Your mission
Hartwig is working to unlock the value of patient data for better care through interactive analytics and database services. One such product is CNXT, a platform that gives researchers and clinicians intuitive access to insights derived from the Hartwig Medical Database. As Junior Software Developer you combine hands-on software development and collaboration with our INFRA team with product ownership of Database services: translating the needs of researchers, clinicians and other stakeholders into a clear product roadmap towards a federated infrastructure.
You report to the Data Lead and work closely with colleagues from data, bioinformatics, governance and infrastructure, as well as with clinicians and pathology experts. You participate in relevant planning and discussion meetings.
