On the hardware level, remarkable challenges make this journey unique and interesting. At the Quantum Register team, we push the limits of the qubit preparation for computation, enabling scalability, high repetition rate and qubit connectivity, addressing problems such as quantum simulation and quantum error correction codes. We are looking for highly motivated and experienced R&D scientific software engineer / algorithm developer to strengthen our team. You will have a key role at PASQAL to explore, validate, and push to production algorithms that directly improve register performance and integrate into PASQAL's broader software environment. Main responsibilities The ideal candidate will have a strong interest in developing and implementing algorithms that apply concepts from math, physics, statistics and engineering concepts to solve multi-disciplinary problems at the hardware and system level. What you will be doing : * System-level problem solving * Translate hardware constraints, physical principles and system requirements into functional block diagrams, algorithmic architecture, and software interfaces. * Develop a high-level understanding of the algorithm library and interfaces with the broader software stack and hardware systems. * R&D scientific software development and validation * Explore and evaluate algorithmic approaches using simulations, data analysis, and quantitative benchmarking whenever applicable. * Conduct literature reviews and technology watch activities to identify relevant methods and emerging techniques. * Validate software performance using defined metrics and produce test reports * Performance engineering * Profile, benchmark, and optimize runtime and resource usage * Ensure reliability and scalability of implementations. * Experience with vectorized computations on CPU and GPU architectures * Interface software solutions with laboratory or industrial instrumentation when required. * Cross-functional collaboration * Collaborate with software and hardware engineers to integrate algorithms into end-to-end systems. * Present results clearly and adapted to the audiences and document methodologies and system algorithmic architecture. ## Related Videos - [Are Classical Automation Frameworks Dead?
