Deutsches Krebsforschungszentrum (DKFZ) Software Developer 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 Reference number: 2025 0106 Heidelberg Full time Omics IT and Data Management Core Facility (ODCF) 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. Your Tasks 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 ). WESkit is a Workflow Execution Service ( https://github.com/ga4gh/workflow execution service schemas ) and submits bioinformatic workflows implemented with Snakemake or Nextflow into our high throughput cluster. 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. Your main activities will be: Work in a small team on making WESkit production ready Communicate with and support the OTP team in WESkit''s installation, interfaces, and operation Your Profile The following skills are particularly important for this position: Python, including typed Python using Mypy, Celery, Flask Teamwork and communication, including working in a distributed team Agile software development, e.g. SCRUM Container technologies, in particular Docker and Singularity The following topics are relevant and experience in them is considered a bonus: Software design and architecture Object oriented design patterns Building robust, scalable, usable, production quality software Workflow management systems, in particular Snakemake and Nextflow High throughput cluster systems, in particular IBM LSF and SLURM Kubernet
