Job Summary
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. 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. 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 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 yield improvement.

What You Will Do
- Perform optical and electrical performance characterization of packaged TFLN PICs using e.g. tunable lasers optical spectrum analyzers (OSAs) vector network analyzers (VNAs) RF probes and high-speed oscilloscopes
- Execute developed test procedures for advanced lab setups ensuring measurement accuracy and repeatability across characterization runs
- Document measurement datasets test conditions and results to the standard required for design validation and root cause analysis workflows
- Maintain daily lab environment equipment readiness calibration status and safe handling of optical fibre laser sources and RF instrumentation
- Collaborate with senior PIC DC experts and cross-functional team members to align on test priorities flag anomalies and support continuous improvement of characterization workflows
- Support the availability of packaged PICs for product evaluation by delivering characterization results within agreed lead times
Your profile
Required:
Nice to have:
- . or completed vocational training in optoelectronics telecommunications physics electrical engineering with photonics specialization or a closely related field
- Hands-on experience with optical fiber and laser handling in a lab environment including alignment coupling and safe operation; gained through an internship thesis work lab course or equivalent academic project
- Foundational knowledge of integrated photonic components and their operating principles e.g. waveguides modulators couplers and detectors sufficient to interpret characterisation results in context
- Solid grounding in lab documentation practice and measurement reproducibility you understand that consistent traceable data is the output not a by-product
- Very good English (written and spoken) or very good German with working English
Nice to have:
- Hands-on experience across a broader instrument set: VNAs high-speed oscilloscopes OSAs RF probes and tunable lasers
- Python programming for measurement automation data acquisition or analysis
- Working knowledge of RF measurement principles signal integrity impedance matching S-parameter basics
- Knowledge of instrument control frameworks (SCPI VISA GPIB or equivalent)
- German proficiency (if English is your primary language)
- Any prior exposure to TFLN photonics specifically
Why us
- Grow at the frontier:Work on photonic integrated circuit technologies with few industry precedents every measurement you master and every problem you solve builds expertise that is genuinely rare
- Learn from the best:Work directly alongside senior experts in photonics electronics and packaging in a hands-on lab environment structured guidance from day one with room to grow fast
- Real work real impact:Your characterization data feeds directly into design decisions and production readiness your contribution matters from your first week
