RF Electronics Engineer for Optical Quantum Interconnects at QphoX, Delft
Job Description
QphoX is hiring an RF Electronics Engineer to help build its technology for scalable, networked quantum computing. The company develops optical interconnects for the control, readout and networking of quantum processors, and this role designs the hardware that delivers and detects RF signals in the SHF band, both at room temperature and inside cryogenic systems. QphoX says an in-depth understanding of quantum networking or quantum computing is not required, which makes this a good entry point for RF engineers who want to move into quantum technology.

How to prepare for this application
- Read a short introduction to microwave-to-optical transduction, to understand why QphoX needs clean RF delivery into electro-optic devices.
- Bring an RF design (simulation plus measured S-parameters) and explain any mismatch between them.
- Revise cryogenic RF basics: attenuation, thermal loads and connector choices.
- Show how you communicate results to people who are not RF specialists.
About QphoX
QphoX is a Delft start-up building optical interconnects for quantum processors: devices that convert microwave signals into optical ones (quantum transduction), so that superconducting quantum computers can be controlled, read out and networked over optical fibre.
