Its offerings include the most energy-efficient quantum computers for data centers, full-stack quantum computing solutions accessible via the cloud, and algorithm access services for academic and industrial customers.\nFollowing a pragmatic, step-by-step roadmap, Quandela has been deploying industrial-grade systems since 2023 while developing future generations of fault-tolerant quantum computers capable of scaling through the integration of thousands of photonic components. Quandela is committed to making quantum computing accessible to all in order to address the most complex industrial and societal challenges.\nLearn more at: Quandela | Leading Photonic Quantum Computing Solutions\nOur ambition is to build large-scale fault-tolerant quantum computers capable of solving problems beyond the reach of classical computation.\nGetting there will require several generations of intermediate architectures. Choosing the right ones means understanding what can be built, what these systems can compute and how efficiently they can do so.\nAbout this position:\nYou will join Quandela’s Quantum Information team within Architecture, working on the evaluation and design of our near- and mid-term quantum architectures.\nYour role will sit between quantum theory, computational capability and real hardware constraints. You will develop methods to evaluate architecture concepts, understand their performance and limitations, and help guide future architecture choices.\nDepending on your background, you may draw on complexity theory, quantum learning theory, quantum-system characterisation, benchmarking or related areas. You will work closely with our Device Physics, FTQC and Q.Algorithms Team.\nRequirements\nWhat you'll do:\nAs a Quantum Information Scientist working on Architecture & Performance, you will:\nEvaluate and compare the capabilities and limitations of near- and mid-term quantum architectures. \nDraw on methods from complexity theory, benchmarking, characterisation and related fields to assess different architecture designs. \nIncorporate realistic noise, native operations and physical constraints into your analyses. \nInvestigate when and how different architectures could provide meaningful computational capabilities or advantages. \nDevelop scientific models and numerical tools to explore architecture-performance trade-offs. \nStudy how architecture choices interact with algorithms, resource requirements and QEC strategies. \nProgressively propose and lead new research projects around architecture design and performance. \nYou will work across our Architecture team and Algorithms and Applications team, connecting questions from the physical layer to computational capability and potential applications.\n-\nHow you'll grow:\nDuring your first 3-6 months\n Become familiar with Quandela’s technologies, architecture roadmap and ongoing research while contributing to existing evaluation and performance studies.\nWithin 1 year\n Take increasing ownership of architecture studies, compare different concepts and bring your own scientific perspective to the team.\nLonger term\n Lead exploratory research projects, propose new architecture directions and contribute to shaping Quandela’s future architecture roadmap.\n--\nWhat we're looking for:\n We are looking for a scientist with a strong theoretical background in quantum computing, scientific autonomy and an interest in connecting different layers of the quantum-computing stack.\nMust-have\nPhD in Quantum Information, Quantum Computing, Physics, Mathematics, Computer Science or a closely related field. \nStrong expertise in one or more relevant areas, such as quantum complexity theory, quantum learning theory, quantum-system characterisation, performance analysis or quantum algorithms. \nExperience connecting theoretical or computational questions with realistic implementation, hardware or experimental constraints. \nAbility to assess the capabilities and limitations of quantum systems or architectures. \nExperience with scientific modelling, numerical simulation and Python-based scientific computing. \nScientific autonomy and ability to structure open-ended research problems.\nCollaborative and personable, with the ability to communicate ideas clearly to people from other fields of expertise. \nProfessional English. \nImportant, but you can grow here\nQuantum Error Correction and early fault-tolerant architectures.\nHardware-aware algorithm or architecture design. \nQuantum benchmarking and performance metrics. \nNoise modelling. \nResource and computational-cost analysis. \nCollaboration with experimental or hardware-oriented quantum-computing teams. \nBonus\nQuantum compilation or native-gate-aware circuit design. \nPhotonic quantum computing. \nResource estimation. \nExperience comparing quantum approaches against strong classical baselines. \nPrevious ownership of collaborative research projects.\nYou do not need to cover every topic above. We welcome both candidates with postdoctoral or equivalent industrial R&D experience and strong recent PhDs demonstrating scientific autonomy.\nBenefits\nJoin a growing quantum-computing company and contribute directly to the research behind future generations of quantum architectures.\nExplore open scientific questions grounded in real hardware constraints. \nWork across Quantum Information, Device Physics, FTQC and Algorithms. \nTake ownership of broad and exploratory research projects. \nContribute to the scientific directions of a growing team. \nPlus:\nCompetitive compensation aligned with your experience and level of responsibility. \nCompany savings plan.\n100% health coverage through Alan. \nTransport reimbursement or sustainable mobility bonus. \nSwile meal vouchers. \nAccess to Gymlib. \nProcess\nTalent Acquisition interview, 30-45 min\nInterview with Quantum Information hiring manager, 30-45 min\nPresentation of previous research work and discussion with members of the theory team \nReference checks \nTechnical discussion based on a scientific paper or research topic\nOffer\nFor the technical exercise, you may be asked to explore scientific material outside your direct area of expertise and discuss how you would connect it to a broader architecture problem.","description_format":"text","description_chars":6347,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"phd","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Quantum
