Join Our Team as a Hardware Validation Engineer at Qblox!

At Qblox, we operate at the frontier of the quantum revolution, we are the leading provider of scalable and modular quantum control stacks that generate the analogue signals essential for controlling and reading out qubits in next-generation quantum computing and networking systems. Our work directly contributes to shaping the future of this revolutionary technology.

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.

Your experience as a Hardware Validation Engineer will play a pivotal role in the expansion to our next generation system.

Our R&D team tackles complex challenges, and you will test, characterize, validate and debug high-performance electronic hardware, working at the intersection of high-speed digital, RF, and ultra-low-noise measurement systems.

This role requires deep expertise in circuit analysis, experience with automated test frameworks

and mastery of lab equipment.

Joining Qblox means becoming part of a dynamic, international team where innovation thrives. Collaboration is at the heart of our culture — ideas are shared, creativity is encouraged, and solutions are crafted together. You will have the autonomy to explore, experiment, and make meaningful contributions that directly impact the trajectory of our projects.

If you want to push the boundaries of technology, thrive in a collaborative environment, and play a key role in building the next generation of quantum computing hardware, we’d love to hear from you.
