The Role of Principal Specialist, Data Modeling & Architecture (OT)

This full-time position, based in Riyadh, serves as the architectural authority for modeling operational technology (OT) and industrial data. The Principal Specialist ensures consistent representation of assets, events, measurements, and production contexts across various plants, sites, and operational systems. The role is critical for enabling trusted OT analytics by defining standard models that align historians, SCADA/DCS, condition monitoring, and maintenance data with enterprise IT data products. It also addresses OT constraints such as high-volume time-series data, latency, site variability, and intermittent connectivity through practical modeling patterns, semantic consistency, and governance-by-design for OT-to-IT integration.

Key Responsibilities

• 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.

Qualifications

• Bachelor’s degree in Computer Science/Engineering, Industrial Engineering, Data Engineering, or a related field.
• A Master’s degree is preferred.
• Background in OT/industrial systems is considered an advantage.

Required Experience

• 10 to 15 years of experience in data modeling and architecture, with demonstrated exposure to OT/industrial data landscapes.
• Experience working with historians, industrial protocols/systems, and integrating OT data into enterprise analytics platforms.
