About The Position

PsiQuantum's mission is to build the first useful quantum computers capable of delivering breakthroughs in various foundational industries. Founded in 2016, the company focuses on building and deploying million-qubit, fault-tolerant quantum systems. Their architecture leverages silicon photonics and advanced semiconductor manufacturing, including partners like GlobalFoundries, offering natural advantages for scale such as immunity to heat and electromagnetic interference, and integration with existing cryogenic cooling and standard fiber-optic infrastructure. In 2024, PsiQuantum announced government-funded projects to support the build-out of utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. PsiQuantum also develops algorithms and software, working with leading Fortune 500 companies to prepare quantum solutions for real-world impact. The Technical Lead for Single Photon Source Validation will be responsible for successfully driving validation projects, including the planning, design of experiments, and characterization of electro-optical assemblies based on single photon source generation optical circuits and superconductive single photon detectors.

Requirements
