Description du poste

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 architectureand approachisbased on silicon photonics. Byleveragingthe 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: photonsdon'tfeel 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,PsiQuantumclosed a$1 billionfunding 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'smost 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 ExecutiveChairman, 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 NiklasZennstrom.

PsiQuantumalso 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, includingAirbus,LockheedMartin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical, to prepare quantum solutions for real-world impact.

Quantum computing is not an extension of classical computing. Itrepresentsa fundamental shift, and a path to mastering challenges that cannot besolvedany other way. The potential is enormous, and we now havethe funding,the governmentvalidation, andthe sitesunder construction to make it real.

Job Summary:

Quantum computing has the potential to solve important problems beyond the reach of conventional computers. At PsiQuantum, we're building a general-purpose silicon photonic quantum computer to tackle these challenges.

We're seeking a Photonic Model Integrator to develop and maintain our library of photonic component and circuit models. This role sits at the intersection of photonic circuit design, CAD infrastructure, and electromagnetic (EM) modeling. You'll help ensure that schematic, layout, and extracted models stay consistent, automated, and ready for simulation.

Responsibilities:

• Develop physics-based models of photonic components for quantum circuit simulations.
• Build and maintain a library of photonic component models.
• Develop component- and circuit-simulation tools and pipelines.
• Improve the reproducibility of design-to-simulation workflows.
• Collaborate with PDK engineers to maintain model links to process design kits.

Experience/Qualifications:

• MS or PhD in Electrical Engineering, Applied Physics, or a related field.
• 6+ years of experience in integrated photonics.
• Strong Python scripting skills.
• Experience with photonic layout tools such as KLayout or Cadence Virtuoso; EM solvers such as Lumerical FDTD/MODE, HFSS, CST, or Tidy3D; and circuit simulators such as SPICE, INTERCONNECT, Caphe, or PhotonForge.
• Excellent verbal and written communication skills, with the ability to communicate effectively with varied audiences.
• Strong critical thinking, analytical, and problem-solving skills; creativity, initiative, and attention to detail.
• A track record of delivering impactful results.
• Ability to work independently with limited direction, manage multiple priorities, and deliver on schedule.
• Demonstrated interest in quantum computing.
• Ability to contribute in a fast-paced startup environment.
