Research Technician Reference number: 2024-0331 * Heidelberg * Vollzeit * Junior Research Group "Epithelium Microbiome Interactions" “Research for a life without cancer" is our mission at the German Cancer Research Center. We investigate how cancer develops, identify cancer risk factors and look for new cancer prevention strategies. We develop new methods with which tumors can be diagnosed more precisely and cancer patients can be treated more successfully. Every contribution counts – whether in research, administration or infrastructure. This is what makes our daily work so meaningful and exciting. ----------------------------------- Our Junior Research Group " Epithelium Microbiome Interactions " (headed by Dr. Jens Puschhof) is seeking a Our junior research group studies how bacteria contribute to cancer development, metastasis and treatment response. Our team includes cancer researchers, tissue engineers, microbiologists, and bioinformaticians working together to help patients by deciphering the functional impacts of bacteria in human tumors. In our projects, we use organoid, organ chip and in vivo platforms to dissect the mechanisms of cancer-microbe interactions. We are looking for a qualified and motivated research technician (BTA, MTA, Biologielaborant or similar) to support in vivo and in vitro experiments on several projects focused on the role of the microbiome in cancer development and progression in our group. Your Tasks The candidate will be trained in and responsible for the generation and maintenance of next-generation patient-derived in vitro culture models including organoids and isolated bacterial strains. The candidate will furthermore take care of research animals following standard operating procedures and according to animal welfare regulations. Additionally, the candidate will learn and apply a variety of laboratory techniques, such as DNA/RNA isolation and purification, protein extraction, genotyping by PCR, sample preparation for down-stream analyses, and flow cytometry. Responsibilities will include: * Generation and maintenance of human tumor organoid lines * Derivation of patient-specific bacterial strains * Support of standard laboratory techniques, including DNA/RNA isolation and FACS * Collecting, handling/processing, and storing of biological samples (e.g. patient feces, blood, tissue) according to standard protocols. * Regular monitoring of animal health and data recording (such as animal weight, behavior, vital signs, tumor growth). * Performing basic procedures on animals (including weighing, oral gavaging, injections, dissection). * Operating sensitive equipment to analyze samples or substances, conducting tests and reporting results. * Recording and analyzing data Your Profile Required: * Education/training as lab technician or technical assistant (BTA, MTA, Biologielaborant:in) or comparable * Strong organizational and time management skills * Reliability and flexibility * Structured, independent, and careful way of working, e.g. ability to implement a variety of laboratory techniques using standard protocols after a thorough training by our scientific staff members * Written and oral communication skills (German and English) Advantageous: * FELASA function A certificate (former FELASA B certificate) * Proven working experience with animal models * Hands-on working experience with cell culture (maintaining cell lines, establishing primary cell cultures) and/or molecular biology techniques (DNA/RNA isolation, PCR) would be an advantage We Offer Excellent framework conditions: state-of-the-art equipment and opportunities for international networking at the highest level 30 days of vacation per year Flexible working hours Remuneration according to TV-L incl. occupational pension plan and capital-forming payments Possibility of part-time work Family-friendly working environment Sustainable travel to work: subsidized Germany job ticket Unleash your full potential: targeted offers for your personal development to further develop your talents Our Corporate Health Management Program offers a holistic approach to your well-being
