## Description

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., * Perform optical characterization and quality control of single-photon sources

 * Operate and maintain optical setups involving mode-locked lasers, optical fibers, cryogenic systems, and vacuum components
 * Develop and maintain Python software for instrument control, data acquisition, and data processing
 * Develop, automate, and validate measurement procedures to improve process reliability, reproducibility, and throughput
 * Identify sources of measurement variability and contribute to continuous improvement of characterization processes
 * Analyze data and produce systematic reports for internal teams
