Data Developer - nexuzhealth

Software & Analysis, Data
Professional, Freelancer

For nexuzhealth nv's electronic patient record, there are several applications that generate a large flow of data. These applications are used both by internal healthcare providers (KWS, MOAPR, mobile companion apps, ...) and referrers (mynexuzhealthpro) and patients (mynexuzhealth). Almost half of Flemish hospitals use these applications in their daily operations. Maintenance of the existing applications and new developments are carried out entirely in-house by a large team of developers who use a broad technology stack from Java and Go, SQL and Cloud Spanner, Swing and Angular via fat, mobile and kubernetes environments. Within this development team, the data team specialises in making data insightful across functional domains. To this end, they develop both general solutions for data extraction and reporting as well as answers to specific research questions. Due to the ever-increasing demand for further data accessibility, we are looking to greatly expand this team in the short term. The employment is between 80 and 100%.

  • You will help set up general reporting environments and tools to make the data sources widely accessible. You will do this both with existing on premise solutions such as Sybase ASE and Microsoft SQL Server and with cloud technologies to be explored such as Google BigQuery, Data Studio and the associated connectors or 3rd party reporting tools.
  • You analyse and help assess incoming project requests for technical feasibility, functional completeness as well as the corresponding planning and roadmap.

  • You have excellent knowledge of SQL, Java and OO design, including design patterns.
  • Experience with or knowledge of FHIR, Go and Python are a plus.
