PsiQuantum is on a mission to build the world’s first fault tolerant quantum computer capable of tackling today’s most intractable computational challenges to deliver transformative results. We know that means it will need roughly 1 million qubits and will be building scale in size.

Quantum computing is expected to deliver breakthroughs for today’s still impossible computational tasks. By harnessing the laws of quantum physics, quantum computers can provide exponential performance increases over even the most powerful of today’s conventional supercomputers offering the potential for extraordinary advances across a broad range of applications 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. Our architecture is based on photonics which gives us the ability to produce our components using high-volume semiconductor manufacturing processes, the same processes that have been applied in telecommunications and data center applications for decades. Since photons don’t feel heat, we can take advantage of existing cryogenic cooling systems, the kind that have been operating at facilities like Stanford Linear Accelerator (SLAC) since 2018. And because photons are basically light, they can move between subsystems using standard fiber connectivity, without the need for transduction in and out.

Our team is working across the full stack of quantum computing, from quantum architecture to photonic chip manufacturing, advanced opto-electronic packaging, hardware systems design, quantum algorithms and software tools, and cryogenic cooling. We’re a highly motivated and collaborative group focused on a singular goal - building the world’s first Fault Tolerant Quantum Computer on the fastest path possible.

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

Job Summary:

Quantum computing promises to solve many important problems that could never be solved on any conventional computer. At PsiQuantum, we’re building a general purpose silicon photonic quantum computer to tackle these very problems.

We are looking for an energetic, highly motivated Photonics Engineer who will be responsible for the design, optimization, integration, and validation of novel photonic structures, devices, and subsystems for a linear optic quantum computer (LOQC).

We’re looking for a creative and innovative individual with strong fundamentals in the design, optimization, layout, and fabrication of optical devices. This role is focused on leading a group that is pushing the boundaries of high-performance integrated photonic components and circuits. The role requires excellent python skills, experience with commercial electro-magnetic simulation packages, and experience with photonic optimization techniques. Experience with python based layout tools and foundry tapeouts are highly desirable.


  • Leads the development of passive photonic components.
  • Interacts with device, hardware and software design teams to assist in overall development of Photonics and Quantum Optics photonic systems and devices.
  • Leads the development of simulation automation techniques and infrastructure to support photonic device design, model development, and performance validation.
  • Leads the development of a photonic device library and process design kit (PDK) for passive photonic components.
  • Supports foundry tapeouts with photonic device design, design of experiments, layout, device validation, data analysis, failure mode analysis, and troubleshooting.
  • Provides multi-disciplinary support to component and systems teams by resolving technical issues associated with components, parts, products, or systems.
  • Applies quantitative analysis in determining root cause of highly technical problems and proposes, develops and implements solutions for corrective action.



  • PhD or equivalent in Electrical, Computer Engineering, Material Science, Physics.


  • 10 years of relevant work or academic research experience in integrated photonics.

Knowledge, Skills and Abilities:

  • Strong leadership and organizational skills
