About The Position

AdvanSix plays a critical role in global supply chains, innovating and delivering essential products for our customers in a wide variety of end markets and applications that touch people’s lives, such as building and construction, fertilizers, plastics, solvents, packaging, paints, coatings, adhesives, and electronics. Our reliable and sustainable supply of quality products emerges from the vertically integrated value chain of our three U.S. based manufacturing facilities. AdvanSix strives to deliver best-in-class customer experiences and differentiated products in the industries of nylon solutions, chemical intermediates, and plant nutrients, guided by our core values of Safety, Integrity, Accountability and Respect. 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 Layer (UDL). This role bridges Operations Technology (OT) and Information Technology (IT) and plant IoT — so that plant operations 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 UDL engineering team, and system owners. This role will report into the Manager, Unified Data Platform & AI Engineering.

Requirements

• Minimum 7 years' experience in OT/controls or OT data integration across DCS/PLC/SCADA and historians.
• 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.

Nice To Haves

• 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.

Responsibilities

• Define and operate defensible architectures for OT data egress.
• 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).
• 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, apply units/calibration metadata, and align to production calendars and ISA-88/95 structures.
• Publish contracted schemas into the UDL for consumption by Power BI, APIs, and ML.
• 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.
• Partner with plant controls, process engineering, Reliability/Maintenance, and HSE to prioritize tags, events, and KPIs.
• Work with manager 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.
