Engineer in radiation protection for PETRA IV (m/f/d)

For Hamburg we are looking for: Engineer (w/m/d) Remuneration group 12 | Restricted: first 2 years with option on determination | Start: earliest possible | ID: MMA035/2026 | Application deadline: 11.09.2026 | Full time/part time | Mobile work possible The Deutsche Elektronen-Synchrotron DESY with more than 2900 employees is one of the world's leading research centres in Hamburg and Zeuthen. Research focuses on decoding the structure and function of matter, from the smallest particles of the universe to the building blocks of life. DESY contributes to solving the major issues and pressing challenges of science, society and the economy. With state-of-the-art research infrastructure, interdisciplinary research platforms and international networking, DESY has a highly attractive working environment in the scientific, technical and administrative field, as well as for the training of highly qualified young people. An absolute highlight is the large project PETRA IV – one of the most ambitious and innovative research infrastructure projects worldwide. With PETRA IV, a next-generation synchrotron radiation source is created which sets new standards in precision, performance and scientific excellence. The associated construction and infrastructure measures are technically highly complex, internationally visible and offer the unique opportunity to participate in a lighthouse project of global importance. This results in demanding challenges of both scientific and technical nature. More information about PETRA IV can be found here: PETRA IV The spectrum of the radiation protection group at DESY ranges from radiation protection physics and right through measurement technology, activation and screening calculations, Monte Carlo simulations to co-designing the safety concepts of the accelerator systems. An essential component for the safe operation of the accelerator systems is the so-called passenger interlock system, which ensures the safe operation of an accelerator. We are looking for support for the design, optimization and testing of passenger interlock systems as well as the implementation of risk assessments for the future PETRA IV accelerator system with regard to the design of the passenger interlock system.

Conception, analysis and optimization of passenger interlock systems Risk assessment of new projects according to legal requirements with the focus on functional safety Organisation and implementation of tests of existing person interlock systems with regard to scientific and technical execution Creation and optimization of test instructions including related documentation Exercise of responsibility and duties as radiation protection officers

Complete technical university studies, engineering, electrical engineering, radiation protection, physics or comparable disciplines or equivalent skills and experience Knowledge of functional safety and measurement technology Knowledge of radiation protection Ideally, experience in handling passenger interlock systems at large accelerators and/or experimental areas at large accelerators High level of autonomy, reliability, care and responsibility Very good knowledge of English and German in word and writing
