Senior Quantum Applications Architect

About the role

<p><span data-contrast="auto">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.</span><span data-ccp-props="{"201341983":0,"335559739":200,"335559740":276}">&nbsp;</span></p> <p><span data-contrast="auto">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.</span><span data-ccp-props="{"201341983":0,"335559739":200,"335559740":276}">&nbsp;</span></p> <p><span data-contrast="auto">Our architecture&nbsp;and approach&nbsp;is&nbsp;based on silicon photonics. By&nbsp;leveraging&nbsp;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&nbsp;don't&nbsp;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}">&nbsp;</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,&nbsp;PsiQuantum&nbsp;closed a&nbsp;$1 billion&nbsp;funding round that valued the company at&nbsp;$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,&nbsp;PsiQuantum's&nbsp;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&nbsp;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&nbsp;Zennström.</span><span data-ccp-props="{"201341983":0,"335559739":200,"335559740":276}">&nbsp;</span></p> <p><span data-contrast="auto">PsiQuantum&nbsp;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&nbsp;Airbus,&nbsp;Lockheed&nbsp;Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical, to prepare quantum solutions for real-world impact.</span><span data-ccp-props="{"201341983":0,"335559739":200,"335559740":276}">&nbsp;</span></p> <p><span data-contrast="auto">Quantum computing is not an extension of classical computing. It&nbsp;represents&nbsp;a fundamental shift, and a path to mastering challenges that cannot be&nbsp;solved&nbsp;any other way. The potential is enormous, and we now have&nbsp;the funding,&nbsp;the government&nbsp;validation, and&nbsp;the sites&nbsp;under construction to make it real.</span><span data-ccp-props="{"201341983":0,"335559739":200,"335559740":276}">&nbsp;</span></p> <p><strong>Job Summary:</strong></p> <p data-renderer-start-pos="1">Within the Quantum Algorithms team, we develop and adapt quantum algorithms, identify and scope promising use cases, and analyze their resource requirements. In this role, you will translate computational tasks into abstract quantum-algorithm specifications, analyze their asymptotic performance, and define meaningful problem instances that lie beyond the practical reach of classical computation. You will also work closely with PsiQuantum’s Compilation team to devel
