Born from a philosophy of bold innovation, we’ve successfully transitioned quantum computing from an academic dream into a commercial reality. The most exciting thing is that we’re just getting started and we’ve recently closed our £260 million Series C funding round - the largest fundraise ever completed by a quantum computing company in Europe.\nThe Purpose\nAs a Quantum Software Engineer, you'll turn quantum algorithms and research prototypes into robust, production-quality software. You'll bridge the gap between quantum research and classical engineering, building the software foundations that allow quantum workloads to be integrated, compiled, executed, tested and operated reliably as part of larger applications.\nThe Role\nBased in London, you'll work across the quantum and classical software stack, partnering with quantum algorithm specialists, platform engineers, infrastructure teams and application developers.\nYou'll take promising quantum use cases beyond the research prototype-building reusable software components, integrating them with production infrastructure and solving problems across the full execution path, from application code and circuit compilation through to simulators and QPUs.\nThis is a role for an engineer who understands quantum computing but thinks like a software engineer: maintainability, testing, reliability and production readiness matter just as much as getting the algorithm to run.\nWhat You'll Be Working On\nBuild production-quality quantum software components and reusable application functions that can be integrated into wider products and platforms.\nTranslate quantum algorithms and research prototypes into robust, tested and maintainable production software.\nIntegrate quantum workloads with APIs, containerised services, Kubeflow workflows, data services and application execution infrastructure.\nDiagnose complex issues across the full execution path-from Python and application code through circuit compilation, simulation and QPU execution.\nShape technical designs for quantum execution workflows, compilation, runtime integration and hybrid classical-quantum applications.\nApply strong software engineering practices across automated testing, CI/CD, documentation, version control, code review and maintainable design.\nCollaborate across Quantum Algorithms, Platform, Infrastructure and Applications teams to take quantum use cases from concept through to reliable production deployment.\nWhat We're Looking For\nExperience as a quantum software engineer, backed by strong software engineering fundamentals and experience building production-quality software.\nHands-on experience with modern engineering practices including CI/CD, automated testing, code review, version control and Agile/Scrum development.\nGood understanding of quantum computing concepts, including quantum circuits and how parameterised circuits are transpiled and compiled for execution.\nFamiliarity with commonly used quantum algorithms and the ability to translate algorithmic concepts into practical software components and workflows.\nConfidence working across quantum and classical software stacks and bridging the needs of quantum specialists and classical software engineers.\nStrong debugging and problem-solving skills, with the ability to investigate issues across multiple layers of a complex software and execution stack.\nStrong communication skills, including the ability to explain quantum concepts clearly to technical stakeholders with different levels of quantum expertise.\nDegree or equivalent practical experience in Quantum Computing, Computer Science, Physics or a related discipline.\nThe 'Nice-to-Haves'\nExperience developing quantum computing applications for financial services.\nFamiliarity with regulated enterprise environments and evidence-led product development.\nExperience taking quantum research software from prototype into repeatable production engineering workflows.\nExperience with containerised services, workflow orchestration or production data infrastructure.\nA pragmatic, curious approach and comfort working in a fast-evolving technical environment.\nA relevant professional or postgraduate qualification.\nWhy Join OQC\nYou will join a world-class team at the forefront of the next computational era. We offer a culture of bold innovation, the chance to work with unique lab infrastructure, and the opportunity to see your work redefine the limits of computation.\nLearn more about our benefits and positive work culture here: https://oqc.tech/company/careers-at-oqc/","description_format":"text","description_chars":4633,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum Science & Computing","Quantum Computing Hardware"],"lifecycle":[{"event":"open","at":"2026-09-29T19:10:27Z"}],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":46,"reasons":["conf:7","velocity","win:early"],"computed_at":"2026-10-01T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/oqc-quantum-software-engineer","json_url":"https://alion.io/job/oqc-quantum-software-engineer.json","meta":{"generated_at":"2026-10-01T10:46:52Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":2000,"day_limit":5000,"remaining_today":3000,"minute_limit":60,"resets_at":"2026-10-02T00:00:00Z"}}}
