The ambition is for that to run without a person in the loop: machines that assess their own readiness, call for the calibrations they need, and keep a full history of how they were tuned. You'd work closely with the runtime team who own real-time control, the systems teams who build and maintain our quantum computers, and the operators and scientists who run them.

This is a hands-on engineering role and stays that way as you grow in it. You'll play an important part in shaping the services that support our work in building the world's most advanced quantum systems. Previous exposure to quantum systems is not required.

What you'll be responsible for:

This is a hands-on engineering role, balancing delivery of your own areas with support for the teams and scientists who depend on them.

Key responsibilities include:

• 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 rather than specific to one.
• 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.

What you'll need:

To be successful, you will need experience building stateful services that stay correct under failure, and a track record of changing a load-bearing system while people depend on it. We're looking for someone who can own a problem area with little supervision and contribute effectively within a fast moving, highly technical team.

You'd be a great fit with:

• Strong systems engineering skills. Our System Orchestration layer is written in Rust, so either solid Rust experience or deep proficiency in another systems language and the appetite to work in a Rust codebase, including async programming.
• Experience designing and operating networked services (such as gRPC or REST), with a real grasp of error handling, observability and failure modes.
• Real experience with a relational database as a source of truth - schema design, migrations against live data, and transactions. We use PostgreSQL.
• A track record of getting lifecycle and concurrency right: state machines, timeouts, leases, retries, and the failure modes that only show up under load.
• Experience with a scheduler, workflow engine or job queue - Temporal, Airflow, Celery, Slurm, or one you built - or with event-driven systems that react to changes in state.
• A habit of settling design questions in writing, with options weighed as peers.
• Comfort owning the production behaviour of what you build, not just its correctness in test.
• Excellent communication skills both within software and across disciplines.
• An interest in helping other engineers get better at the craft, without wanting to stop building yourself.

Additional useful experience would include:

• Running containerised services in production, Kubernetes, distributed tracing, closed-loop systems that act on measured state, and scientific computing or research facilities.
