At OQC, we aren’t just theorising about the future; we’re building it. Born from a philosophy of bold innovation, we’ve transitioned quantum computing from an academic ambition into a commercial reality - and we’re just getting started.
The Purpose
As a Quantum Software Engineer in Calibration Operations, you’ll develop automated calibration and benchmarking solutions that are essential to keeping OQC’s quantum computers accurate, stable and available.
Quantum systems naturally drift and are highly sensitive to their environment, so effective calibration is a continuous operational requirement - not a one-off activity. Your work will directly enable reliable system performance for both production workloads and research.
The Role
This is a quantum-focused software role at the intersection of experimental physics, automation and production engineering. You’ll turn calibration knowledge into robust software and workflows used for system bring-up, daily operation, performance monitoring and research and development.
Working closely with measurement and calibration teams, you’ll understand device behaviour and translate scientific requirements into effective tooling. You’ll own quantum-software projects from requirements and experimental validation through to production deployment, collaborating with control-systems engineers, researchers and platform teams throughout delivery.
You’ll contribute through design reviews, pair programming and shared problem-solving, supporting the engineers and scientists who use your tooling. You’ll also share knowledge through documentation, technical presentations and contributions to the wider quantum community.

The ‘Nice-to-Haves’
Why Join OQC
You’ll tackle a continuous challenge at the heart of operating quantum computers: turning experimental knowledge into software that keeps systems accurate, stable and available, day after day.
This is an opportunity to own software projects from scientific requirements through to production, help shape the calibration roadmap and explore new approaches alongside engineers and researchers. Your work will support the people running experiments, the systems delivering production workloads and the calibration capabilities needed for future generations of quantum devices.

Develops superconducting quantum computers and services
Oxford Quantum Circuits (OQC) is a UK quantum computing company that builds superconducting quantum systems using its Coaxmon architecture and offers Quantum Computing as a Service through cloud access and colocated data centers. Its products work by using superconducting qubits implemented with the Coaxmon design, allowing users to run quantum programs remotely via a cloud interface or at partner data centers, with plans for larger TITAN systems aimed at fault-tolerant computing. What sets OQC apart from competitors is its specific Coaxmon architecture and its focus on scaling up infrastructure across international locations, backed by a large Series C funding round and strategic investors, to push toward practical, fault-tolerant quantum computing. The company’s goal is to expand its global infrastructure and develop next-generation TITAN quantum systems to achieve fault-tolerant quantum computing at scale.
