You will own areas of the hardware control surface end to end, from the device protocol up to a service running reliably across our fleet. This is a hands-on engineering role and stays that way as you grow.

A working quantum computer is far more than the ion trap and its real-time control electronics. It depends on a fleet of supporting hardware, including cryogenic compressors, vacuum pumps, power supplies, lasers, temperature controllers, wavemeters and cameras, that has to be kept observable, controllable and reliable. The timing-critical operations such as gate waveforms and ion transport run on dedicated real-time FPGA systems, while this team owns everything that does not need hard timing guarantees. These services run on general-purpose Linux hardware and must be rock-solid, because a failed compressor or an un-noticed pressure drift takes a whole machine offline.

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 working with Linux based systems and interfacing with hardware, and a track record of making software behave well against unreliable external dependencies. We're looking for someone who can own a problem area with little supervision and judge where robustness is worth the effort.

You’d be a great fit with:

• Strong systems engineering skills. Our controllers are 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.
• Experience of hardware and instrument protocols and interfaces such as SCPI, Modbus, serial and Ethernet.
• Comfortable owning the production behaviour of what you build, not just its correctness in test.
• Excellent communication skills both within software and across disciplines, and an interest in helping other engineers get better at the craft without wanting to stop building yourself.
