Job summary

Oxford Ionics, part of IonQ, is looking for a highly technical Senior Software Engineer to join our System Orchestration team in System Software. You will build and operate software that calibrates, schedules, and records quantum workloads across our fleet.

The role is hands-on and requires ownership of device controllers, robust services, observability improvements, and close collaboration with runtime, systems, and science teams. Previous quantum-system experience is not required.

Qualifications

• Experience building stateful services that stay correct under failure.
• Ability to own a problem area with little supervision in a fast-moving, highly technical team.
• Experience with scheduling/workflow systems and asynchronous programming.

Responsibilities

• Own a group of device controllers end to end, covering API design, implementation, rollout and ongoing operational health.
• Make services robust against the ways real instruments fail.
• Bring devices onto our current framework, and roll the result out across the fleet without disrupting running experiments.
• Improve the shared framework where a problem turns out to be common to many controllers.
• Work closely with the systems teams and scientists who depend on these services, and strengthen observability, health checking and alerting.
• Raise the standard of the code around you through review, and bring less experienced engineers on by working alongside them.
