About The Position

Architect and Oversee the Ontology/Canonical Data Model (CDM): Lead the end-to-end design of a scalable CDM using Python and Pydantic. Define modeling standards, governance, and interoperability strategies across structured (tabular), unstructured (JSON/API), and MBSE (SysML, LML) data sources. Establish versioning, change control, and extensibility practices for CDM evolution. Help define unified ontology for system of system architecture Lead ETL Architecture and Data Integration: Architect and manage ETL pipelines integrating data from multiple enterprise systems. Oversee data quality, lineage, and validation standards using tools like Pandera. Design for scalability, automation, and operational monitoring. Database and Storage Strategy: Define storage architectures using NoSQL (MongoDB, DynamoDB) and graph databases (Neo4j). Optimize database design for query performance and relationship-heavy data. Guide decisions on indexing, caching, and hybrid storage strategies. Web Interface and API Enablement: Direct the design and development of a web interface for querying and managing CDM data. Lead integration of backend APIs (FastAPI/Django) and front-end frameworks (React/Next.js). Promote best practices in RESTful and GraphQL API design. Model Orchestration and Integration: Lead the integration of the CDM with model orchestration tools such as Ansys ModelCenter, or open-source alternatives. Develop frameworks for orchestrating analytical flows, simulation models, and design studies using standardized interfaces. Ensure interoperability between MBSE environments, analytical models, and enterprise data repositories. Collaborate with systems engineers to implement automated data flows and traceability between system models and analytical results. Support model execution pipelines and configuration management across engineering tools and simulation environments. Develop and champion enterprise and digital data strategies. Align data structures with ontologies and semantic modeling standards (RDF, OWL). Mentor teams on data architecture principles and reusable data design. Collaboration & Mentorship: Serve as the technical authority across cross-functional teams. Mentor mid-level engineers in data modeling, ETL design, and data quality practices. Ensure solutions align with organizational architecture and compliance standards. Using tools such as Git, GitHub, or GitLab to maintain high code quality and consistency. Support the setup, configuration, and maintenance of CI/CD pipelines (e.g., GitHub Actions, Jenkins, Azure DevOps, or GitLab CI) to automate testing, deployment, and integration processes. Utilize collaboration tools like Confluence, Jira, and SharePoint to manage tasking and documentation
