Junior PIC Characterization Engineer (f/m/d)

Your mission

Location: Stuttgart, Germany
Type: Permanent employment, full-time
Work mode: On-site, 1 remote day per week


The future of AI computing builds on light. Q.ANT is building photonic processing systems that compute with light – a scalable, energy-efficient alternative to transistor-based architectures for next-generation AI and HPC applications. Q.ANT’s photonic integrated circuits (PICs) are at the heart of this technology, and the precision with which they are characterized determines how fast they reach production.

You will perform electrical and optical characterization of packaged Thin-Film Lithium Niobate (TFLN) PICs for Q.ANT’s PIC technology. Working alongside senior experts in a hands-on lab environment, you will execute structured test workflows, deliver high-quality measurement data, and maintain the lab conditions that make reproducible, reliable results possible – directly supporting design validation, root cause analysis, and y...
