📋 Description

• Own and evolve the enterprise reference architecture for secure, scalable OT-to-IT data integration across plant systems, DMZ layers, and the Unified Data Platform • Provide architectural oversight to ensure all integrations align with enterprise design principles and future analytics/AI needs. • Define and govern enterprise standards for OT data integration, including protocols, data models, security, and data quality. • Create reusable onboarding patterns, templates, and playbooks to enable consistent, scalable integration across sites. • Define and operate defensible architectures for OT data egress: OPC UA servers, MQTT/AMQP brokers, data diodes/one-way gateways, and DMZ nodes; prohibit direct control-network access. • Design store-and-forward and buffering strategies to protect control systems and ensure data continuity during outages. • Build/oversee extraction from PHD/PI historians, DCS/PLC/SCADA, LIMS, and lab instruments; implement event frames (batches, phases, grade changes), alarm/event streams, and equipment hierarchies (asset models/AF). • Condition signals (resampling, dead-banding, interpolation, outlier/sensor validation), apply units/calibration metadata, and align to production calendars and ISA-88/95 structures. • Implement observability: freshness, gap detection, tag quality/availability, schema drift; build dashboards and alerts; own on-call runbooks and incident response for OT data flows. • Enforce ISA-62443/ISA-99 controls with Cyber/IT (RBAC, credential vaulting, patching, vulnerability remediation). • Partner with plant controls, process engineering, Reliability/Maintenance, and HSE to prioritize tags, events, and KPIs. • Work with the Manager, Unified Data Platform & AI Engineering to land curated OT data with lineage/DQ and with the Reporting & BI team to certify datasets. • Act as the single thread leader for OT data integration across plants. Drive roadmap and prioritization across OT, IT, and business stakeholders.

🎯 Requirements

• Minimum 7 years' in OT/controls or OT data integration across DCS/PLC/SCADA and historians. • Experience delivering production-grade data pipelines and working with enterprise data platforms (e.g., UDP, Lakehouse) • Hands-on with Honeywell PHD and/or AVEVA PI (interfaces/connectors, AF/asset models, event frames). • Strong knowledge of OPC UA, MQTT (Sparkplug B a plus), Kepware/Ignition or equivalent gateways/brokers. • Proven experience implementing DMZ/broker architectures, firewall rules, certificates, and no control-net reads designs. • Time-series conditioning and event modeling; exposure to ISA-88/95 and batch/phase concepts. • Scripting and data tooling: SQL, Python (validation/utilities), and comfort with Windows Server services. • Familiarity with SAP S/4HANA data touchpoints and LIMS integrations for sample results and quality events. • Working knowledge of security frameworks (ISA/IEC 62443), least-privilege, secrets/cert management.
