Lead Quantum Software Engineer (m/f/d)
The Schwarz IT supports the entire digital infrastructure and all software solutions of the companies of the Schwarz Group. It is therefore responsible for selecting, providing and operating as well as further developing IT infrastructures, IT platforms and business applications. In order to optimally support the departments through IT solutions in their business processes, the Schwarz IT takes up the requirements of the departments in consultations and works together with these professional and efficient IT solutions. In the Black Quantum Innovation Lab (SQIL), we are working to extend this claim to Quantum Computing for the companies of the Black Group and other customers of the Black Digits. We are looking for you to make our ambitions come true together with us. As a Lead Quantum Software Engineer, you will take the overall technical lead in the development of our new Quantum Software Stack (QSS). The stack is intended to enable the processing of use cases defined in common quantum SDKs (such as Qiskit, Qrisp or PennyLane) by the efficient and robust interlocking of cloud-native compute in conjunction with the quantum hardware (QPU) to be connected. Based on common SOTA approaches, you define architecture, control integration into our existing STACKIT cloud platform and manage the strategic transfer of research-related open source code into industrial standard. .
