IonQ seeks a senior front-end engineer for its Quantum Tools software team in Oxford, working two days a week on site. The role involves building web-based tools for quantum scientists and engineers: information-dense dashboards, system telemetry, calibration views and hardware-control interfaces. The posting asks for TypeScript, HTML, CSS and React experience, plus streaming-data interfaces, interactive charts, large-dataset handling and judgement about rendering performance and SVG/Canvas/WebGL trade-offs. It also calls for working with cross-functional users to turn workflows into concrete graphical tools and maintaining strict testing discipline.
