QPU Design 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 QPU Design Engineer to join our Processor Design team at Oxford Ionics/IonQ. In this role, you will be responsible for integrating all the features required for the successful operation of our quantum computers into complex chips. You will be directly contributing to the team’s mission of advancing the design of high-performance quantum processing units, the novel technology that sits at the very heart of our quantum computers. You will work closely with scientists and fabrication engineers, understanding how the various parts of a chip influence and constrain each other, to bring new designs for ion trapping chips into production.

You will play an important part in shaping the hardware that supports our work in building the world’s most advanced quantum systems.

What you'll be responsible for:

In this position, your primary responsibility will focus on turning operational requirements into chip layout, supporting the effective delivery of devices that enable the use of new technologies. You will have the opportunity to expand the range of features supported by our chips, contributing directly to the success of building utility-scale quantum computers.

Key responsibilities include:

• Guiding the end to end chip design process, from requirements to layout and tape-out.
• Coordinating with other teams to ensure feasibility and compatibility between the various layers of the chip.
• Collaborating with scientists to discuss their requirements and settle on specifications.
• Laying out complex multi-layer chips, including metal track routing and interfaces with photonics and CMOS.

Requirements:
To be successful in this role, you will need prior hands-on experience in chip layout, specifically translating design requirements into feature, as well as taking on layout work. We are looking for someone who can work cross-functionally to define various aspects of chip design, contributing effectively within a fast moving, highly technical team. You will need to be able to take charge of projects independently, solve problems along the way and drive the design process while taking responsibility for delivery of the final tape-out.

You'd be a great fit with:

• At least 3 years of industry experience leading complex chip design and in IC layout.
• A degree in engineering, electronics or science, or equivalent industry experience in a technical or scientific environment.
• Proven ability to consult and coordinate between multiple stakeholders.
• Strong collaboration and communication skills.

Additional experience that may be beneficial includes experience in scripted generation of layout (GSDFactory in Python or similar), using Cadence for IC layout, and experience in ion trap and/or photonics design or IC packaging.

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.
