ML Engineer for Automated Quantum Calibration

Silicon-Quantum-Computing; Sydney; On-site; AUD 120,000 - 170,000; Full time

Job summary

Silicon Quantum Computing (SQC) in Sydney is seeking a Machine Learning Engineer for Automated Calibration Services. You will build models to predict qubit drift, optimise calibration routines, and validate decisions against real-device data.

Based at our Sydney facility, you’ll work with physicists and engineers to drive calibration with uncertainty-aware decisions, aiming to minimize device time while maintaining reliability.

Qualifications

• 4+ years applying machine learning in production, ideally where the output drives a physical system.
• Strong Python and the scientific stack: NumPy, SciPy, pandas, scikit-learn, and PyTorch or JAX.
• Sequential decision-making under expensive experiments: Bayesian optimisation, Gaussian processes, active learning or bandits.
• Time series modelling, and anomaly or drift detection on real telemetry.
• Uncertainty quantification, and knowing what a calibrated confidence interval is worth.
• Validating models where data is scarce, correlated and non-stationary, and recognising an implausibly strong result.
• Deploying models into a loop with monitoring, alerting and a fallback path.
• Working with scientists on a problem where the domain knowledge is theirs and the automation is yours.
• Numerical work: curve fitting, parameter estimation and optimisation.
• Git workflow, code review and testing applied to research code.
• Clear technical writing

Responsibilities

• Build models that predict qubit drift and device health, and turn those predictions into decisions about which routine runs and when
• Replace exhaustive parameter sweeps with sequential optimisation, using Bayesian optimisation, active learning or comparable methods, to reach the same tuning outcome in less device time
• Apply computer vision and signal analysis to device measurement data where those methods outperform simpler alternatives
• Build the feature and telemetry pipelines out of the calibration store that these models depend on
• Quantify uncertainty, so the orchestration can separate a high-confidence recommendation from a low-confidence one and act accordingly
• Validate models against held-out device data, including the case where the device has changed since training
• Deploy models into the calibration loop with monitoring, fallback paths and a kill switch
• Distinguish real drift and defects from measurement noise, and set the thresholds that trigger action
• Work with physicists to encode what they already know as priors and constraints rather than making the model learn it twice
• Instrument the loop so the effect of a model-driven calibration on qubit performance is measurable after the fact
• Feed device characterisation and noise models back to Compiler Services and Control & Error Correction
• Document models, assumptions and failure modes, so an automated decision can be explained to the owner of the affected device
