Dear Sir or Madam,

For an exciting project, we are looking for a Python Data Engineer (IFC-BIM Models, IFCOpenShell, SQL, Databricks/Snowflake/MS Fabric)

Responsibilities

Analysis of the data landscape

Development of data pipelines

Data enrichment and integration

BIM modeling

Quality assurance and documentation

The deployed service provider works with the following technologies, among others:

• Analysis of the provided geodata inventories, mast panels, and existing BIM data structures.
• Analysis of the existing Python script and the current IFC model structure.
• Evaluation of additional infrastructure objects regarding their suitability for data enrichment and BIM modeling.
• Professional coordination of the attributes and modeling parameters to be used.
• Development and further development of data pipelines for automated data acquisition and data processing.
• Integration of information from various data sources.
• Processing of PDF documents, including OCR-supported text recognition and table evaluation.
• Transformation, validation, and cleaning of structured and unstructured data.
• Design and optimization of suitable data models for storing and further processing the data.
• Extraction of relevant information from mast panels.
• Prototypical processing of mast panels, including PDF/image preprocessing, OCR, table recognition, and plausibility checks.
• Extraction of agreed-upon information and assignment to the corresponding objects in the geodata.
• Marking of unrecognized, ambiguous, or implausible information and provision of the enriched data in machine-readable form.
• Ensuring traceable data quality and data integrity.
• Development of procedures for automated plausibility checks of the results.
• Extension and adaptation of existing script components for automated IFC model generation.
• Support in the parametric modeling of overhead line masts and other agreed infrastructure components.
• Integration of enriched data into existing BIM structures.
• Creation and verification of IFC output files regarding technical validity and professional plausibility.
• Performance of quality checks at the data, process, and modeling levels.
• Documentation of data structures, transformation logic, and validation rules.
• Documentation of unresolved data conflicts and special cases.
• Creation of traceable technical documentation of the developed solution.
• Python
• SQL
• IFC / BIM
• IfcOpenShell
• OCR technologies
• GIS data
• Cloud-based data platforms (e.g., Microsoft Fabric, Databricks, or Snowflake)
