Simon Gröblacher

This postdoctoral project develops optomechanical sensors for infrared sensing and imaging within a collaborative framework linking TU Delft and AMOLF . The work is embedded in QSTeM , a testbed for mechanical sensing led by Letizia Catalini , where sensors are designed, benchmarked, and developed together with academic and industrial partners. The researcher will work across the full sensor-development chain, combining device and material engineering , nanofabrication , optical characterization , and measurement protocols. A central part of the project is the design and fabrication of nanostructured optomechanical devices , with particular interest in how material properties, thermal transport, and device geometry affect performance. The aim is to improve sensor sensitivity, stability, reproducibility, and robustness while advancing optomechanical sensing toward practical applications. Beyond the initial infrared-sensing focus, the project leaves room to explore additional sensing modalities and device concepts as new opportunities arise. The postdoc will also contribute to measurement and benchmarking services for external partners, supporting QSTeM as a testing facility and working closely with collaborators on device characterization. The position is based in Delft, primarily at the QSTeM testbed, with day-to-day interaction with the joint TU Delft and AMOLF teams. The postdoc will also be part of the Gröblacher group in the Department of Quantum Nanoscience at TU Delft, with access to mentoring, group activities, and advanced cleanroom infrastructure for next-generation nanostructures. The advert emphasizes an interdisciplinary, application-driven environment where fundamental research and real-world sensor development meet.
