Job summary

Silicon Quantum Computing (SQC) in Sydney is seeking a Software Engineer for Automated Calibration Services. You will build software to monitor, automate and drive calibration protocols that keep qubits within spec during runs, collaborating closely with physicists and engineers at our Sydney facility.

The role owns the execution path at room temperature, on accelerators and at the logical qubit layer, including the dependency graph, realtime service and FPGA engine.

Qualifications

• 4+ years building production software, ideally where the software drives physical hardware.
• Strong Python, including the scientific stack (NumPy, SciPy, pandas), plus a systems language such as Rust or C++.
• Workflow orchestration and dependency graphs: DAG scheduling, ordering, failure handling and partial re-runs.
• Numerical work in practice: curve fitting, parameter estimation, optimisation, and knowing when a fit is not to be believed.
• Time series and signal data, including the basics of filtering and characterising noise.
• Working with instruments or devices that are stateful, slow, and sometimes unavailable.
• Data provenance and reproducibility: inputs, versions and device state produced a result.
• Observability, and measuring a system that runs unattended.
• Reading a protocol written by a scientist and turning it into code, then talking it back through with them.
• Git workflow, code review, CI, and testing code that depends on hardware.
• Clear technical writing.

Responsibilities

• Build the orchestration that runs calibration protocols (dependency graph, ordering, scheduling, retries).
• Implement the protocols handed by physicists as automated, monitored software routines.
• Build and run the realtime calibration service and drive the FPGA calibration engine.
• Own the calibration store: results, provenance, versioning, and queries.
• Develop drift characterisation and qubit health analytics to decide reruns.
• Support triggers: scheduled, compiler-requested, and monitoring-driven.
• Collaborate with Control & Error Correction to fit calibration into duty cycles.
• Publish device state, noise models and duty cycles Compiler Services uses.
• Instrument the path so calibration runs are reproducible and explainable.
• Analyze device data to separate drift from noise and assess improvements.
• Translate physicists' protocols into code and review with them.
• Document implemented protocols, dependency model and procedures.
