Senior PIC Product Engineer

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:

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 seeking an experienced and highly motivated Photonic Integrated Circuit Product Engineer to lead the integration of advanced Photonic circuits and subsystems for our linear optical quantum computer (LOQC). This role is critical to ensure that silicon photonic circuits meet stringent performance requirements at the system level.

As a key contributor, you will collaborate across design, test, systems, and manufacturing teams to derive performance metrics, align calibration strategies, and analyze data across multiple hardware levels. You will play a central role in root-cause analysis, quality evaluations, and performance improvement of photonic hardware. Your work will directly inform PIC design and process by refining the requirements.

We're looking for an out-of-the-box thinker with a strong foundation in optics, materials science, electromagnetics, and nanofabrication-someone who thrives in multidisciplinary environments and is driven to push the boundaries of integrated photonics.

Responsibilities:

• 
  

  Ensure that silicon photonic circuits performance requirements are met at the system level

  
  
• 
  

  Interact with design, test, system, and manufacturing to define performance screens and calibration methods

  
  
• 
  

  Perform statistical data analysis across different hardware levels to characterize and improve performance

  
  
• 
  

  Support FA, quality analysis and evaluation of development, proto, and pilot units

  
  
• 
  

  Drive PIC and subassembly specifications and improvements in product performance during the pilot ramp

  
  

Experience/Qualifications:

• 
  

  M.S. degree + 5+ years' experience or Ph.D. in Electrical Engineering, Photonics, or Physics + 3+ years' experience in photonic integration and manufacturing

  
  
• 
  

  Experience with active and passive silicon-photonics. Working knowledge of device fabrication and materials is desirable.

  
  
• 
  

  Working knowledge photonic test methods

  
  
• 
  

  Ability to perform data and statistical analysis and present data and ideas to a diverse audience

  
  
• 
  

  Team-oriented with the ability to work cross-functionally

  
  
• 
  

  Excellent verbal and written communication skills
