greenteg AG Tech Stack

Medical-grade thermal sensors and wearable core-temperature monitoring

Appliances, Electrical, and Electronics Manufacturing Rümlang, Zurich 11–50 employees Founded 2009 Public Company

greenTEG manufactures precision thermal sensors (heat flux, laser power detection, calorimetry) for OEM and research applications, alongside CORE, a clinical-grade wearable for continuous non-invasive core body temperature measurement. The tech stack—Embedded C, Zephyr, BLE, Python, TensorFlow, PyTorch—reflects a dual focus: low-level firmware for sensor integration and ML pipelines for temperature prediction algorithms. Active hiring across engineering, manufacturing, and marketing, weighted toward interns and junior roles, suggests they're scaling production and product deployment in parallel.
