PsiQuantum'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 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.  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. Victor Peng, our CEO, and co-founder Jeremy O'Brien, now Executive Chairman, lead a team and board that reflects how seriously the world is taking this build, joined this year by Intel's Lip-Bu Tan and Atomico's Niklas Zennström.  PsiQuantum 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 Airbus, 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 now have the funding, the government validation, and the sites under construction to make it real.  Job Summary: The Technical Product Management Lead will serve as the technical face of the product to customers, partners, and the broader industry. This role will lead detailed specification negotiations and technical engagements with customer architecture teams, translating customer constraints and needs into clear, actionable product requirements. The Lead will partner closely with engineering on product priorities, trade-offs, testing, and documentation while owning specifications at the customer boundary. This individual will also develop technical content—including white papers, application notes, reference architectures, and conference materials—and represent the company at industry conferences and standards organizations. Responsibilities: • Lead technical engagement with customer architecture teams — design and architecture reviews.​ • Lead detailed specification negotiation with lead customers, from first draft through agreed sign-off.​ • Own spec definition at the customer boundary: how performance is measured, what a test proves.​ • Provide product management support to engineering — requirements, priorities and trade documentation.​ • Author white papers, application notes, reference architectures and conference material.​ • Feed customer-side constraints back into product definition as first-class requirements.​ • Represent the company technically at conferences and in standards work.​ Experience/Qualifications: • 10+ years in datacenter networking with real depth in switch and fabric architecture; product management or product-owner experience.​ • Has been the vendor architect in a room of skeptical buyers and won on merit.​ • Practical grasp of the optical layer as a networking engineer uses it: link budgets, transceiver compatibility, reach and loss margin.​ • Excellent written communication — a large share of the role is documents that survive scrutiny without you present.​ PsiQuantum provides equal employment opportunity for all applicants and employees.
