Quantum Computing Jobs

• Oxford
• Hybrid
• Mid-level

Builds the control plane that schedules quantum programs, calibration routines and customer workloads onto trapped-ion hardware, arbitrating exclusive access and streaming results. Owns persistence, data models and migrations, plus tests and harnesses run against real machines and simulators. Works in Rust, PostgreSQL and gRPC alongside runtime, systems and operator teams.

• Senior

Hands-on staff engineering role building and operating the control plane that schedules, calibrates and records work across a fleet of trapped-ion quantum computers. You'll write Rust services handling scheduling, exclusive hardware access, result streaming and data durability, working with runtime, systems and operations teams. Deep diagnosis of live-system failures and setting service boundaries are central.
