Planckian is developing the core technology to power utility-scale quantum computers.
Il suo CV è pronto? Se sì, e se è convinto/a che questo sia il ruolo giusto per lei, si candidi il prima possibile.
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

Every job has its challenges, and this one is no exception. While many companies gloss over them, we believe in being upfront:
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.

We're not looking for perfection, we're looking for people who are ready to grow through the hard parts and help us build something that lasts. xrdbqlu
