Senior Software Engineer (Quantum Compilers) in Reading

Quantum computing isn’t just the next step in technology - it’s a complete reimagining of what computing can be. At OQC, our compiler team sits at the heart of this transformation, creating the bridge between customer ideas and quantum hardware execution. We’re unlocking the true power of quantum technology, one breakthrough at a time. As our team expands, we’re seeking a Senior Software Engineer to help shape the future of our compiler stack - someone ready to combine technical vision with hands-on innovation, and to mentor others as we build the systems that will define the next era of computing.

You’re an experienced developer - ideally fluent in Python - with a strong foundation in library development, code optimisation, and deep engineering. You understand how software interacts with hardware at a fundamental level, and you’re driven by the challenge of building technology that redefines what’s possible. You’ll have the opportunity to go beyond your current specialisms - exploring new domains, tackling unique engineering challenges, and contributing to the systems that are pushing the frontiers of quantum computing.

In this role you will work closely with multiple teams, not only the compiler team, but also Cloud, DevOps and Quantum Theory teams to develop a deep understanding of the requirements from all layers of our stack. You’ll be responsible for:

• Setting priority of software development projects within the Compiler team, demonstrating your awareness of high level team goals and resourcing
• Developing and maintaining code within the OQC compiler to ensure it is fit-for-use and ready for deployment
• Gathering requirements from internal teams across the stack to create solutions that fit the needs of stakeholders.
• Designing approaches to new problems, taking decisions that consider strengths and drawbacks for a range of solutions
• Leading projects and assigning development tasks to Software Engineers to move team goals forward - Using your previous skill and experience to guide the team when challenges arise
• Mentoring other developers and reviewing their work, ensuring feedback supports the professional growth across the team
• Championing best practice both in the team and in the wider organisation; continuously reviewing industry trends and making recommendations in areas such as security and quality assurance

But this role isn’t just about the tech. You will be able to draw on your extensive knowledge of python coding and experience using scientific libraries. An appreciation for the interactions between software and hardware and knowledge of computer science principles gained either through a relevant degree or your natural sense of curiosity and desire to learn. Experience with classical compilers is a plus, but not essential — after all, quantum compilers aren’t classical. If you’ve worked with LLVM, TKET, or MLIR, we’d love to hear from you.

To truly thrive here, you’ll bring strategic thinking, technical leadership, and a passion for mentorship. You’ll help shape projects in an agile environment, guiding and uplifting less-experienced developers as we build the future of computing. If you’re ready to apply your expertise to the next level and grow with us in an environment that values curiosity, collaboration, and impact - we’d love to have you join us on this quantum journey.
