Descripción de la vacante

Appnovation, a global digital partner, seeks a Data Architect / Engineer in Medellín to own the data structures behind our knowledge graph platform, define schema and taxonomy, and build resilient ingestion pipelines from SharePoint and the Microsoft stack.

You will influence backend technology choices, establish data quality and governance standards, and collaborate across teams to ensure scalable, secure data models that support evolving content and LLM retrieval quality.

Formación

• Bachelor’s degree in Computer Science or a related field.
• 5+ years of experience in data engineering / architecture roles.
• Deep data modeling across relational and graph paradigms; graph databases (Neo4j) and Postgres/Supabase at scale.
• Strong ETL / data pipeline engineering in Python, including large-scale, incremental, and change-data ingestion.
• Experience with enterprise content ecosystems: SharePoint, ideally Power Platform / Power Automate.
• Knowledge representation, taxonomies/ontologies, and versioned/temporal data.
• Understanding of how data structures feed RAG and LLM retrieval quality.
• SQL proficiency; experience with orchestration tools (e.g., Airflow) and cloud data services.
• Familiarity with data governance, security, and privacy practices.
• Strong documentation and cross-team communication skills.

Responsabilidades

• Define the schema, taxonomy, and graph modeling for the knowledge domains.
• Design how documents, versions, and their machine-readable representations are structured, and how facts evolve over time (including temporal replay).
• Build ingestion/ETL pipelines from enterprise content sources (e.g., SharePoint and the wider Microsoft stack), handling multimodal content.
• Keep the knowledge graph in sync as source documents change frequently.
• Advise on whether the current backend approach (Supabase/Postgres) is the right long-term architecture, and validate ingested content quality with QA.
• Establish data quality, lineage, and governance standards across pipelines.
• Build monitoring, alerting, and error-handling for ingestion jobs.
• Document data models, schemas, and pipeline architecture.
• Optimize pipeline cost, throughput, and reliability over time.
