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.
What To Expect:
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.
Reasons to use Rodeo
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You'll Be Responsible For:
- Developing our quantum compiler
- Writing embedded firmware
- Designing high-level APIs as part of our quantum computing stack
- 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 (
- 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.
Requirements
This role is suitable for an individual with over 5 years of professional software development experience, working with both scripting and systems programming languages. We expect knowledge in one or more mainstream programming languages and an interest in working with Python and Rust, though prior experience is not a prerequisite. You will be used to maintaining high code quality, through code reviews and appropriate testing, and maximising impact through quick iteration and short cycles of learning and improving the code.
Get help with your application
Your very own career expert that helps elevate your application to the next level.
We also expect that you are experienced leading projects and initiatives, and are comfortable with adjusting requirements as we explore solutions. You should have excellent communication skills not just within software engineering but across disciplines. This role is well suited to someone who enjoys complex technical problems. We do not expect prior experience of quantum computing.
Benefits
Be part of a team that’s shaping the future of quantum. We offer more than just a role, you’ll join a world class community of scientists, engineers and innovators working to unlock the full potential of quantum computing.
We offer a range of benefits, including opportunities to further your career alongside industry leaders, a competitive salary with IonQ stock options, an annual performance bonus, generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family, and much more.
Join us and be part of the future of quantum computing.
We’re proud to be an equal opportunity employer and welcome applicants from all backgrounds.
