Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before. Location: This role is based out of our College Park, MD, Boulder, CO, or Bothell, WA offices. We offer a hybrid work model, allowing for remote work two days per week. Travel: Up to 5% Job ID: 1781 The Role: We are looking for a Senior Full Stack Software Engineer for Application Engineering . As a Software Engineer on the Applications Engineer team, you'll be part of a cross-functional team whose mission is to deliver real-world applications and deliver value from the jump forward in computing that quantum solving represents. We don't just build the world's best quantum computers - we apply cutting-edge quantum tools to real-world problems. Until this year, our team for Applications Research has been building prototypes and doing research, by working closely with our customers. Our new department, Applications Engineering, transforms those prototypes and research into applications for broad use. Our work makes those innovations available to more people and businesses; as libraries, as APIs, and ultimately as whole SaaS applications. Our Application Engineering team has a commitment to engaging user experience and showing quantum advantage, not just talking about it. We are especially focused on clearly communicating the value of hybrid computing, and making clear outputs to visualize domain specific problems. It’s a chance to shape how quantum computing is conceptualized in contrast to classical computing To support that goal and lay the groundwork for future quantum-enhanced services, this role will also help polish our internal tools, APIs, and integrations.

What success looks like: In your first few months, you'll have onboarded across our R&D codebases, started shipping fixes and reviewing scientist contributions, and identified the biggest stability and observability gaps to tackle. You act as a trusted partner to the scientists on the team: helping them write and structure code, supporting their tooling and documentation needs, running code reviews focused on software quality (organization, readability, maintainability), and flagging cases where deeper science-related review might be needed. No physics or quantum background required, but genuine interest in supporting research work is essential. By the end of your first six months, you'll own the SDLC health of at least one major codebase, with measurably improved observability and faster diagnosis of production issues. By the end of your first year, you'll be a recognized technical leader on the team, having driven at least one cross-cutting initiative that improved stability or contributor experience across our stack, and actively mentoring other engineers or scientist contributors.

Our quantum computing services are available through all major cloud providers, while we also meet the needs of networking and sensing customers across land, sea, air, and space. IonQ is making quantum platforms more accessible and impactful than ever before. Location: Oxford, UK Office commitment: Hybrid 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 Senior Software Engineer for our non-realtime controllers team who will thrive in our dynamic cross-disciplinary environment. You will 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 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. Responsibilities : 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. Requirements: 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. Benefits Be part of a team that’s shaping the future of quantum. We offer more than just a role, you’ll join a world class community of scientists, engineers and innovators working to unlock the full potential of quantum computing. We offer a range of benefits, including opportunities to further your career alongside industry leaders, a competitive salary with IonQ stock options, an annual performance bonus, generous annual leave, flexible hybrid working, private medical and dental insurance for you and your family, and much more. Join us and be part of the future of quantum computing. We’re proud to be an equal opportunity employer and welcome applicants from all backgrounds.
