„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.

For The Core Facility Omics IT and Data Management we are seeking for as soon as possible a Software Developer.

The Omics IT and Data Management Core Facility at the German Cancer Research Center (DKFZ) provides comprehensive support for large-scale omics projects, including secure data storage, high-throughput analysis, and tailored software solutions. By collaborating closely with researchers, we ensure robust bioinformatics pipelines and efficient workflows to drive breakthroughs in cancer research. To achieve this we develop custom software for data management and workflow execution.

Our short-term goal is to let OTP submit and manage all workflow executions via WESkit. The long-term goal is to develop WESkit into a standalone workflow execution service for the research community, including its interaction with other GA4GH standards (https://www.ga4gh.org/our-products/#), such as TES, TRS, or DRS.
