Job Requirements

- Core Language, OOP &
- Algorithmic Foundations
- Document, Markup &
- Typesetting Format Expertise

Solid working knowledge of core web and document specifications (HTML5, XML/XSLT, JSON, CSS) and academic publishing formats (PDF Specification, JATS Specification, Unicode/UTF-8/16/32). Exposure to the broader publishing-format landscape —
- MathML, SVG, LaTeX/BibTeX/TeX engines, WIRIS MathType (MTEF), Microsoft Office formats (WordprocessingML, DrawingML, OMML, VML), legacy MS-DOC/CFB formats, bibliography styles and formats, font formats, and extended character encodings — is a strong plus.

- Backend Frameworks, Integration &
- Infrastructure

Spring ecosystem (Framework, Boot, Integration), OpenFeign, and Jackson Core/DataBind, with document-processing libraries (PDFBox, Apache POI) and Docker/AWS S3/GCP Storage for deployment and storage. Experience with Aspose.Words, search/NLP libraries (Apache Lucene, Stanford CoreNLP), messaging systems (Kafka, Artemis JMS/Tibco EMS), and native interop via JNI (FontConfig, FreeType, HarfBuzz, Graphite2, TECKit) is a plus.
