Photonic Layout Engineer in Oxford

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.

We are looking for a Photonic Layout Engineer to join our QPU Design team at Oxford Ionics/IonQ. In this role, you will be responsible for the layout of photonic integrated circuits (PICs) that form a central part of our Quantum Processor Units (QPUs). You will work closely with scientists, photonic design engineers and fabrication engineers to bring new designs for ion trapping chips into production.

You’ll 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:

• Integrating photonic components into complex multi-layer chips.
• Arranging and routing photonic components on chip, in coordination with metal track and CMOS routing.
• Producing reticle-size photonic layout files using Python scripts as part of tape-out of the full chip, suitable for use in a commercial foundry.
• Collaborating with scientists to discuss their requirements.
• Interfacing with photonic designers, test engineers, packaging engineers and fabrication engineers to define design rules and shape component design.
• Layout verification through DRC and LVS.
• Contributing to custom layout Process Design Kits (PDKs) that are specific to IonQ and the foundry.
• Documenting the layout process and the final tape-out mask files.

Requirements

To be successful in this role you will need significant experience in the design and layout of Photonic Integrated Circuits (PICs). We are looking for someone who can consider requirements and constraints from other parts of the chip in the layout process, understand the purposes of different photonic components, enjoys complex layout work and can contribute effectively within a fast moving, highly technical team.

You'd be a great fit with:

• Proficiency in Photonic Integrated Circuit layouts.
• Familiarity with the principles of photonic devices, such as waveguides, beamsplitters, grating couplers or similar, including design, test and fabrication.
• At least 2 years of experience working with Python software packages, specifically for photonic mask layout, such as Luceda IPKISS, GDSFactory or Klayout.
• A degree in Photonics, Physics, Electrical Engineering or a related field, or equivalent industry experience.
• Strong collaboration and communication skills, and the ability to work independently and prioritise tasks in a time-sensitive environment.
• Experience in generating layout files for photonic devices or complex semiconductor devices, particularly with custom elements.
• Knowledge of the manufacturing processes and techniques in these two fields would also be helpful.
• A background in commercial simulation, verification and layout environments such as Synopsys, Cadence or Ansys is desirable.
• Strong programming and software skills would also be an asset in this role.

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.
