Senior Mechanical Engineer

Quantum computing holds the promise of humanitys 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 todays 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 dont 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 computings potential impact and the need to scale this technology to unlock that potential. And we wont 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.

Theres much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!
