IonQ is the world's leading quantum computing platform and merchant supplier, delivering integrated quantum solutions across computing, networking, sensing, and security. The company recently achieved 99.99% two-qubit gate fidelity, setting a world record in quantum computing performance, and serves major customers including Amazon Web Services and AstraZeneca.
We are seeking a Systems Software Engineer to join the Runtime Software team at our Oxford facility. In this role, you will work directly with experimental scientists to implement real-time control system behaviors and provide the abstractions they need for their experiments. You'll contribute to the team's mission of enabling science teams to experiment with and improve the primitive operations that enable quantum computation, building toward fault-tolerant quantum systems.
You will play a critical part in shaping the core Rust libraries and execution environment that transform our hardware into a functional quantum computer, supporting the development of the world's most advanced quantum systems.
Key responsibilities include:
- Collaborating with scientists to understand their experimental requirements
- Interfacing with system orchestration, non-realtime control, and compiler teams to ensure seamless integration with the broader software architecture
- Implementing drivers for various real-time control devices
- Producing tooling that enables rapid and confident iteration by internal users
- Developing the execution environment for user programs running on quantum systems
- Continuously improving the APIs used by internal teams
You will develop abstractions over real-time control hardware, supporting the delivery of a control system capable of repeatedly and reproducibly driving ions with nanosecond-level precision. The role requires balancing fast iteration with system scalability, directly contributing to the success of building utility-scale quantum computers.
