Staff System Architect

IonQ, Inc. is a publicly traded quantum‑technology company that builds and supplies integrated quantum solutions for computing, networking, sensing and security. Its flagship hardware, the IonQ Tempo, powers applications ranging from drug discovery to financial modelling, and the firm operates from a headquarters in College Park, Maryland with additional sites across the United States, Europe and Asia. The opening position is for a Staff System Architect who will devote their efforts to IonQ's Superconducting Nanowire Single‑Photon Detector (SNSPD) product line. The architect will steer the technical architecture and roadmap for the next‑generation rack‑mountable SNSPD platform, ensuring that hardware, software and integration components evolve in a coordinated fashion to meet product vision and market demands. Day‑to‑day, the architect will be embedded in the development process for the SNSPD platform, which serves quantum‑computing, networking and sensing markets. Responsibilities include shaping scalable, maintainable system designs that enable autonomous, round‑the‑clock detector operation, translating product requirements into clear system specifications, and overseeing the end‑to‑end architecture to keep it aligned with a shared long‑term vision. The role sits at the crossroads of quantum photonics, cryogenic systems engineering and embedded‑systems design, requiring close collaboration with cross‑functional teams to deliver a coherent technical solution. The posting does not enumerate any mandatory qualifications, years of experience, language proficiency, certifications or specific tools that candidates must possess. Consequently, there are no explicit must‑have requirements listed for this role. While no formal prerequisites are stated, the description highlights several attractive aspects of the position. The role is central to a cutting‑edge cryogenic photon‑detection platform that underpins IonQ's quantum‑technology roadmap. Working within a globally distributed organization, the architect will interact with teams located in multiple U.S. states as well as Europe and Asia, offering exposure to a diverse set of perspectives and expertise. IonQ's rapid growth, recent achievements in two‑qubit gate fidelity and world‑record quantum‑computing performance suggest a dynamic environment where technical leadership can have a tangible impact on the future of quantum hardware.
