For a large client in the statutory health insurance sector, we are looking for short-term support in analyzing and fixing error patterns in the context of PDF processing using PDFBox.

Specific error patterns are occurring in the ongoing production operation during automated PDF generation, signing, and storage, which need to be resolved:

Transmission Interruptions: Interruptions occur in message transmission during the compilation, signing, and submission of complete PDFs to the input management system.

Display Errors: Isolated faulty blank pages (white pages) are generated in the created document.

Document Display: After editing, supplementing, and re-uploading documents, they can no longer be correctly visualized in the Document Service.

Archiving / Long-term Storage: Submitted PDFs cannot currently be reliably reformatted into the required format for long-term archiving ( Dauerablage).

Conception and implementation of bug fixes in the PDF creation, signing, and conversion process

Ensuring error-free preparation for Document Service and archiving

Execution of unit and integration tests to secure the fixes

Requirements & Skills

Sound, multi-year practical experience with Apache PDFBox (PDF rendering, merging, form fields, signing, conversion)
