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.

IonQ Insights
What We Do
Quantum computers are a revolutionizing technology — they have the potential to transform business, society, and the planet for the better, and IonQ is at the forefront of this revolution. After over 25 years of academic research, IonQ was founded in 2015 by Chris Monroe and Jungsang Kim with $2 million in seed funding from New Enterprise Associates, a license to core technology from the University of Maryland and Duke University, and the goal of taking trapped ion quantum computing out of the lab and into the market. In the following three years, we raised an additional $20 million from GV, Amazon Web Services, and NEA, and built two of the world’s most accurate quantum computers. In 2019, we raised another $55 million in a round led by Samsung and Mubadala, and announced partnerships with Microsoft and Amazon Web Services to make our quantum computers available via the cloud. In 2020 and 2021, we built additional generations of high performance quantum hardware, added Google Cloud Marketplace to our cloud partner roster and announced a series of collaborations and business partnerships with leading academic and commercial institutions. On October 1st, 2021, IonQ began trading as IONQ on the New York Stock Exchange, making it the world's first public pure-play quantum computing company. We remain hard at work realizing the world-changing potential of quantum computing.
