Quantum Measurement Engineer

Planckian

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. Quantum Measurement Engineer

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

What You’ll Be Doing

• 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.

Every Job Has Its Challenges, And This One Is No Exception

• 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.

What We Offer

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

Planckian is an equal‑opportunity employer.
