OT Data & Integration Lead

AdvanSix; United States; On-site; USD 118,800 - 178,200; Full time

Job summary

AdvanSix seeks an OT Data Integration Lead to design and operate secure, governed data flows from control systems into the UDP. You will bridge OT and IT, coordinating with plant controls, Cyber/IT, UDP engineering, and system owners to deliver near-real-time analytics-ready data.

Responsibilities include owning enterprise reference architecture, defining data standards, and creating onboarding playbooks for scalable integration across sites.

Qualifications

• Minimum 7 years in OT/controls or OT data integration.
• Experience delivering production-grade data pipelines and enterprise data platforms.
• Hands-on with Honeywell PHD and/or AVEVA PI interfaces/connectors.
• Strong knowledge of OPC UA, MQTT, Kepware/Ignition gateways/brokers.
• Proven experience implementing DMZ/broker architectures and secure designs.
• Time-series conditioning and event modeling; ISA-88/95 exposure.

Responsibilities

• Own and evolve the enterprise reference architecture for secure OT-to-IT data integration.
• Provide architectural oversight to align integrations with enterprise design principles.
• Define and govern enterprise standards for OT data integration, including data models and security.
• Create reusable onboarding patterns and playbooks for scalable integration across sites.
• Define OT data egress architectures and prohibit direct control-network access.
• Design store-and-forward and buffering strategies to protect control systems.
• Standardize onboarding patterns for new plants and zones.
• Publish raw/event data schemas to the UDP for analytics readiness.
• Lead OT data integration roadmap across plants with IT and business stakeholders.

Job description

The OT Data Integration Lead designs and operates the secure, governed flow of plant data from control and manufacturing systems into AdvanSix’s Unified Data Platform (UDP). This role bridges Operations Technology (OT) and Information Technology (IT)—covering historians so that Operations, Reliability/Maintenance, HSE, Quality, Supply Chain, and Engineering have trustworthy, near-real-time data for analytics, ML, and agentic automation. You will set patterns, lead integrations, and coordinate closely with plant controls teams, Cyber/IT, the UDP engineering team, and system owners.

Mission

Deliver safe, reliable, and observable OT-to-enterprise data connectivity that:

• Decouples control networks from analytics (no direct control-net reads) using broker/DMZ patterns,
• Produces high-quality, well-modeled time-series and events (assets, batches, phases, alarms) for the UDL, and
• Meets security, compliance, and uptime requirements without impacting production.

Core responsibilities

• 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.
• Standardize onboarding patterns for new plants/units (network zones, firewall rules, certificates, endpoint hardening).

Time-Series & Event Modeling

• 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.
• Publish contracted schemas into the UDP (landing → curated → semantic) for consumption by Power BI, APIs, and ML.
• Design reusable industrial data products (assets, batches, KPIs). Enable semantic layer readiness for analytics and AI workloads

Reliability, Security & Compliance

• 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).
• Lead and document MOC/change control, outage coordination, and pre-/post-validation with plant teams.
• Define SLAs/SLOs for OT data pipelines. Implement automated data quality scoring and lineage tracking
• 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.
• Guide vendors (historians/SCADA integrators) with clear DoD, acceptance tests, and knowledge-transfer milestones.
• Act as the single thread leader for OT data integration across plants. Drive roadmap and prioritization across OT, IT, and business stakeholders

Required qualifications

• 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.

Preferred qualifications

• Experience with Azure OT ingestion patterns: IoT Edge, Event Hubs, Kafka, Databricks/Fabric streaming.
• PI AF/EF or PHD equivalent asset/event modeling at enterprise scale.
• Knowledge of alarm rationalization (ISA-18.2), sensor validation, calibration workflows.
• Exposure to HSE/EMIS systems and environmental reporting data.
• Certifications: ISA-62443, CCNA-Industrial, or vendor historian credentials.

The base salary range for this role is $118,800 to $178,200 annually.
