• Experience measuring or modelling quantum systems.
• Experience developing scientific software for experiment control, numerical analysis or simulation.
• Strong scientific programming and data-analysis skills using Python or an equivalent language.
• A strong understanding of quantum mechanics and qubit control.
• Experience with numerical analysis, parameter estimation, experimental design and optimisation.
• The ability to diagnose complex, system-level performance issues across hardware and software boundaries.
• Clear and concise scientific communication, including confident technical presentation skills.
• A collaborative, ownership-driven approach with strong problem-solving and prioritisation skills.
• Experience working with superconducting qubits and microwave control systems.
• Experience developing, calibrating or experimentally characterising quantum processors.
• Hands-on experience optimising single- or two-qubit gates through pulse-level control.
• Familiarity with randomised benchmarking, gate set tomography or algorithmic benchmarking.
• Experience investigating crosstalk, drift, coherent errors or signal-chain distortion.
• Experience transferring experimental methods into repeatable engineering or operational workflows.
• Knowledge of machine learning or numerical optimisation techniques applied to physical systems.
• Familiarity with control electronics, waveform generation and microwave signal chains.
• Experience with quantum software frameworks such as Qiskit, PennyLane or Cirq.

Responsibilities

• Pushing the performance of quantum processors through advanced control theory, pulse optimisation and rigorous processor characterisation.
• Developing and validating techniques that improve gate fidelity and stability.
• Working across Advanced Product Development, Calibration Engineering, Processor Innovation, Compiler and software teams.
• Diagnosing complex performance challenges and translating successful techniques into repeatable workflows.
• Developing and experimentally validating high-fidelity single- and two-qubit operations.
• Designing, optimising and benchmarking pulse shapes using quantum control, numerical optimisation and experimental techniques.
• Characterising gate error mechanisms, including coherent error, leakage, crosstalk, drift and control-chain distortion.
• Building robust experimental pipelines, data-analysis workflows and performance benchmarks for quantum processors.
• Defining calibration requirements and partnering with Calibration Engineering and Calibration Operations.
• Evaluating new devices with Processor Innovation, providing feedback on gate performance and processor behaviour.
• Transferring new control techniques into OQC's production software stack.
