Technical Assistent / Research Technican in Organoid Technologies (f/m/d), full-time

to join our team at the earliest possible date. The position is initially limited until .

The Core Facility Organoids is a central service and research infrastructure dedicated to the establishment, expansion, biobanking, quality control, and functional characterization of patient-derived organoid models. These three-dimensional cultures are generated from human tumor and non-tumor tissues and closely reflect key biological features of the original patient material.

Our facility supports translational reearch projects across the Medical Faculty and beyond, with a particular focus on patient-dericed organoid models, living biobanking, and functional assays. The successful canditate will become part of a small, highly motivated team working at the interface of research, clinical translation, and core facility service.

The position offers close interaction with the institute of the Care Facility Head, Prof. Alexander Kleger, namely the Institute of Molecular Oncology and Stem Cell Biology (IMOS; It is also embedded in the organoid-focused graduate research training programme Org-Boost ( providing excellent opportunities for collaborative work and direct access to cutting-edge organoid-based research.

Your tasks:

• Establishment, expansion, maintenance, and cryopreservation of patient-derived organoid cultures from primary human material
• Preparation and execution of organoid-based assays, including drug screening and viability/toxicity readouts
• Routine preparation of media, reagents, plates, and assy materials
• Documentation of sample processing, culture status, QC steps, experimental workflows, and biobanking inventory

We offer:

• Thorough hands-on training in patient-derived organoid technologies
• Work in a highly motivated and collegial core facility team
• A modern and clinically relevant research environment at Ulm University
• Involvement in exciting translational oncology and living biobank projects using patient-derived organoid models
• Compensation in accordance with the TV-L collective bargaining agreement (TdL: TV-L) inpay grade E8 (Entgelttabelle TV-L.pdf). Your specific pay grade will be determined based on your qualifications and the duties you will perform. The applicable experience level is based on your relevant professional experience.
• Attractive public-sector employment benefits, including corporate benefits and employee offers of Ulm University.

Your profile:

• Completed vocational training as a BTA/MTA, biotechnology assistant, or comparable qualification; alternatively, a Bachelor’s degree in a relevant life-science field. (A Master’s degree or PhD is not required.)
• Experience in mammalian and sterile cell culture; experience with 3D models, organoids, spheroids, or primary human material is an advantage.
• Practical experience with viability/toxicity assays, molecular biology techniques, or structured sample documentation is welcome.
• A careful, reliable, well-organized, and proactive working style, with the ability to follow SOPs and support troubleshooting of routine experimental workflows.
• Good communication skills, good written and spoken English, and willingness to work with human patient-derived material; German language skills are an advantage.

Previous experience with organoid cultures is welcome but not mandatory. Thorough training will be provided at the beginning.

Ulm University seeks to increase the proportion of women in research and teaching and therefore particularly encourages qualified women to apply. Applicants with severe disabilities and persons with equivalent status will be given preferential consideration if equally qualified. We welcome applications from all people regardless of gender, age, origin, disability, or other personal characteristics.
