Electrochemical Sensor Development for Medical Devices
The Product Care Team at Roche Diagnostics in Rotkreuz, Switzerland, is seeking a skilled Sensor Development Engineer to join their team. This role involves developing, characterizing, and optimizing electrochemical sensors for medical devices used in In-Vitro Diagnostics (IVD) testing.
The team focuses on measuring various parameters such as gases (O2 & CO2), electrolytes (pH, Na+, K+, Ca2+ & Cl-), and metabolites (Glucose & Lactate) in whole blood. To achieve this, they employ electrochemical, optical, and enzymatic measuring principles. The successful candidate will develop new sensor methods based on theoretical foundations and apply them to create innovative sensors.
Main Responsibilities:
* Address product care topics related to sensor production, including deviations, root cause analysis, and risk assessment.
* Implement changes based on fundamental principles, experimental data, and simulation models, ensuring seamless integration into new and existing products.
* Independently plan, execute, evaluate results, and document work within development, product care, and operations support frameworks.
* Conduct lab tests and analyses using various characterization methods (e.g., electrochemical analysis, IR, SEM) and collaborate with a multidisciplinary team to generate required data and documentation.
* Take ownership of equipment and develop new tools, methods, and processes to evaluate sensors.
* Provide scientific expertise and practical knowledge to resolve technical questions arising in development and production of complex electrochemical sensors and electrodes.
* Interact with quality, operations, V&V, and business teams to support design and material changes.
* Depending on project needs and product care situations, contribute to sensor development activities in new development projects.
Requirements:
* Bachelor or master's degree in chemistry, physics, materials science, or electrical engineering from a recognized university.
* In-depth understanding of materials (glasses, metals, polymers, and other chemicals) and their interactions with sensors and biological samples.
* Passion for studying, testing, and improving electrochemical/optical (bio)sensors and understanding their behavior and associated material properties.
* Experience working in highly regulated environments.
* Ability to work in multidisciplinary development teams with diverse backgrounds.
* Excellent communication skills, with English as the primary language; German is an advantage.
* Proficiency in data acquisition, processing, and analysis using tools like Matlab, Excel, MiniTab, R, and Python.
* Strong problem-solving skills, with the ability to adapt to new challenges and priorities.
* First-hand experience in producing industry is an asset.
