Qilimanjaro Quantum Tech is seeking a Senior Quantum Calibration Engineer to support the calibration, control, and characterization of superconducting quantum processors. This role focuses on the experimental operation of multi-qubit devices, with work expected to be distributed between transmon- and fluxonium-based quantum architectures.
We are particularly interested in candidates with strong experience in transmon-based systems, complementing our existing expertise. The ideal candidate is motivated to improve the performance, stability, and reproducibility of established quantum hardware, while contributing positively to a collaborative and technically rigorous R&D environment.
🫡Key Responsibilities:
- Calibrate and operate multi-qubit superconducting quantum processors based on established digital or analog architectures.
- Develop, implement, and maintain calibration procedures for qubit control, readout, and multi-qubit operations.
- Perform systematic characterization of device performance, stability, and crosstalk.
- Carry out measurements on both transmon- and fluxonium-based superconducting circuits.
- Collaborate closely with design, fabrication, integration, and software teams to ensure efficient experimental workflows.
- Document calibration procedures, experimental results, and best practices to support reproducibility and scalability.
📝Minimum requirements:
- PhD in Physics or a closely related field, with a strong focus on superconducting quantum circuits.
- Demonstrated experience in quantum measurement and calibration of transmon qubits.
- Strong analytical and problem-solving skills, with a systematic approach to experimental work.
- Excellent communication and documentation skills.
🤹Preferred Skills:
- Strong experience calibrating and measuring multi-qubit transmon-based quantum processors.
- Experience measuring fluxonium-based superconducting circuits.
- Experience with tunable couplers.
- Familiarity with calibration workflows for digital quantum architectures.
- Proficiency in Python or similar programming languages for experiment control and data analysis.
- Experience with designing and/or fabricating superconducting devices.
- Ability to contribute to mentoring, knowledge transfer, and healthy team dynamics.
💻Additional Information:
The main working location is Barcelona, with a significant onsite presence expected and some flexibility for remote work during the week. Occasional work at other locations where quantum systems are installed may be required.
