Come work with the companies building the future!

Sr. Engineer, PIC Platform at PsiQuantum
Palo Alto, CA, US

We are on a mission to build the world’s first large-scale, commercially viable, 1 million-plus qubit quantum computer, powered by breakthroughs in silicon photonics and quantum architecture. We were founded in 2016 by the world’s foremost experts in photonic quantum computing and have assembled a world class team dedicated to bringing the world-changing benefits of quantum computing into reality.

Quantum computing is anticipated to unlock the solution to otherwise impossible computational tasks, with potential impact across all of science and technology. By harnessing the laws of quantum physics, quantum computers are expected to dramatically outperform even the most powerful supercomputers, enabling extraordinary advances across a broad range of applications including climate, energy, healthcare, finance, agriculture, transportation, materials design, and more.

In many areas of scientific and technical inquiry, humanity has reached the limit of what even the most powerful existing (or future) supercomputers can do--but quantum computers are poised to crack problems that are simply out of humanity’s reach with traditional computers.  With applications across climate, healthcare, energy, finance, agriculture, transportation, materials design and more, quantum computing will tackle some of the most urgent practical challenges we face, as well as deliver entirely new industries.

PsiQuantum is uniquely positioned to deliver on the promise of quantum computing. We have already demonstrated that it’s possible to manufacture core quantum components using the standard and scalable manufacturing processes of a world-leading semiconductor fab.

There’s more work to be done and we are looking for exceptional talent to join us on this extraordinary journey!

Job Summary:

PsiQuantum (PsiQ) will hire a senior engineer to develop Photonics Integration Circuits (PIC’s) powering quantum computers.  Supervised by the PIC Platform Engineering Leader, the individual will closely work with optical component design teams, ensuring design for (PIC) integration, DfM, DfT and so on.  Through joint development with our foundry and packaging engineering teams, the PIC team will design PIC’s and deploy through semiconductor fabrication, test, verification and  packaging.  The hired candidate will analyze data, make recommendations for design and manufacturing and support system integration to a quantum computer.

A successful candidate will have demonstrated competence in PIC design, optical component verification, optical circuit validation and teamwork, with adjacent skills in semiconductor fabrication, test and packaging, and system integration.  She or he will embrace our vision for a truly useful quantum computer and thrive in a startup environment focused on bringing this computer to market.
