By leveraging the 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: photons don't feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.</span><span data-ccp-props="{"201341983":0,"335559739":200,"335559740":276}"> </span></p> <p><span data-contrast="auto">That approach has since been tested at the highest level of scrutiny the U.S. government applies to emerging technology, and it has held up. In 2025, PsiQuantum closed a $1 billion funding round that valued the company at $7 billion. In 2026, the U.S. Department of Commerce signed a $100 million Letter of Intent under the CHIPS and Science Act, followed by a $125 million agreement with DARPA under Stage C of its Quantum Benchmarking Initiative, PsiQuantum's most valuable U.S. government agreement to date. This year, we also broke ground on our utility-scale quantum computer in Brisbane, Australia, and continued building out our Chicago site.

These subsystems each perform a specific function of the quantum computer to generate entangled states of photons that, when scaled up and networked together, collectively enable quantum error correction and quantum algorithms. The successful candidate will lead a focused team to validate the performance of one or more fully integrated quantum subsystems, including photonic, optic, cryogenic, electronic, electro-optical, firmware, and software aspects. The team will plan and execute design validation testing of the subsystem, define and validate automated self-test functions, and develop novel quantum characterization, verification, and validation techniques for photonic qubit states. </p> <p><strong>Responsibilities:</strong></p> <ul> <li data-renderer-start-pos="3">Manage the validation team of the quantum subsystem, including technical oversight, project management, talent management, performance evaluations, and coaching.</li> <li data-renderer-start-pos="3">Develop validation and verification plans, and execute to deliver on these objectives within a demanding development schedule.</li> <li data-renderer-start-pos="3">Plan and execute system integration test points of hardware, firmware, software, to ensure that issues are identified and debugged at an appropriate level of integration before the full subsystem test.</li> <li data-renderer-start-pos="3">Lead the definition and documentation of the quantum and semi-classical calibration, self-test, and diagnostic functions of the subsystem. Define and validate quantum tests at intermediate points in the quantum computer, to verify the quantum photonic states being generated meet system requirements.</li> <li data-renderer-start-pos="3">Provide cross-functional support to other engineering teams by communicating design-for-test requirements, calibration requirements, data acquisition and processing requirements, performance data, and debugging support for all issues arising during subsystem-level tests.</li> <li da
