Stuttgart, Baden-Württemberg, Deutschland Q GmbH Vollzeit
Your mission

This role is enabling next generation analysis and characterizations of thin-film lithium niobate (TFLN) structures, photonic integrated circuits (PICs) and modules operating in the GHz regime. System-on-chip measurements and electrooptical characterizations for photonic-modules enable the development, integration and verification of essential building blocks for our core products and demos. This role is combined with responsibilities for PIC labs.

Key responsibilities:

  • Deliver high-precision performance data enabling design validation, root cause analysis, and manufacturing yield improvement.
  • Shorten design-to-validation cycle time through efficient setup automation and streamlined test methodologies.
  • Enhance product performance and manufacturability by providing clear, data-driven recommendations to design and process teams.
Your profile

Education: Master's or PhD in Photonics, Electrical Engineering, Applied Physics, or a related field.

Experience:

  • ≥3 years in photonic device characterization, with ≥2 years in GHz-regime high-speed
    testing.
  • Proven track record in setting up and optimizing optical & RF probe stations for PIC measurements.
  • Experience mentoring or supervising students or junior engineers in lab environments.
Technical Knowledge:
  • Thin-film lithium niobate device physics and applications.
  • SEM and microscopy techniques.
  • High-speed optical modulation, detection, and RF signal integrity principles.
  • Photodiode characterization principles.
  • Measurement instrumentation (VNAs, high-speed oscilloscopes, optical spectrum analyzers, RF probes, tunable lasers).
  • Calibration methods for optical and RF systems.
Tools & Processes:
  • Automation scripting (Python, LabVIEW, MATLAB).
  • Data acquisition systems and post-processing workflows.
  • Familiarity with cleanroom processes and device fabrication steps.
Languages: Fluent in English; proficiency in German or another European language is a plus.Why us?
  • Make growing demand in compute and sustainability go hand in hand
  • Work on leading edge photonic AI acceleration technologies.
  • Collaborative and innovative work environment.
  • Own your work from day one and fast-track your professional growth.
  • Work alongside a passionate, international, cross-functional team of experts.
  • Collaborate closely with the company's founders and core leadership team.
