Single-Photon Source Fabrication Engineer

Quandela is a leader in the development and commercialization of quantum computers based on the manipulation of single photons.

We are seeking a full-time (permanent contract) Fabrication Engineer to participate in the optimization of Quandela's single-photon sources.

We work with quantum dots in micropillar cavities and you will join the research team responsible for improving the brightness and indistinguishability of the devices.

You will contribute to the research roadmap of Quandela by improving the micropillar fabrication process and designing new devices. In addition, you will operate and optimize optical setups to characterize the influence of the fabrication on the optical properties of the microcavities. Your results will influence the research strategy for next-generation production devices as well as advancing the field of single-photon sources.

Responsibilities

· Participate in the production of Quandela’s single-photon sources.

· Identify and improve fabrication steps impacting device performance.

· Conceptualize and test new designs for improved SPS brightness and indistinguishability.

· Build and operate custom setups to characterize micropillar cavities at cryogenic temperatures.

· Implement a research roadmap and ensure timely delivery of outcomes.

· Systematically document the results and report your findings (including patents, scientific publications and participation in international conferences).

· Collaborate with the production teams to transfer successful results.

Requirements

You must be highly skilled in nano-micro processing techniques (thin film deposition, lithography, etching, etc.) and have experience with electrical and optical characterization of semiconductor heterostructures.

What are your main qualifications and experience ?
