Principal Specialist, Data Modeling & Arch (OT)

About Maaden

Job Purpose

Key Accountabilities

• Define OT data modeling standards for time-series, events, alarms, and asset hierarchies to support operational analytics and reliability use cases.
• Establish canonical OT concepts (asset, tag, measurement, work order linkage, location hierarchy) and ensure consistent adoption across sites and solutions.
• Architect OT-to-IT data alignment patterns that map operational measurements to enterprise entities for cross-domain reporting and performance analysis.
• Ensure OT models account for historian characteristics (high frequency, compression, interpolation, quality flags) and streaming ingestion patterns.
• Design scalable schemas for curated OT layers and OT data products, including auditability, lineage, and quality attributes.
• Partner with OT engineering, cyber/security, and platform teams to ensure secure, segmented, and compliant design for OT data flows.
• Review OT data solution designs and vendor deliverables; provide design authority to resolve modeling trade-offs and ensure long-term maintainability.
• Define reusable patterns for site onboarding and variability handling (naming normalization, tag mapping, unit standardization, reference data).
• Coach engineers and modelers on OT semantics and modeling best practices; lead design reviews for critical OT initiatives.
