We are Qubitrium, a young and dynamic deep-tech company. We offer solutions and services in quantum internet, communication and quantum sensing. We are experts in our domain and committed to make the difference. 

We have offices in Istanbul and Delft. Are you the next to embark on this journey together with us? Then we invite you to join our company.

We are looking for a Senior Analog Design Engineer to design the low-noise, high-precision electronics that drive our quantum entanglement hardware. You will be responsible for the physical layer of our technology that bridges the quantum components and digital logic.

Your main responsibilities include:

• Design and implement active quenching circuits and gating electronics to minimize dead time and afterpulsing in Silicon and InGaAs avalanche photodiodes.

• Develop high-speed converters to translate picosecond-scale avalanche currents into clean digital pulses.

• Design stable, low-ripple high-voltage bias supplies to optimize photon detection efficiency.

• Design ultra-low noise current drivers especially for laser diodes and to ensure stable optical output.

• Develop analog feedback loops (PID) and piezo drivers.

• Implement precision thermoelectric cooler controllers for narrowly stabilizing temperatures of components.

• Lead the layout of PCBs dealing with sensitive analog signals alongside high-speed digital signals.
