Software Engineer, Automated Calibration Services

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: knowing which 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

Laboratory instrument control: QCoDeS, Labber, pyvisa, SCPI, or an in-house equivalent

Qubit calibration, tune-up or device characterisation, on any qubit modality

Machine learning applied to device tuning: Bayesian optimisation, Gaussian processes, active learning, or computer vision on device data

Anomaly and drift detection on production telemetry

Control theory and closed-loop feedback

FPGA or HDL exposure, enough to work with the engineers who build the calibration engine

Realtime or embedded systems, where deadlines are real

Orchestration frameworks such as Airflow, Dagster, Prefect or Temporal

Quantum computing exposure of any kind (no physics degree required)

Publications, open source contributions, or a hardware automation project you are willing to talk through

SQC is an equal opportunity employer. We value diverse perspectives and experiences, and encourage applications from candidates who may not meet every listed requirement. If you’re excited about the role and believe you can contribute, we encourage you to apply.

This position may require access to export-controlled information or technology. Employment may be subject to applicable export control laws and may require eligibility assessment based on factors such as nationality, citizenship, or residency, and, where necessary, obtaining relevant export licenses or approvals.

SQC was founded by renowned physicist and materials scientist Michelle Simmons, who pioneered the field of atomic electronics, including the development of the world’s first single-atom transistor and the first integrated circuit built with atomic precision. Our Chair, Simon Segars, former CEO of Arm, is a leader in the semiconductor industry and was instrumental in developing the processors that powered the mobile computing revolution.

As a full-stack company with in-house QPU manufacturing, SQC can design, produce and test new quantum chips in under a week, enabling rapid iteration and a decisive advantage in the race to build the world’s first commercial-scale quantum computer.

SQC is a high-accountability environment built on a simple principle: Every Atom Counts. If you’re looking to play a meaningful role in building the next frontier of computing, we’d love to hear from you.
