DESY, with more than 2900 employees at its two locations in Hamburg and Zeuthen, is one of the world's leading research centres. Its research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. In this way, DESY contributes to solving the major questions and urgent challenges facing science, society and industry. With its ultramodern research infrastructure, its interdisciplinary research platforms and its international networks, DESY offers a highly attractive working environment in the fields of science, technology and administration as well as for the education of highly qualified young scientists.
The DESY group "Information Technology" (IT) is participating in a variety of high‑profile national and European projects, evaluating new and innovative IT technologies. One of the key challenges at DESY is preparing the IT infrastructure for the construction and operation of PETRA IV, the next-generation synchrotron. To ensure a fast ramp-up phase and cost- and time-efficient operations, AI-driven solutions will be integrated across all areas of the supporting infrastructure. This includes administration, design and construction offices, as well as scientific laboratories. To drive these efforts, DESY IT is establishing a dedicated AI team, composed of experts in AI and computing infrastructure. While all team members will bring a broad range of skills, this particular position will focus on developing and optimising LLMs.
- Develop LLM-based prototypes, conducting requirements analysis, identifying use cases, implementing solutions with DESY-internal and external data sources, and optimising/fine-tuning LLMs accordingly
- Design and implement technical security measures, considering technical requirements, legal frameworks, and coordination with relevant stakeholders (e.g. data protection)
- Provide high-level consulting for potential and pilot users, including 3rd‑level support for deployed LLM-based services
- Document the IT‑AI infrastructure and ensure transparency and maintainability of the implemented solutions
- Completed scientific university degree in computer science, mathematics or engineering or related subject, or comparable knowledge
- ln-depth knowledge in the development and optimisation of large language models (LLMs)
- Advanced expertise in adapting LLMs to specific application scenarios
- Extensive experience in software development
- Good understanding of the deployment and provisioning of language models
- Good knowledge of operating and configuring Linux-based services and operating systems would be of advantage
- You have a collaborative mindset, the ability to work in an international and interdisciplinary team and feature also a structured and independent manner of working
- Good command of German, both written and spoken, would be of advantage
