Qblox is on the lookout for a Senior RF Engineer to contribute to the development of high-tech control stacks for quantum computers. These control stacks are pivotal in generating the precise analogue signals necessary for the control and readout of quantum bits within quantum computing and networking environments. Operating across frequencies spanning from DC to the microwave regime (up to 18GHz), our signals must exhibit exceptional performance with minimal noise, temperature drift, and interference. As we gear up to scale our systems to thousands of parallel RF channels, your expertise will play a pivotal role in this expansion.

Joining us means becoming part of our dynamic environment, where innovation thrives and every member of our international team makes a direct impact on the product. Collaboration within the team is key, fostering an environment where ideas are shared, creativity flourishes, and solutions are collectively crafted. With the autonomy to explore and innovate, you'll have the freedom to make meaningful contributions and shape the trajectory of our projects. If you're passionate about cutting-edge technology, thrive in a collaborative setting, and you are motivated to make an impact, we invite you to join us.
