At OQC, we aren't just theorising about the future; we're building it. Born from a philosophy of bold innovation, we've successfully transitioned quantum computing from an academic dream into a commercial reality. The most exciting thing is that we're just getting started and we've recently closed our £260 million Series C funding round - the largest fundraise ever completed by a quantum computing company in Europe.
The Purpose
Your mission is to advance the performance and reliability of quantum systems by building software that enables efficient calibration and benchmarking. You'll help turn complex quantum workflows into scalable, production-quality tools that keep our quantum computers running at their best.
The Role
You'll work at the intersection of quantum physics, software engineering, and data-driven optimisation. As part of our calibration teams, you'll build core components of OQC's quantum calibration stack, collaborating closely with engineers and researchers to design, develop, and deploy software that supports system bring-up, daily calibration, and ongoing performance improvement.
What You'll Be Working On
- Own quantum software projects end to end, from requirements through to deployment
- Design and build components for system bring-up, daily calibration, and benchmarking workflows
- Use data to create novel procedures and inform calibration workflow decisions
- Debug and resolve issues across development and production environments
- Collaborate through pair programming, code reviews, and shared technical problem-solving
- Build scalable software solutions that help engineers conduct research and operate quantum systems reliably
- Contribute to research, innovation, and knowledge sharing across OQC and the wider quantum community
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
