Quantum Measurement Engineer

Job Details

Planckian is developing the core technology to power utility‑scale quantum computers. By design, our chip architecture decouples control lines from qubit count, removing a key bottleneck in scaling. It combines the proven reliability of superconducting circuits with a breakthrough approach to qubit control, paving the way for quantum computers capable of solving the world’s most challenging problems.

We are seeking a Quantum Measurement Engineer to design, implement, and optimize high‑fidelity measurement and control of superconducting qubits.

Responsibilities

• Design, implement, and optimize qubit readout and control chains for superconducting quantum processors;
• Develop measurement protocols for qubit characterization (T₁, T₂, Ramsey, echo, RB, readout fidelity, crosstalk, etc.);
• Optimize signal‑to‑noise ratio and measurement fidelity under realistic hardware constraints;
• Develop and maintain experimental control software (Python‑based stacks, FPGA or AWG integration);
• Analyze experimental data;
• Collaborate closely with device physicists, fabrication teams, and system engineers to improve hardware performance;
• Contribute to scalable measurement architectures and automation for large‑qubit systems;
• Document experimental procedures and results clearly for internal and external communication.

Requirements

• PhD or MSc in Physics, Applied Physics, Electrical Engineering, or a related field;
• At least +5 years of strong hands‑on experience with superconducting qubits or closely related quantum hardware;
• Practical experience with microwave engineering (GHz electronics, IQ mixers, amplifiers, VNAs);
• Solid understanding of quantum measurement theory and qubit decoherence mechanisms;
• Experience operating cryogenic systems, especially dilution refrigerators;
• Proficiency in Python for experiment control and data analysis;
• Familiarity with lab automation and measurement frameworks;
• Ability to debug complex experimental setups across hardware and software layers.

Challenges

• You’ll face tough situations, especially the classic challenge: people problems. Navigating human dynamics can be tricky and requires patience and empathy;
• Some work is unglamorous, but building a great company means rolling up your sleeves. From strategic decisions to hands‑on grunt work, everyone contributes to the heavy lifting.

Benefits

• Competitive salary + benefits;
• Stock options;
• Flexible working hours with hybrid working;
• Ego‑free, merit‑based environment.
