Electrical Engineer

About Onnes

At Onnes Technologies we are working towards a Quantum Scanning Probe Microscope (qSPM) at cryogenic temperatures to enable single spin resolution imaging of (quantum) materials and biological samples.

We have launched a novel cryogenic nanopositioner product (arQtika) – a dedicated instrument for physics research at milli-kelvin temperatures and the starting component of any low temperature microscope.

Our team is composed of +10 people with various backgrounds in quantum physics, cryogenic engineering, nanotechnology, hardware and more. We work in close collaboration with leading scientists from the Leiden University and the Leiden School of Research Instrumentation.

Role overvieuw

Onnes Technologies is looking for an electrical engineer in the development of electronic products, for example related to the cryogenic nanopositioning systems. These developments range from making electronic designs, testing electronic components and setups, assist in outsourcing of the production, to writing supporting software to operate electronics.
