Quantum Software Engineer

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.

As a Quantum Software Engineer in our compiler team, your mission is to advance the performance of quantum systems by developing software that enables efficient compilation, execution, and optimisation of quantum programs. You’ll play a key role in tackling some of the hardest challenges in the field—including quantum error mitigation and quantum error correction—to bring reliable quantum computing closer to reality.

The Role

You’ll work at the intersection of quantum physics and software engineering, building core components of our quantum toolchain. Collaborating closely with internal teams and external stakeholders, you’ll design, develop, and deploy scalable software solutions that directly impact how quantum computers are programmed and operated.

What You'll Be Working On

• Owning end-to-end development of quantum software projects—from requirements through to deployment
• Designing and building components of the quantum toolchain (e.g. qubit routing, placement, circuit optimisation, pulse scheduling)
• Collaborating on solutions for quantum error mitigation and quantum error correction, improving system reliability and performance
• Translating high-level quantum programs into instructions optimised for execution on quantum hardware
• Debugging and resolving issues across development and production environments
• Collaborating with engineers through pair programming, code reviews, and shared problem solving
• Contributing to research, innovation, and knowledge sharing across the team and wider quantum community

What We're Looking For

• Strong programming experience in Python and familiarity with modern software engineering practices
• Solid understanding of computer science fundamentals (algorithms, data structures, systems design)
• Experience designing and delivering complex software systems from concept to production
• Knowledge of quantum computing principles, with particular emphasis on quantum error correction / error mitigation techniques and quantum circuits compilation principles
• Ability to debug complex systems and take ownership of production-quality code
• Strong communication skills and ability to collaborate across technical and non-technical stakeholders
• Degree-level knowledge in computer science or a related numerical discipline

The 'Nice-to-Haves'

• Hands-on experience working with quantum computers or quantum software stacks
• Experience developing algorithms for quantum systems, particularly in error correction or noise-aware optimisation
• Background in quantum theory or superconducting circuits
• Experience with distributed systems, message brokers, or data streaming tools
• Contributions to research, publications, or conference presentations in quantum technologies
• Postgraduate qualification (MSc or PhD) in a relevant field

Why Join OQC

You will join a world-class team at the forefront of the next computational era. We offer a culture of bold innovation, the chance to work with unique lab infrastructure, and the opportunity to see your work redefine the limits of computation.
