Senior Engineer, Integrated Photonics

Location: College Park, Maryland

Team: Integrated Devices

Type: Full-Time

IonQ is developing the world's most powerful full-stack quantum computer based on trapped-ion technology. We are pushing past the limits of classical physics and current supercomputing technology to unlock a new era of computing. Quantum computing has the potential to impact every area of human society for the better. IonQ’s computers will soon redefine industries like medicine, materials science, finance, artificial intelligence, machine learning, cryptography, and more. IonQ is at the forefront of this technological revolution.


We’re proudly supported by high-quality investors like GV (Google Ventures), New Enterprise Associates (NEA), Amazon, Samsung, Bosch, HP, Airbus, and more.

We are looking for a Senior Engineer, Integrated Photonics. As a Senior Engineer, you’ll be part of a cross-functional team whose mission is to lead IonQ on its journey to build the world’s best quantum computers to solve the world’s most complex problems. In this role, you will focus primarily on developing and utilizing tools for characterization of photonic integrated circuits (PICs) for use in trapped-ion quantum computer systems.  The characterization tools you design, build, and use, and the data you collect, will provide crucial feedback to aid in the design fabrication, and overall development of a new and game-changing photonics technology.   


  • Characterize and validate photonic integrated circuits (PICs) and devices
  • Design, build, and utilize device characterization infrastructure for PICs that operate over a wide wavelength range from the near UV to the near infrared
  • Develop automated PIC characterization capabilities and infrastructure to increase testing throughput
  • Develop device testing and characterization protocols and data analysis tools
  • Develop databases to store raw and analyzed data and results
  • Design and simulate PICs for testing and for integration into trapped-ion quantum computing systems
  • Work within a team of microfabrication engineers, PIC engineers, and quantum computing physicists to improve PIC performance and system impact

You’d be a good fit with: 

  • A PhD in Engineering, integrated photonics, or related field
  • 5+ years of experience in hands-on characterization of photonic integrated circuits (PICs) and devices
  • Experience with free-space and fiber optics for delivery of laser light to PICs
  • Experience designing, building, and using optical testing infrastructure, including automated testing systems
  • Strong programming skills for experimental automation software
  • Strong data processing, visualization, and organizational skills
  • Familiarity with fabrication processes and design constraints for PICs  

You’d be a great fit with: 

  • 3+ years of industry experience
  • Experience with design and simulation of integrated-photonic PICs and devices via Lumerical, COMSOL, or similar
  • Experience with programming in Python
  • Experience working with visible-light laser sources and optics
  • Experience using 3D CAD tools like Autodesk Inventor or Solidworks
