Senior PIC Characterization Engineer - TFLN / High-Speed (f/m/d)

What You Will Do

• Design and execute high-speed (GHz-regime) characterization routines for TFLN PICs and photodiodes; perform experimental verification and statistical analysis to extract key performance parameters
• Define, design, build, and develop optical and RF test setups - including probe-station configuration, calibration, routines, and continuous optimization
• Develop Python, LabVIEW, and MATLAB tools for measurement automation, data acquisition, and analysis
• Contribute to the full photodiode-PIC hybrid integration lifecycle - from concept and design coordination through assembly, validation, and packaging
• Feed performance insights back to design and manufacturing; propose new components and optimization strategies for the technology and product roadmap
• Schedule and prioritize characterization campaigns in line with project milestones and R&D priorities; coordinate external suppliers, service providers, and research partners
• Mentor and guide junior engineers and technicians in device testing, data acquisition, and analysis
• Ensure adherence to lab safety standards and equipment-handling protocols, and maintain rigorous documentation of methods, code, and results

Your profile

• Ph.D. or Master’s degree in electrical engineering, photonics, or a related field
• 5+ years of directly relevant experience in industry or research, including at least 1 year in GHz-regime high-speed photonic device testing
• Deep understanding of LNOI (lithium niobate on insulator) device physics and applications, including high-speed modulation, detection, and RF signal integrity; hands-on TFLN experience is a strong plus
• Proven experience in photodiode characterization and hybrid photonic-electronic integration
• Strong hands-on experience with high-speed instrumentation: VNAs, high-speed oscilloscopes, optical spectrum analyzers, RF probes, and tunable lasers, including calibration methods for optical and RF systems
• Solid programming skills in Python required for measurement automation and data analysis, LabVIEW and MATLAB skills are advantageous
• Practical experience in PIC testing, optical and RF probe-station measurements, optical alignment, and optoelectronic system bring-up
• Experience mentoring or supervising junior engineers in lab environments
• Strong communicator who coordinates effectively across cross-functional teams and external partners, and influences technical direction without formal authority
• Structured, problem-solving mindset with ownership of experimental outcomes
• Fluent English skills are a must; German is beneficial
