- Omics IT and Data Management Core Facility (ODCF)

„Forschen für ein Leben ohne Krebs“ – das ist unsere Aufgabe am Deutschen Krebsforschungszentrum. Wir erforschen, wie Krebs entsteht, erfassen Krebsrisikofaktoren und suchen nach neuen Strategien, die verhindern, dass Menschen an Krebs erkranken. Wir entwickeln neue Methoden, mit denen Tumore präziser diagnostiziert und Krebspatient:innen erfolgreicher behandelt werden können. Jeder Beitrag zählt – ob in der Forschung, in der Administration oder der Infrastruktur. Das macht unsere tägliche Arbeit so bedeutungsvoll und spannend.
For The Core Facility Omics IT and Data Management we are seeking for as soon as possible a
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.
Ihre Aufgaben:
We are looking for a software developer to work at the interface of the two in-house developed open-source applications WESkit (https://gitlab.com/one-touch-pipeline/weskit) and OTP (https://gitlab.com/one-touch-pipeline/otp).

The One-Touch Pipeline (OTP) is a metadata management and workflow orchestration or meta-workflow management system specialized on biological high-throughput data. 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.
