Make sensor technology accessible – and customers happy!

Passionate about oxygen sensor technology, exciting applications in the field of natural sciences like (marine) biology, life sciences, microfluidics, aquatic ecology (respirometry, photosynthesis), biogeochemistry or chemistry, and love it when things run smoothly and solution-oriented? Then join our dedicated technical sales team and help implement complex sensor solutions in a clear, structured, and customer-friendly manner.

You’ll work closely with our end-customer sales team as well as our developers and administrative colleagues – acting as the bridge between customer inquiries, consulting, and after sales support.
