We are seeking an experienced Senior Consultant to support our time-resolved spectroscopy activities on a part-time basis. This role is ideal for a senior scientist with deep hands-on expertise in femtosecond laser systems and streak-camera-based detection system. As Senior Consultant, you will provide specialist technical advice, experimental support, and strategic input. You will work closely with our research team to design, optimize, and interpret time-resolved data.

Your responsibilities

• Advise on the design, setup, alignment, and optimization of ultrafast spectroscopy experiments.
• Support the operation, troubleshooting, and performance optimization.
• Plan and execute time-resolved measurements using streak cameras, including configuration, calibration, data acquisition, and analysis.
• Evaluate experimental data and provide clear technical interpretations, reports, and recommendations.
• Support the selection and integration of optical components, detectors, timing electronics, and synchronization systems.
• Advise internal teams and, where required, external partners on best practices in ultrafast laser and detector technology.

Your profile

• Advanced degree in physics, photonics, optical engineering, physical chemistry, or a related field.
• Several years of hands-on experience with Ti:Sapphire femtosecond laser systems including alignment and troubleshooting.
• Practical experience with streak cameras, including temporal calibration, trigger/synchronization concepts, data acquisition, and interpretation of time-resolved data.
• Strong understanding of ultrafast phenomena, pump–probe spectroscopy, optical delay lines, dispersion management, and time-correlated measurements.
• Experience with optical alignment, beam diagnostics.
• Ability to work independently, communicate complex technical concepts clearly, and deliver high-quality documentation.



We offer

• A flexible part-time contract of 8 hours per week and initially limited to 6 months.
• A collaborative, technically demanding environment with access to advanced ultrafast laser and detection equipment.
• The opportunity to contribute your expertise to challenging research and development projects.
• Flexible working arrangements, with on-site work required for laboratory-based activities.
• Payment is according to TVöD Bund including the usual social benefits
