Software Engineer, System Orchestration

About the role

The System Orchestration team is responsible for building the software that calibrates quantum computers, schedules workloads, and maintains system records. You will own features end-to-end, from API development to deployment, ensuring quantum systems remain productive and within performance specifications. This role involves working closely with runtime, systems, and scientific teams to build a robust control plane for a fleet of quantum computers.

Responsibilities

• Build and extend the services that schedule work on our systems and keep the record of it.
• Build the mechanisms that decide when a system needs re-tuning, and get those calibrations run.
• Own what we persist: the data model, its migrations, and the code that reads and writes it.
• Produce the tests and harnesses that let our code be exercised against real hardware and against simulators.
• Work with the systems teams to roll releases out across the fleet and support them once they are running.
• Improve the observability of the code you ship.
• Take part in code review, and improve the APIs our internal users depend on
