roles)
At Quandela, we believe that the strength of our team is the plurality of experiences, perspectives, and journeys. We are committed to building a respectful, inclusive, and welcoming work environment. All applications are welcome.

Quandela builds full-stack photonic quantum computers in France, including on-premises MosaiQ hardware and cloud access to its processors. It uses semiconductor quantum-dot single-photon sources to create bright, indistinguishable photons that act as optical qubits, with Perceval, an open-source Python framework, for simulating and programming photonic circuits, and Prometheus, a standalone single-photon source for research labs. The company differentiates itself by offering end-to-end hardware, software, and services—from production in its own facilities to cloud access and an acceleration program that guides clients from use-case exploration to hardware delivery. Its goal is to help clients achieve practical quantum advantages across industries such as cybersecurity, energy, finance, logistics, chemistry, and pharmaceuticals.
