IonQ is hiring a systems software engineer for its Runtime Software team in Oxford, working directly with experimental scientists. The role is building the real-time control layer and execution environment that turn a collection of hardware into a quantum computer: abstractions over real-time control hardware, device drivers, internal tooling and APIs, written largely in Rust. The posting asks for expert systems-programming skills, comfort with low-level code, rapid iteration, cross-disciplinary communication, code review and testing. It emphasises nanosecond-precision control; no salary is stated.
