Staff Software Engineer, Non-Realtime Controllers

About the role

IonQ is seeking a highly technical Staff Software Engineer to join the non-realtime controllers team in Oxford. You will work in a cross-disciplinary environment to build and operate the software that controls the hardware supporting quantum computers, including cryogenic systems, lasers, and vacuum pumps. This is a hands-on role focused on deep hardware integration, framework development, and ensuring the reliability of services running on general-purpose Linux hardware.

Responsibilities

• Take on our most demanding device integrations, and do the deep diagnosis of problems that only appear against real hardware in a live lab.
• Remove whole classes of failure across the fleet, rather than instances of them.
• Improve the shared framework yourself, and bring the existing controllers along with each change.
• Build the tooling, simulators and test infrastructure that let the whole team move faster.
• Evolve how our services are deployed and operated as the fleet grows, and make the fleet observable enough that problems are found early.
• Raise the bar of everyone around you through the code you write and the reviews you give.

Required skills

• Systems engineering
• Rust
• Async programming
• gRPC
• REST
• SCPI
• Modbus
• Serial
• Ethernet

Benefits

• IonQ stock options
• Annual performance bonus
• Generous annual leave
• Private medical insurance
• Dental insurance
