Industrial OT Data Architect & Modeling Lead

Maaden Saudi Arabian Mining Company; Saudi Arabia; On-site; SAR 300,000 - 550,000; Full time

Job summary

Maaden Saudi Arabian Mining Company seeks a senior OT data architect to establish data modeling standards and architecture for operational technology across plants and sites. You will define canonical OT concepts, design scalable schemas, and drive OT-to-IT alignment with a focus on governance, security, and data product quality.

You will lead cross-site data initiatives, ensure high-volume data handling, and foster actionable analytics through robust data models and secure data flows.

Qualifications

• Bachelor’s Degree in Computer Science, Computer Engineering, Data Engineering, Industrial Engineering, Information Systems, or related field.
• Master’s Degree is preferred.
• Minimum 10 years of progressive experience in data modeling, data architecture, data engineering, industrial data platforms, or OT/IT integration.
• Strong exposure to OT data sources such as historians, SCADA/DCS, condition monitoring, maintenance, reliability, and production systems.
• Experience defining enterprise data models, data standards, semantic layers, governance controls, and scalable data product architectures.

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.
• Ensure modeling patterns address high-volume industrial data, latency requirements, site variability, and intermittent connectivity.
• Architect OT-to-IT data alignment patterns that connect operational measurements with enterprise entities for reporting and analytics.
• Align historians, SCADA/DCS, condition monitoring, maintenance, reliability, and production data with enterprise data products.
• Define integration rules for tag mapping, unit standardization, reference data, semantic consistency, and cross-site normalization.
• Support cross-domain analytics by ensuring OT data is usable for reliability, production performance, safety, sustainability, and cost insights.
• 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.
• Establish reusable governance patterns for site onboarding, data standardization, naming conventions, and master/reference data alignment.
• Ensure OT data products are traceable, reliable, maintainable, and aligned with platform architecture standards.
• Partner with OT engineering, cybersecurity, data platform, and infrastructure teams to design secure and compliant OT data flows.
• Ensure OT data architecture respects segmentation, access control, operational resilience, and industrial cybersecurity requirements.
• Review solution designs, data models, vendor deliverables, and integration approaches to ensure architectural consistency.
• Resolve modeling trade-offs and guide design decisions to support long‑term scalability, maintainability, and operational reliability.
• 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.
• Lead design reviews for critical OT data initiatives and ensure decisions are documented and reusable across sites.
• Build knowledge assets, standards, templates, and reference patterns to accelerate consistent OT data architecture delivery.
