Internship: Microfabrication for Single-Photon Devices (H2/2026)

About the role

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 datacenters and scalability, positions it to play a key role in the next wave of innovation, and in many strategic and sovereign industrial sectors. Join Us at the Forefront of Quantum Computing Innovation 🚀 Description of the Team/Project This internship offers you the opportunity to join a team dedicated to designing and developing ultra-bright single-photon sources. The project focuses on fabricating innovative optical cavity designs for next-generation single-photon sources. As an intern, you will work in the C2N and IPVF cleanrooms, assisting the team in developing new fabrication recipes for micro-cavities. Your contributions will directly influence the research strategy for next-generation devices and advance the field of single-photon sources. Candidates should have a fundamental understanding of nano/micro processing techniques such as thin-film deposition, lithography, and etching. Experience in electrical, mechanical, or optical characterization of nano- or micro-devices is also desirable. Candidates may commence the internship starting in February, with flexible start dates available thereafter to accommodate individual circumstances. Your Key Responsibilities Conceptualize and perform numerical simulations of the mechanical and optical properties of micro-cavities. Develop and refine fabrication recipes for constructing high-performance cavities. Identify critical fabrication steps that influence device performance and propose improvements. Design, assemble, and operate custom experimental setups for device characterization. Maintain systematic documentation of findings and report results effectively. You are enrolled in a university program that includes an internship period. This should be a Master's Degree (first or second year) or equivalent (not a PhD) program in Physics, Engineering, or related fields You are available full-time for 5 to 6 months You have background in physics, micro-engineering, optics or a related discipline You want to work in an international team and have good English communication skills You are curious, energetic, and love solving problems Experience with Python is a plus Swile Card (meal vouchers) 🍴🛒 50% participation in transportation costs 🚆 Possibility of remote work 💻 Internship Allowance between €1,200 and €1,400 per month 💰 1,5 days off per month, cumulative 🧳 What we also offer A challenging and innovative work environment at the heart of quantum computing. A diverse and collaborative company culture. Opportunities for professional growth and skill development. At Quandala, 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.
