Job summary

IonQ's Oxford team is seeking a Senior Software Engineer to join the System Orchestration group. You will build and operate software that calibrates, schedules, and records quantum computer activity, enabling continuous, productive workloads across the fleet.

This hands-on role partners with runtime and systems teams to ensure reliable operation of quantum hardware, with increasing autonomy and robust observability.

Responsibilities

• Own a service or subsystem end to end - API design, implementation, rollout and ongoing operational health.
• Build closed-loop behaviour that acts on measured system state without a person in the loop.
• Design state machines and their persistence together, so that what survives a restart is a decision rather than an accident.
• Make our services behave correctly under concurrency and partial failure.Move live systems onto new behaviour without losing data or interrupting work in flight.
• Evolve our APIs, and bring the clients that depend on them along.
• 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.
