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. Planckian is an equal‑opportunity employer. #J-18808-Ljbffr
