Senior Software Engineer

Quantum Computing Engineer Opportunity

Quantum is now, and it's built here.

Oxford Ionics, now part of IonQ, is pioneering the next generation of quantum computing. Using our world-leading trapped-ion technology, we're building the most powerful, accurate and reliable quantum systems to tackle problems that today's supercomputers cannot solve.

Joining Oxford Ionics means becoming part of a global IonQ team that is transforming the future of quantum technology - faster, at scale, and with real world impact.

We're looking for a skilled, motivated Senior Software Engineer with a high level of initiative who will thrive in our growing team of expert engineers and scientists.

Oxford Ionics is on a mission to develop useful quantum computers that can be delivered at scale and are in demand for solving real-world problems. Our research and development efforts build on our fully integrated quantum processors that can be fabricated within standard silicon foundries. We have achieved the lowest error rates for single-qubit and two-qubit operations in the industry.

This is an exciting opportunity for a Senior Software Engineer who enjoys working with other software engineers as well as scientists.

The opportunity offers a wide variety of exciting work, from developing our quantum compiler to writing embedded firmware, from designing high-level APIs as part of our quantum computing stack to advancing our internal development infrastructure and process.

Our technology stack:

• Python and Rust
• Much of our software is used by our scientists when executing routines on our quantum hardware. The APIs used by the scientists are all Python-based.
• We are developing a custom-optimising compiler for quantum circuits written in Rust and Python.
• The firmware components of the instrumentation and control system we use, ARTIQ, are written in Rust. We will be customising and extending this firmware to improve performance and add new features.
• FPGAs and SoCs
• We'll develop custom hardware and gateware to extend our hard real-time (<1 ns) distributed control system.
• Qubits
• The quantum core of our hardware is built from trapped-ion qubits, controlled by chips designed and assembled in-house by our microfabrication team.
• You will have some flexibility over your tools, like which editor you want to use or which operating system. We use Git for our version control.
