Join Us at the Forefront of Quantum Computing Innovation 🚀
We are looking for a R&D Engineer - Optical Systems & Single-Photon Source Lithography to support the development of novel designs of Single Photon Sources (SPS) for Quandela’s SPS R&D department.
This position combines advanced optical experiments, hands-on R&D, and manufacturing engineering. The SPSL Engineer will play a key role in the fabrication of new designs of SPSs, that will be further tested by colleagues on characterization testbenches.
The role will have a strong focus on in-situ localization of quantum dots (QDs) at cryogenic temperatures and lithography over the localized QDs with laser writing techniques. The successful candidate will work closely with our SPS R&D team, SPS production team, fabrication engineers, equipment owners, and cleanroom operators to improve performance of the SPSs and successfully transfer R&D advances to our production mainline.
This is a highly hands-on position requiring a strong understanding of optics and semiconductor fabrication, rigorous experimental methodology, and the ability to investigate complex interactions between process parameters and device performance.
Required Qualifications & Experience :
We are looking for someone who combines the mindset of an R&D engineer with the rigor of a manufacturing/process engineer.
The ideal candidate is comfortable developing new systems where all parameters are not yet fully understood, while also being able to transform experimental processes into stable, controlled and documented production workflows.
You should enjoy working directly in the cleanroom, analyzing data, developing Python projects, solving complex fabrication problems, and collaborating across R&D and production teams.
(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 specialises in the production of photon-based quantum computing and cloud solutions, enabling organisations to achieve their quantum transformation.
