Zusammenfassung

MoleSense is seeking a Scientist to lead the development of a sweat chloride sensor for our wearable platform, advancing ion-selective and potentiometric sensors from concept through optimization and validation in real sweat. You will ensure reliability in challenging matrices, tackling selectivity, drift, calibration stability, and sensor lifetime.

You will design sensor-rich hardware, optimize membranes and interfaces, and collaborate across multidisciplinary teams to deliver manufacturable

Qualifikationen

• Hands-on experience developing ion-selective or potentiometric sensors, ideally for chloride.
• Experience with ion-selective membranes, ionophores, reference electrodes, and electrode fabrication.
• Understanding drift, calibration stability, matrix effects, fouling, and reference electrode stability.
• Experience testing sensors in sweat, biofluids, or other complex matrices.

Aufgaben

• Design and manufacture the sensor-rich PCB + corresponding mechanical platform.
• Develop and optimize chloride-selective and reference electrodes for sweat.
• Optimize membrane composition, electrode interfaces, and sensor conditioning.
• Characterize selectivity, sensitivity, drift, stability, reproducibility, and lifetime.
• Validate sensors in artificial and human sweat and investigate matrix effects.
• Establish robust fabrication, calibration, and testing protocols.
• Integrate the sensor with microfluidics, electronics, and the MoleSense wearable platform.
• Troubleshoot failure modes and drive the sensor toward a reproducible, manufacturable design.
• Document development and contribute to IP and product development.
