Job description

Senior Analog Design Engineer

Location: Delft, Netherlands

Start date: As soon as possible

About Us

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.

Job Description

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.

What We Are Looking For

• BS, MS or PhD in Electrical Engineering or Physics.
• 5+ years of hands‑on experience in analog circuit design.
• Track record of discrete circuit design, SPICE simulation, characterization and debugging.
• Experience handling fast transients (sub‑nanosecond rise times) and high‑bandwidth signal chains.
• Experience specifically with avalanche photodiodes and FPGA interfacing is desirable.
• Fluent in English, written and spoken.

What We Offer

• A competitive salary aligned with your skills and experience, and an additional 8% annual holiday bonus.
• Opportunities to work on international R&D projects and be part of the quantum revolution.
• A chance to join a leading quantum innovation hub (House of Quantum, Delft), and a young, energetic team of highly skilled physicists, engineers, and industry experts.
• Plenty of room for your own initiatives and ideas, with opportunities to develop yourself at the cutting edge of technology.
• Company sponsored social events.

Please note that this role will be based out of our Delft office. In order to realize our goals, we are an office‑first company and encourage in‑person collaboration. Therefore, we do not offer remote‑only roles.
