Scientific Assistant to Engineer Next-Generation Neural Interfaces

Location: 100%, Zurich, fixed-term

The brain is an incredibly complex system, comprised of billions of neurons that continuously interact with one another. Capturing this network activity at the single-cell level from multiple brain regions is crucial for understanding how the brain executes its various cognitive functions. Current methods for interfacing with the brain have limitations in temporal resolution, biocompatibility, or the capacity to access deeper brain areas. To address these challenges, we have developed Ultra-Flexible Tentacle Electrodes (UFTEs), which feature fibers an order of magnitude smaller than human hair (2.4 µm x 7 µm cross-sectional area). These electrodes enable us to record single-unit activity from multiple brain regions in freely moving rodents with nearly year-long stability. Unlike existing rigid electrodes, UFTEs are not recognized by the brain's immune system, providing a superior signal-to-noise ratio compared to state-of-the-art flexible electrodes (Yasar & Gombkoto et al., Nature Communications, 2024).

Project Background

While we have successfully demonstrated in vivo validation of UFTEs, further developments are necessary for their widespread adoption as a sophisticated research tool within the neuroscience community. We have received a project grant from Innosuisse to enhance the user-friendliness and scalability of UFTEs, incorporate multimodal recording and stimulation capabilities, and adapt these technologies for non-human primate studies. The ultimate objective is to bring UFTEs to market as an advanced research tool.

Job Description

• Developing a new MEMS-based scalable assembly and insertion system for Ultra-Flexible Tentacle Electrodes and supporting its in vivo validation
• Establishing new protocols for characterizing UFTEs and improving their long-term stability
• Designing and conducting regular cleanroom microfabrication of UFTEs

This is a 1.5-year position that can start in April 2026 (exact date by agreement). Follow-up positions may be available depending on interest and funding.

Profile

• Swiss citizen/permanent resident or EU/EFTA national
• Master's degree in Mechanical Engineering, Microsystems Engineering, Materials Science, Physics, Biomedical Engineering, or a related field
• Required skills/knowledge: Micro- or nanofabrication and characterization in a cleanroom environment, 2D and 3D design (AutoCAD, SolidWorks, etc.), prototyping, basic electronics and circuit design skills, assembly/manipulation of microscopic components
• Ability to work independently on a project until its successful completion, establishing new fabrication/testing protocols based on literature review
• Excellent problem-solving skills
• Strong communication skills (both verbal and written) and the ability to work collaboratively in a team
• (Optional) Previous experience working in FIRST Lab (ETH Zurich) and current access would be a significant advantage

Workplace

Join our dynamic and interdisciplinary environment at ETH Zurich, one of the world’s leading universities in science and technology. You'll have the opportunity to work at the forefront of neural implant technology, contributing to its market readiness for commercialization.

We Offer

• An opportunity to explore the exciting fields of neural interfaces and neuroscience in a highly interdisciplinary environment.
• Experience throughout the full lifecycle of device development, from design and construction to observing in vivo brain-machine interface applications.
• Access to a robust network of neuroscientists and engineers at the Institute of Neuroinformatics, Neuroscience Center Zurich (ZNZ), and collaborating labs worldwide.
• Flexibility in working hours and location; while most of your time will be split between the lab and cleanroom, we support remote work for mechanical/electrical design activities.

Commitment to Diversity and Sustainability

ETH Zurich fosters an inclusive culture that values diversity and promotes equality of opportunity. We nurture a working and learning environment in which everyone's rights and dignity are respected. Sustainability is a core value; we continuously strive for a climate-neutral future.
