Front End Engineer

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 are looking for a Front End Engineer who excels at crafting intuitive interfaces that help engineers and scientists interact with complex technical data. You’ll lead the design and implementation of systems that translate experimental results and engineering workflows into clear, insightful visual experiences.

Working alongside the team developing the core quantum systems software, you will create front-end tooling to enable our Scientists to do fast development and experimentation. You will also develop interactive tools to help our systems team build and test quantum hardware.

This is an exciting opportunity to work alongside scientists, engineers, and technicians. See vacuum chambers, cryostats, lasers, and more in action at our on-site laboratories and play your part in making quantum computing happen.

What you'll be responsible for:

As our first dedicated Front End hire, you will be primarily responsible for designing and developing front-end applications that visualise scientific and engineering data in real time, in order to assist our Science team with their experimentation. You will collaborate with domain experts to turn raw models, simulations or measurements into accessible and informative user interfaces. These interfaces will be responsive and performant using modern frameworks (e.g. Svelte, SolidJS, React etc.). You will also work closely with run time engineers to integrate APIs and data processing pipelines.

More broadly, you will contribute to UI/UX design strategy with a focus on clarity, interactivity, and accuracy of technical content. Through testing, peer reviews, and continuous integration, you will maintain high quality code. This role will have ownership of document design decisions and collaborate cross-functionally to ensure everything meets requirements and requisite improvements are made.

Requirements:
This role will require strong proficiency in JavaScript, TypeScript, HTML and CSS as well as experience with data visualisation libraries (e.g. D3.js, Plotly, ECharts) or custom rendering (Canvas/WebBL). We also expect familiarity with version control (Git), modern build tools, and component based UI systems.

Given the close relationship of this role with our Scientists and technical teams, a good understanding of scientific workflows or engineering processes is necessary, as well as comfort engaging with technical content. Additionally, this role will require excellent communication skills, with the ability to present complex information clearly and confidently to technical stakeholders.

Additional experience that would be helpful includes experience with Python or Rust backends, especially for scientific computing, and/or knowledge of Jupyter, WebAssembly, or scientific data formats (HDF5, NetCDF, FITS). A background in data dashboards, simulation visualisation, or instrument control interfaces would also be beneficial.

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.
