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 Photonics Device Engineer. As a Senior Photonics Device 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. 


  • Lead an effort focused on the characterization and validation of 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 novel 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 designers, and quantum computing physicists to improve PIC performance and system impact

You’d be a good fit with: 

  • 7+ years of experience in hands-on characterization and design 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 data processing, visualization, and organizational skills
  • Familiarity with fabrication processes and design constraints for PICs 
  • Ph.D. in engineering, applied physics, or related field 

You’d be a great fit with: 

  • Experience with simulations of integrated-photonic devices via Lumerical, COMSOL, or similar
  • Experience working with visible-light laser sources and optics
  • Strong programming skills for experimental automation software
  • Experience using 3D CAD tools like Autodesk Inventor or Solidworks
