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 Senior Software Engineer in Calibration Operations, you'll design and build the software systems that automate calibration, benchmarking and bring-up of OQC's quantum computers.

Your work will support automated system bring-up, daily calibration and performance remediation, delivering reliable software for both production systems and rapidly evolving research environments.

The Role

You'll focus on system architecture, distributed workflows, event-driven services, observability and production reliability. You'll build the services and engineering capabilities that make calibration workflows scalable, resilient and easier to operate, diagnose and support.

Quantum computing knowledge is helpful, but not required. You'll work closely with quantum engineers and research scientists who provide the domain expertise,



alongside software engineers and platform teams.

You'll own software projects from requirements and architectural design through deployment and ongoing operation. Alongside hands-on development, you'll contribute to architectural decisions, establish engineering patterns and share software-engineering knowledge across the team.

What You'll Be Working On

• Design the architecture of scalable calibration and benchmarking services, building reliable software for automated system bring-up, daily calibration and performance remediation
• Develop event-driven systems to orchestrate calibration workflows and communicate their status and results, defining event schemas, service interfaces and data flows across distributed systems
• Build observability into calibration platforms through structured logging, metrics, distributed tracing, dashboards and alerting
• Improve the reliability, fault tolerance and recove
