Senior Vacuum System Engineer - PsiQuantum

We believe quantum computing will change everything.  It will have the power to transform the foundations of giant industries that rely on intensive computation.  PsiQuantum is on a mission to build the world’s first useful quantum computer, capable of delivering these transformative results.  We know that means it will need 1 million qubits, error correction, 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 is uniquely positioned to deliver on the promise of quantum computing years earlier than our competitors
Our architecture is based on photonics which gives us the ability to produce our components using existing high-volume semiconductor manufacturing processes, the same processes that are today producing billions of chips for telecom and consumer electronics applications
Since photons don’t feel heat, we can take advantage of existing cryogenic cooling systems, the kind that have been operating at facilities like the Stanford Linear Accelerator (SLAC).  And because photons are in fact light, they can move between subsystems at tremendous speed using standard fiber connectivity.Our team is building a utility scale quantum computer and the software tools needed to build fault tolerant quantum applications
We’re a highly motivated and collaborative group focused on a singular goal - building the world’s first useful quantum computer on the fastest path possible. There’s much more work to be done and we are looking for exceptional talent to join us on this extraordinary journey! Job Summary:The cryogenic engineering department is hiring a vacuum system engineer who will be heavily involved in the quantum computer design
