MUST HAVES

   • Bachelor's Degree in a technical field

   • 5+ years of experience working in data modeling

   • Skilled in designing conceptual, logical and physical data models to accurately represent data structures

   • Proven track record in driving source systems, generating models, and supporting the business needs from a data perspective

   • Proficient with data modeling tools such as erwin Data Modeler, ER/Studio, or IBM Data Architect

   • 2+ years of hands-on experience with Ontology Design and Implementation

   • Skilled in creating semantic data models, reasoning engines, validation rules, developing semantic metadate and tagging strategies, and maintaining knowledge graphs

   • Familiarity with Ontology tools like Protégé, TopBraid Composer, and FluentEditor

   • Proficient in Ontology languages such as OWL (Web Ontology Language), RDF (Resource Description Framework), and SHACL (Shapes Constraint Language)

   • Strong experience in AWS Cloud, Python, and SQL

   • Demonstrated ability to articulate ideas clearly, effectively engage with stakeholders, and communicate the process and benefits of ontology creation

PLUSSES

   • Hands-on experience with AWS Glue

   • 3+ years of experience with Spark, Kafka or other big data processing frameworks

   • Prior experience with AWS GovCloud, Data Catalogue or AWS RedShift

   • Experience in the aviation industry or other regulated industries

DAY TO DAY

   • Design and implement ontologies that represent manufacturing processes, part configurations, supply chain hierarchies, logistics, quality events, and compliance frameworks.

   • Collaborate with domain experts across engineering, quality, logistics, and IT to formalize vocabulary, terminology, and relationships using OWL, RDF, SHACL, and similar standards.

   • Develop and maintain knowledge graphs that integrate data from MES, ERP, PLM, QMS, and IoT sources.

   • Establish semantic data models to support digital twin, root cause analysis, predictive quality, and sustainability efforts.

   • Support interoperability between systems and across tiers of suppliers by aligning with standards such as ISO 8000, QIF, ISO 10303 (STEP), and others.

   • Implement and tune reasoning engines and validation rules to infer product dependencies, identify anomalies, and ensure data integrity.

   • Drive the development of semantic metadata and tagging strategies to power advanced search, lineage tracing, and knowledge reuse.

   • Align ontological structures with enterprise data strategies and digital engineering initiatives, including model-based systems engineering (MBSE).

   • Contribute to knowledge governance and ontology lifecycle management processes.
