Quantum computing holds the promise of humanity’s mastery over the natural world, but only if we can build a real quantum computer. PsiQuantum is on a mission to build the first real, useful quantum computers, capable of delivering the world-changing applications that the technology has long promised. We know that means we will need to build a system with roughly 1 million qubits that supports fault tolerant error correction within a scalable architecture, and a data center footprint.
By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over today’s most powerful supercomputers, offering the potential for extraordinary advances across a broad range of industries including climate, energy, healthcare, pharmaceuticals, finance, agriculture, transportation, materials design, and many more.
PsiQuantum has determined the fastest path to delivering a useful quantum computer, years earlier than the rest of the industry. Our architecture is based on silicon photonics which gives us the ability to produce our components at Tier-1 semiconductor fabs such as GlobalFoundries where we leverage high-volume semiconductor manufacturing processes, the same processes that are already producing billions of chips for telecom and consumer electronics applications. We also benefit from the quantum mechanics reality that photons don’t feel heat or electromagnetic interference, allowing us to take advantage of existing cryogenic cooling systems and industry standard fiber connectivity.
In 2024, PsiQuantum announced two government-funded projects to support the build-out of our first Quantum Data Centers and utility-scale quantum computers in Brisbane, Australia and Chicago, Illinois. Both projects are backed by nations that understand quantum computing’s potential impact and the need to scale this technology to unlock that potential. And we won’t just be building the hardware, but also the fault tolerant quantum applications that will provide industry-transforming results.
Quantum computing is not just an evolution of the decades-old advancement in compute power. It provides the key to mastering our future, not merely discovering it. The potential is enormous, and we have the plan to make it real. Come join us.
There’s much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!
Job Summary:
Our system architecture team sits at the interface of hardware development, manufacturing, and the quantum architecture to design the first fault-tolerant quantum computer. We are looking for a computational physicist to drive the efforts of developing internal tools for developing tools for designing and analyzing the system architecture in close collaboration with other technical teams.
Responsibilities:
Design and develop software tools and infrastructure to enable development, analysis and tracking of our quantum system architecture.
Contribute to our Quantum Computing system architecture and software system roadmap.
Develop and improve simulation tools that evaluate system models of photonic modules using Fock and Gaussian states.
Contribute to tool development for analysis and inspection of hierarchical multi-scale models of planned systems.
Maintain graph-based models modules and subsystems and infrastructure to ensure consistency and compatibility with up- and downstream models.
Experience/Qualifications:
Degree in Physics and a strong background in quantum optics and quantum information.
Proficiency in Python.
3+ years of experience in software development, with an emphasis on scientific computing.
Ability to collaborate effectively across departments, sites, and time zones.
A hands-on mentality to own challenges and develop solutions independently.
Competent use of collaborative software development tools (e.g., GitLab) is desirable.
Experience with Docker and Postgres is optional, but beneficial.

What We Do
Quantum computing will be a world-changing technology with the potential to unlock powerful advances in medicine, energy, finance and beyond. At PsiQuantum, we’re focused on building the world’s first useful quantum computer.
A useful quantum computer requires at least 1,000,000 qubits and error correction. We believe photonics is the only path to building a useful quantum computer.
Our team at PsiQuantum is a mix of quantum physicists, semiconductor, systems, and software engineers, system architects and more. Error correction is at the centre of everything we do; and we focus on solving real-world problems.
If you’re interested in joining our team, we are always open to hearing from exceptional people interested in working on one of the defining technologies of our lifetime.
