<div>IonQ is developing the worlds 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. </div>We are looking for a Senior Physicist. As a physicist on the Integrated Photonics team, 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 assist with the construction and operation of a new ion-based testbed for integrated photonics at the IonQ Basel location. You will spend time getting up to speed with the operation of IonQ quantum computers and testbeds with the photonics testbed team.  You will then assume a full-time, on-site role at the Basel office, where you will be responsible for coordinating with teams for assembly instructions and ultimately building and qualifying the new system.  You will work closely with the testbed team in the College Park office, including remote meetings and occasional on-site visits.  As the testbed enters an operational phase, your role will focus more on ion-based testing of integrated photonics technologies.  You will provide critical testing data to the integrated photonics team that will enable us to produce new technologies that will increase the capabilities of IonQ’s quantum computers.
