Principal Power Systems Architect, Quantum Infrastructure

Psi Quantum's mission 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 approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry-including partners like Global Foundries-we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don't feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.

In 2024, Psi Quantum announced 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.

Psi Quantum also 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. It represents a fundamental shift-and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.

Job Summary:

Power Systems Architect, Quantum Infrastructure will serve as the critical interface between the hardware architecture team, the facility engineering team, and the internal electronics design team. This role will define how utility power is brought into the building, conditioned, distributed, isolated, and grounded to support a large-scale quantum computing system with exceptionally demanding requirements for power integrity, harmonic control, conducted and radiated EMI mitigation, noise suppression, and system reliability.

This person will help shape the electrical foundation of a next-generation quantum computing facility, ensuring that large building-scale power systems and sensitive electronics are designed as one coherent architecture. This is a highly cross-functional role for someone who is equally comfortable discussing electrical noise, harmonic distortion, grounding, shielding, transformers, UPS modes, filters, conducted EMI, radiated EMI, and power quality with facilities teams, while also guiding electronics and hardware teams on grounding, AC-DC power conversion, and noise mitigation strategies at the equipment level.

Responsibilities:

* Serve as the primary technical interface between the hardware architecture team and facility engineering for all matters related to building power, conditioning, distribution, grounding, isolation, shielding, EMI, and power quality.

* Develop and own top-level specifications for facility electrical power systems supporting quantum computing hardware, including utility power characteristics, distribution architecture, fault tolerance, redundancy, and maintainability requirements.

* Define power quality requirements for sensitive hardware and translate those requirements into actionable specifications for facility and equipment design.

* Analyze and mitigate the impact of electrical noise, harmonic distortion, voltage transients, conducted EMI, radiated EMI, common-mode disturbances, and other interference mechanisms on sensitive systems.

* Analyze and mitigate coupling paths between building-scale aggressor loads and noise-sensitive circuits and subsystems.

* Define grounding, bonding, shielding, and cable management strategies…
