Principal Specialist Data Modeling & Arch (Operational Technology)

About the Role

Maaden is seeking a Principal Specialist Data Modeling & Arch (Operational Technology) to establish the data modeling and architecture foundation for Operational Technology (OT) and industrial data across its plants, sites, and operational systems in Saudi Arabia. This full-time role is critical for enabling trusted OT analytics by standardizing data representation, governance, and alignment with enterprise IT data products.

Key Responsibilities

• Define enterprise OT data modeling standards for time-series data, events, alarms, assets, tags, measurements, and production contexts.
• Establish canonical OT concepts, including asset hierarchy, location hierarchy, tag naming, measurement definitions, and work order linkage.
• Design scalable data schemas for curated OT layers and reusable OT data products with auditability, lineage, and quality attributes.
• Architect OT-to-IT data alignment patterns that connect operational measurements with enterprise entities for reporting and analytics.
• Define integration rules for tag mapping, unit standardization, reference data, semantic consistency, and cross-site normalization.
• Embed governance-by-design into OT data models, including ownership, metadata, lineage, quality rules, and lifecycle controls.
• Define quality attributes for historian data, including compression, interpolation, quality flags, sampling frequency, and streaming patterns.
• Partner with OT engineering, cybersecurity, data platform, and infrastructure teams to design secure and compliant OT data flows.
• Review solution designs, data models, vendor deliverables, and integration approaches to ensure architectural consistency.
• Provide technical leadership on OT semantics, industrial data architecture, data modeling practices, and data product design.
• Coach engineers, data modelers, platform teams, and solution teams on OT modeling standards and implementation practices.

Qualifications and Experience

• A minimum of 10 years of experience in data modeling and architecture, specifically within Operational Technology (OT) or industrial data environments.
• Demonstrated ability to define and implement enterprise OT data modeling standards for various data types.
• Experience in designing scalable data schemas and ensuring modeling patterns address high-volume industrial data and site variability.
• Proficiency in aligning historians, SCADA/DCS, condition monitoring, maintenance, reliability, and production data with enterprise data products.
• Strong understanding of data governance principles and their application to OT data models, including metadata, lineage, and quality rules.
• Familiarity with industrial cybersecurity requirements and designing secure OT data flows.

Expected Outcomes

• Standard OT data models are defined and consistently adopted across sites, platforms, and industrial systems.
• Assets, tags, events, alarms, measurements, and production contexts are represented consistently for trusted analytics.
• OT-to-IT integration patterns enable reliable cross-domain reporting, performance analysis, and data product development.
• Curated OT layers include clear lineage, quality rules, auditability, and governance controls.
• Site onboarding, tag normalization, unit standardization, and data model reuse are accelerated through practical reference patterns.

Technical Leadership and Mentorship

The Principal Specialist will provide technical leadership in OT semantics and industrial data architecture. This includes coaching engineers and platform teams on modeling standards, leading design reviews for critical OT data initiatives, and building knowledge assets to accelerate consistent OT data architecture delivery.
