Staff Software Engineer, Non-Realtime Controllers at IonQ, Oxford, England, United Kingdom. A lead-level full time position in the Compute - Engineering team, listed under software engineering. The Role Quantum is now, and it's built here. Oxford Ionics, now part of IonQ, is pioneering the next generation of quantum computing. Using our world-leading trapped-ion technology, we're building the most powerful, accurate and reliable quantum systems to tackle problems that today's supercomputers cannot solve. We're looking for an enthusiastic and highly technical Staff Software Engineer for our non-realtime controllers team who will thrive in our dynamic cross-disciplinary environment. You'd be working closely with our skilled software engineers, our systems teams who operate the physical quantum computers, and our world-leading quantum scientists to build and operate the software that controls the hardware surrounding our quantum computers. Previous exposure to quantum systems is not required. You will take on our most demanding hardware integrations and the framework work that makes every other controller better. This is a hands‑on engineering role: you would be the most experienced engineer writing controllers, not the one directing others to write them. 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. Responsibilities This is a hands‑on engineering role. Your influence comes from the code you ship and review, and from the problems you take off everyone else's plate. Responsibilities Take on our most demanding device integrations, and do the deep diagnosis of problems that only appear against real hardware in a live lab. Remove whole classes of failure across the fleet, rather than instances of them. Improve the shared framework yourself, and bring the existing controllers along with each change. Build the tooling, simulators and test infrastructure that let the whole team move faster. Evolve how our services are deployed and operated as the fleet grows, and make the fleet observable enough that problems are found early. Raise the bar of everyone around you through the code you write and the reviews you give. #J-18808-Ljbffr
