It Software Engineer jobs in United Kingdom

At OQC, our quantum software stack is the bridge between high-level algorithms and the powerful quantum hardware that drives our mission. We’re looking for a Quantum Software Engineer to help solve the challenges of quantum code compilation, execution, and error correction — contributing directly to the performance and scalability of our quantum computing systems.

You’re a talented software engineer with a solid understanding of computer science fundamentals and a curiosity for the quantum world. Whether you’ve worked with quantum computers before or are eager to deepen your expertise, you’ll be joining a team where scientific exploration meets software excellence. You’ll design and develop the algorithms that underpin OQC’s quantum toolchain, turning complex theoretical ideas into production-ready solutions.

As a Quantum Software Engineer, your responsibilities will include:

• Designing and developing algorithms for qubit routing, qubit placement, noise-aware optimisation, pulse scheduling, and circuit optimisation.
• Translating high-level quantum instructions into low-level code that runs efficiently on OQC’s quantum hardware.
• Gathering requirements, proposing solutions, and managing the full software lifecycle — from prototype to production deployment.
• Debugging complex issues in development and production environments and ensuring robust, reliable solutions.
• Conducting code reviews and ensuring high standards of code quality, testing, and documentation.
• Collaborating across teams to understand stakeholder needs and build software that advances OQC’s technical capabilities.
• Sharing knowledge through mentoring, internal talks, and technical documentation.
• Representing OQC in conferences, research collaborations, and publications — contributing to the wider quantum software community.

You’ll bring solid experience in Python, strong knowledge of data structures, algorithms, and software design, and an understanding of quantum theory. You’ll be confident designing complex systems and working in a multidisciplinary environment where physics and software intersect. We're looking for engineers who are hands-on problem solvers, strong communicators, and committed to delivering quality in everything they build.

You may have experience in Quantum or scientific computing; Functional programming and system design; Front-end or web technologies such as Error mitigation and quantum circuit optimisation. And of course, you’ll bring a genuine interest in the quantum revolution and the drive to shape the future of computing.

If you think you’ve got what it takes to develop the algorithms and tools that power OQC’s quantum computers - and to help redefine the limits of what’s computationally possible - then we’d love to hear from you.
