Integrated Optics Designer

About Oxford Ionics

Oxford Ionics is a start-up building Quantum Computers to revolutionise industries from drug discovery to material design. Quantum Computing offers a radically new way of building computers that harnesses the power of quantum physics to be exponentially more powerful than conventional supercomputers. We are using unique trapped-ion technology to build the first Quantum Computers that can realize this potential.

Located in Begbroke Science Park with great transport links to Oxford’s beautiful city centre and University as well as London, we are an agile, ambitious company who champion creative thinking in a fast-paced environment at the cutting edge of technology.

Our Technology

Our quantum computers are based on microfabricated ion trap chips. These chips, built using our custom multi-layer process, have patterned metal structures which serve to confine individual atomic ions tens of microns above the surface. Optical components can be integrated into the dielectrics that separate the metal layers. Typical integrated optical elements include high-contrast single-mode waveguides, power splitters, and grating couplers. These need to operate in the near-UV to near-IR wavelength range, (approx. 375 nm – 900 nm). Integrated optics serves to deliver laser light to individual ions across a large chip with high power efficiency and low crosstalk – see this animation from MIT Lincoln Laboratory for a hint of what this may look like.

Your Application

We are seeking an experienced, highly motivated engineer to lead our optical integration efforts. You will work closely with our quantum scientists to define the chip functionality and performance requirements. Your role will involve designing and validating the performance of on-chip optical elements. You will also collaborate with our fabrication team and external partners to optimise the power efficiency and crosstalk of the devices.

Essential Requirements

You must have hands-on experience in designing and characterising photonic integrated circuits. You must know how to simulate photonic devices using tools such as COMSOL, Lumerical or similar.

Role and Responsibilities

You have experience with silicon photonics

Have you designed and tested novel PICs or photonic devices in the telecom band? Perhaps you designed systems for high-speed optical communication or optical computing? If you’re excited to take your expertise to a new – and much less explored - wavelength regime, we would love to hear from you.

You have fabricated custom photonic components

As an integrated optics designer, you will not be fabricating the devices yourself. However, your fabrication experience will help you understand the main challenges involved in turning your designs into reality. Whether you made active opto-electronic components, passive sub-wavelength photonics, or anything related, your experience can help us build useful photonic chips faster, and we would love to hear from you.

You have a background in integrated quantum photonics

Have you designed and built photonic devices for quantum applications? Maybe this was in the context of quantum information processing, quantum key distribution or single-photon generation/manipulation/detection? If you’d like to apply your expertise in a regime where qubits only move when you want them to move, and where losing a single photon is really not a problem, we would like to hear from you.

You have a desire to learn and take on new challenges

You function well with unfamiliar challenges. You enjoy learning from colleagues who have a very different knowledge base to you, and enjoy sharing knowledge so that they may learn from you too. You are a strong communicator who is confident enough to ask questions and able to recognise when you could be doing something better. At the same time, you must be motivated to use your initiative and tackle big problems.

Benefits

We offer a competitive package including share options. Flexible and partial remote working will be considered.

How to Apply

Apply by email to careers@oxionics.com with:

 

  • Your CV

  • A brief cover letter explaining your background and interest in the role

Application closing date:  12th November 2021

If your application is successful, you will have an introductory chat with a member of our team so we can get to know you on your terms, tell you more about Oxford Ionics and the role and let you ask us any questions you have. We’ll ask you about your background, relevant experience and your interest in working with us.

We aim to let you know if we will move forward to the main interview within one week of our initial chat. All our interviews can be conducted over video calls if you are more comfortable with this, otherwise we would love to show you around the facilities at your main interview to give you a feel for what working with us would be like.

We want you to be comfortable and able to show yourself off in the best possible light. If there are any accommodations we can make during the interview process to make things easier for you, please let us know.

 

At any point, please feel free to email any questions to careers@oxionics.com

We look forward to meeting you!
