PCB Designer

PsiQuantum'smission is to build the first useful quantum computers-machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems.

Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.

Our architecture and approachisbased on silicon photonics. Byleveragingthe advanced semiconductor manufacturing industry-including partners like GlobalFoundries-we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photonsdon'tfeel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024,PsiQuantumannounced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining-and that now is the time to scale.

PsiQuantumalso develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies-including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical-to prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shift-and a path to mastering challenges that cannot besolvedany other way. The potential is enormous, and we have a clearpathto make it real.

Job Summary:

The Circuits team sits at the interface of hardware development, manufacturing, and the system architecture to design the first fault-tolerant quantum computer. We are looking for a circuit design engineer to join the team. This is an individual contributor role involving close collaboration with all PsiQuantum' s technical teams with a focus on PICs design (schematics and floor planning, performance prediction, etc.), screening and test plans, as well as developing software tools for optical and quantum simulations. PIC designs particularly relevant to this role are complex photonic switch networks.

Responsibilities:

• Work closely with photonics, electronics, and test engineers on data-driven circuit analysis.
• Design software functionality to meet requirements for parts of our in-house software design flow.
• Develop methodologies for evaluating implementation concepts and determining their feasibility.
• Extract predictive models, perform analysis, and run design checks on circuits.

Experience/Qualifications:

Essential:

• PhD or equivalent in EE, Physics, Computer Science or related field.
• Ability to work effectively in a new area designing first-of-their-kind photonic circuits.
• Experience programming in Python.
• Ability to work across domains and collaborate effectively with multi-disciplinary technical teams.

Preferred:

• Experience with high-speed electro-optic phase shifters.
• Familiarity with photonic circuit concepts and GDS layout.
• Familiarity with git workflows and CI/CD pipelines.
• Working knowledge of quantum computing/quantum mechanics.

Useful:

• Background in analogue and/or digital electrical circuit design.
• Professional experience programming and releasing production code for web applications, Javascript/Typescript, and modern front-end tools e.g. React, Svelte, and/or Vue.
