EUR Quantum Software Engineer H/F ## Description We are looking for a Quantum Software Engineer to develop the future software stack for controlling utility-scale quantum computers. At the interface of the theory and engineering teams, this ambitious project aims to develop internal tools to streamline the operation of logical quantum circuits on Quandela's spin-photonic quantum computers., Develop a new compilation stack translating high-level quantum circuits into hardware-aware pulse schedules optimized for our photonic quantum computers. - Drive long-term architectural strategy, technical roadmap, and cross-organizational alignment. - Contribute to the development of a digital twin, receiving hardware instructions to simulate the behavior of our future QPUs. - Stay up to date with the latest developments in quantum software. How You'll Grow: - 3 months. By the end of the first quarter, you are expected to have a grasp over Quandela's roadmap and specific approach to quantum computing. You understand how user operations are currently compiled to machine instructions and how that is expected to evolve - 6 months. By the end of the first semester, you have a firm understanding of Quandela's technology and are already a key contributor to the compiler codebase for the near future - 12 months. You have a long-term vision over the quantum software's activities, and are the owner of one or more work packages for strategic projects., Competitive salary, flexible based on your experience Profit-sharing & company savings plan100% health coverage (Alan)50% transport reimbursement or sustainable mobility bonusMeal vouchers (Swile), Gymlib fitness supportChildcare assistance & referral bonuses (€1,000-€2,000)What we offer: A meaningful role with real ownership, from day oneA team eager to collaborate and grow with youA hybrid work model (3-4 days/week onsite in Massy, 1 day in Paris or 1 to 2 days remotely)Daily exposure to the entire quantum stack - from high-level APIs to low-level firmware, and everything in between.
