Job description

Overview

Quantinuum are hiring a research software engineer to work on compilation of fault-tolerant quantum software for the next generation of quantum computers.

Quantum software relies on quantum error correction to work. However, quantum software engineers don’t want to think about error correction: they want the compiler do it for them. So we’re upgrading our TKET compiler do this, and we’re looking for help.

Responsibilities

• As part of our Cambridge-based compiler team, you will contribute to our quantum compilation toolchain, with a focus on how implementing fault-tolerant protocols in the compiler.
• You’ll stay informed about the latest research on quantum error correction codes, fault-tolerant circuit design, and quantum compilation methods, as well as conducting original research of your own.
• You’ll work with scientists and engineers from all across Quantinuum to integrate all of our expertise into high-quality software for our team, and our customers.

Qualifications

• Hold a PhD in Mathematics, Physics, or Computer Science.
• Have experience programming in Python, Rust, or C++, and be willing to learn new programming languages.
• Be comfortable with graduate-level mathematics.
• Knowledge of quantum computing, especially quantum error correction.
• Be an independent worker capable of understanding technical and advanced research material and transferring new ideas into code.
• Be able to present and discuss new research ideas in a collaborative environment.

Nice to have

• Experience of modern compilers and intermediate representations, such LLVM or MLIR.
• Experience of software development in a team environment, using version control, issue trackers, and similar tool
• Extensive experience of QEC and software engineering

What is in it for you?

Working alongside a highly talented team, with leading names in the quantum computing industry. We offer a highly competitive package, equity, 28 days of paid holiday (in addition to public holidays), a workplace pension, a positive approach to flexible working and enhanced parental and adoption benefits.
