Quantum Measurement Engineer

Overview

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. About the role

In this role, you will work at the intersection of quantum physics, microwave engineering, cryogenics, and software, enabling reliable characterization and operation of scalable quantum processors. You will play a key role in turning experimental hardware into a robust, measurable, and reproducible quantum system. What You\ll Do

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 and compare results with theoretical models and simulations 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 +5y 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 What We Offer

Competitive salary Stock options Flexible working hours with hybrid working Ego-free, merit-based environment Planckian is an equal-opportunity employer.
