(Senior) Research Scientist Tensor Networks - flaQship (all genders)

The »Digital Business « research group at the Fraunhofer Institute for Industrial Engineering IAO is working on national and international research, development, and consulting projects to harness the potential of quantum computers for business and society.

The Fraunhofer Lab for Quantum Computing Stuttgart Heilbronn, , unites the expertise of Fraunhofer IAO and IPA under a shared vision. Bringing together researchers from physics, mathematics, computer science, communication, economics, and political science, along with leading professors, we drive excellence in research, agile strategies, and cross-functional collaboration — shaping the future of quantum computing.

We are seeking a highly skilled and motivated (Senior) Quantum Scientist to join our Hybrid Computations research area. This role will focus on leading design, development, optimization and productization of tensor-network based tools with core applications in quantum simulations. The ideal candidate has a strong foundation in tensor networks, a solid understanding of quantum mechanical systems and software development experience, as well as keen interest in quantum computing.

You will work closely with quantum physicists, researchers, and engineers to translate theoretical concepts into robust, scalable, and maintainable software systems and coordinate the dissemination of research results through accessible software tools.

Be part of change

• Develop new tensor-network based methods for applications in the simulation of quantum mechanical systems and machine learning
• Collaborate with researchers and domain experts to translate scientific requirements into technical implementations
• Professionalize and optimize algorithms and software packages with respect to performance, scalability, and reliability
• Write clear, maintainable documentation and contribute to technical design reviews
• Disseminate results in research papers and conferences

What you contribute

• You hold a Master’s degree in Computer Science, Software Engineering, or a comparable field (a PhD or long-term equivalent practical experience is welcome)
• You have domain expertise in machine learning, quantum many-body systems, or quantum computing
• You have a strong background in the application and development of tensor network applications and enjoy working at the intersection of applied research and emerging technologies
• You are proficient in at least one programming language such as Python, C++, Java, or Rust, have a good understanding of data structures, software design principles, and version control systems (e.g. Git), and are comfortable working in Linux/Unix environments
• You have experience with agentic AI tools, LLM-assisted development, and workflow automation
• Ideally, you have experience with or a strong interest in quantum computing frameworks (e.g. Qiskit, Cirq, PennyLane, Q#), high-performance computing, parallel programming, GPU acceleration, or cloud and container technologies (Docker, Kubernetes)
• You enjoy solving complex problems, work reliably in interdisciplinary teams, and communicate confidently in English; German language skills are an advantage but not required

What we offer

• You will work in an interdisciplinary, international research environment with direct access to leading experts, state-of-the-art infrastructure, and strong industry partnerships
• You will contribute to one of Germany’s leading applied quantum computing initiatives, working closely with national and international partners at the forefront of the field
• Team-oriented work and an excellent working atmosphere
• A fair and transparent remuneration system with individual, performance-related remuneration components and profit sharing
• A comprehensive range of training and qualification opportunities
• Flexible working hours and the option of mobile working
• Additional benefits (including discounted Germany-wide rail ticket, company cell phone, also for private use, and company pension plan)

We value and promote the diversity of our employees' skills and therefore welcome all applications – regardless of age, gender, nationality, ethnic and social origin, religion, ideology, disability, sexual orientation and identity. Severely disabled persons are given preference in the event of equal suitability. Our tasks are diverse and adaptable – for applicants with disabilities, we work together to find solutions that best promote their abilities.

The position is initially limited to 2 years. Long-term continued employment is the goal.

The weekly working time is 39 hours. This position is also available on a part-time basis.

Remuneration up to TVöD pay group 13 (dependent on qualifications). Appointment, remuneration and social security benefits based on the public-sector collective wage agreement (TVöD). Additionally Fraunhofer may grant performance-based variable remuneration components.

With its focus on developing key technologies that are vital for the future and enabling the commercial utilization of this work by business and industry, Fraunhofer plays a central role in the innovation process. As a pioneer and catalyst for groundbreaking developments and scientific excellence, Fraunhofer helps shape society now and in the future.
