The ideal candidate is someone who is a detail-oriented problem solver with strong teamwork skills.
Responsibilities:
- Design, upgrade, and expand the testing infrastructure for characterizing classical integrated photonics devices and components (passive and active) at chip and wafer level scale, utilizing both room-temperature and cryogenic setups.
- Develop and perform robust testing procedures for component-level characterization.
- Automate the test pipeline, including instrument setup, data acquisition, and analysis, while maintaining high-quality, scalable, and well-tested scripts.
- Conduct characterization using room-temperature and cryogenic setups and provide data-driven feedback to design engineers to improve component performance.
- Collaborate with design, packaging, and system teams to optimize testing features and develop a library of testing structures for platform improvement.
Requirements:
- 3+ years of professional experience in the hands-on characterization of PIC devices or an equivalent combination of education and experience.
- Master or Ph.D. in engineering or related field/discipline or equivalent practical experience.
- Programming experience in a general-purpose programming language (like Python, Matlab, etc.) for test automation.
- Experience with test instrumentation and methods for characterizing classical integrated photonics devices.
- Strong data processing, visualization, and organizational skills.
- Hands-on experience with room-temperature optical test setups
Preferred Qualifications:
- 5+ years of design and characterization experience of classical integrated photonics devices.
- 3+ years of industry experience.
- Familiarity with free-space optics and imaging systems.
- Hands-on experience with cryogenic optical test setups.
- Experience working with laser sources and fiber components.
- Strong programming skills for data analysis and experimental automation software, and experience with version control systems such as git.
- Familiarity with fabrication processes and design constraints for PICs.

US Technical Jobs. The position you are applying for will require access to technology that is subject to U.S. export control and government contract restrictions. Employment with IonQ is contingent on either verifying “U.S. Person” (e.g., U.S. citizen, U.S. national, U.S. permanent resident, or lawfully admitted into the U.S. as a refugee or granted asylum) status for export controls and government contracts work, obtaining any necessary license, and/or confirming the availability of a license exception under U.S. export controls. Please note that in the absence of confirming you are a U.S. Person for export control and government contracts work purposes, IonQ may choose not to apply for a license or decline to use a license exception (if available) for you to access export-controlled technology that may require authorization, and similarly, you may not qualify for government contracts work that requires U.S. Persons, and IonQ may decline to proceed with your application on those bases alone. Accordingly, we will have some additional questions regarding your immigration status that will be used for export control and compliance purposes, and the answers will be reviewed by compliance personnel to ensure compliance with federal law.
