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.
In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining—and that now is the time to scale.
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 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 have a clear path to make it real.

Job Summary:
The Quantum Architecture team at PsiQuantum is responsible for the high-level design of our photonic fusion-based quantum computer. We understand that success requires not only breakthrough ideas, but the discipline to rigorously test, validate, and refine them.
We are hiring an engineering manager to validate fault-tolerance techniques using multi-scale simulations of a photonic quantum computer. This role lies at the interface of theory and engineering, and suits a detail-oriented candidate able to rapidly move ideas past the proof-of-concept phases of R&D to prototyping and implementation. You will work with software engineers and world-leading experts in quantum error correction and linear optics, clarifying requirements for the integration of new methods and general development of our simulation framework. You'll have a talent for project management, keeping things on track and aligned with our technical roadmap.
Responsibilities:
- Coordinate and mentor a team of dedicated software engineers and quantum architects.
- Assimilate complex theoretical ideas and translate them into concrete engineering and simulation requirements.
- Collaborate with senior quantum architects to scope our simulation roadmap and coordinate the delivery of its milestones.
- Extend and improve simulation capabilities.
- Work closely with software teams to develop and promote shared tools and infrastructure for accelerating development and integration.
Qualifications & Experience:
- 7+ years of software development experience and familiarity with best practices towards design, workflows, and testing. Experience with simulation of large-scale systems a bonus.
- Degree in Physics, Computer Science, Engineering or related technical / scientific field.
- Experience with technical roadmaps, cross-team dependencies, and iterative R&D cycles.
- Proven team player with an ability to work effectively across departments, sites, and time zones.
- While a background in quantum error correction is ideal, candidates with experience at any interface between engineering and physics are strongly encouraged to apply.
