This includes classical and quantum algorithms for graph machine learning, optimization, and quantum simulation use cases. You will bridge research and production engineering: turning algorithmic ideas into robust, maintainable, well-tested software, while ensuring interoperability across the software stack and strong developer experience. Key Responsibilities - Improve performance, reliability, and maintainability of production codebases. - Transfer research ideas from quantum algorithm teams into production-grade code. - Produce structured, documented, tested implementations with strong quality standards. - Ensure interoperability of the application software stack with other libraries. - Actively contribute to the development and productization strategy of the quantum software stack. - Drive strong API UX with clear migration paths, versioning, and breaking-change management. - Support backwards compatibility and deprecation practices. - Promote best practices for benchmark design and statistical rigor. - Contribute to backend/platform engineering topics: job orchestration, reliability, observability. - Support packaging and release engineering, As a Senior Quantum Software Engineer, you will develop, optimize, and maintain PASQAL's ecosystem of quantum solver libraries: libraries featuring algorithms for neutral-atom quantum computers.
