Your work will directly contribute to the performance and scalability of quantum computing systems.

## Main Duties and Responsibilities

* Qubit Calibration: Calibrate and fine-tune spin qubit systems to optimize gate fidelities, coherence times, and overall device performance.
* System Optimization: Collaborate with quantum hardware teams to improve qubit initialization, readout processes, and error-correction techniques.
* Hardware & Software Integration: Work closely with cross-functional teams to ensure smooth integration of quantum hardware with control electronics and software.
* Algorithm Development: Develop and implement automated calibration routines and control sequences using advanced programming techniques to enhance qubit stability and system robustness.
* Problem Solving: Address challenges such as qubit decoherence, charge noise, and crosstalk using experimental techniques and data-driven approaches.
* Software Tools: Utilize and develop software tools in Python for data analysis, qubit control, and calibration automation. Collaborate using version control systems (e.g. Git) to manage and document code and project development.
* Documentation & Reporting: Maintain detailed records of calibration processes, results, and device performance, and present findings to technical teams.
* Research & Innovation: Contribute to research efforts aimed at improving the scalability and efficiency of quantum computing hardware.

## Experience and Qualifications

**​Required**

* Education: [M.Sc](http://M.Sc). or Ph.D. in Quantum Physics, Electrical Engineering, or a related field.
* Experience: Hands-on experience with calibrating and measuring solid state quantum devices, such as spin qubits or superconducting qubits.
* Technical Skills:

  + Strong background in quantum mechanics and semiconductor device physics.
  + Proficiency in cryogenic systems or low-temperature experiments.
  + Experience with RF and microwave electronics for qubit control and signal generation.
  + Expertise in Python for data analysis, control automation, and experimental optimization.
  + Familiarity with Git or other version control systems for collaborative software development.
  + Knowledge of quantum control software, and experience working with integrated hardware-software systems.
* Problem-Solving Skills: Ability to diagnose and resolve complex issues in quantum devices.
* Communication: Excellent technical writing and presentation skills for sharing results with internal teams.

**​Desired Experience**

* Prior experience with spin qubit systems or semiconductor-based quantum technologies.
* Understanding of quantum error correction and multi-qubit architectures.
* Familiarity with scalable quantum computing hardware and quantum information theory.
* Experience with software development best practices, such as version control, code documentation, and collaborative coding.
