• Experience with OSIsoft PI / AVEVA PI, including PI AF asset framework configuration and PI Web API.
• Experience with LIMS integration, such as LabWare, Uncountable, or LabVantage.
• Familiarity with GAMP 5, 21 CFR Part 11, or nuclear quality (NQA-1) requirements for control-system validation.
• Experience with SQL and Python scripting for data processing, report generation, or control-system testing automation.
• Exposure to IEC 62443 OT cybersecurity standards and secure network architecture for industrial control systems.
• Experience with REST API development or consumption for system integration.

Responsibilities

• Develop and maintain PLC and DCS programs using major platforms and IEC 61131-3 programming languages.
• Develop and configure SCADA applications, including tag databases, communication drivers, scripting, and alarm configuration.
• Design local-panel and supervisory SCADA HMI displays in accordance with ISA-101 and High-Performance HMI principles.
• Develop ISA-88 batch control sequences, including phase logic, unit procedures, and recipe management, and monitor batch execution and progress.
• Configure and manage alarm systems in accordance with ISA-18.2, including setpoints, priorities, suppression logic, and KPI monitoring.
• Configure and commission safety instrumented functions on SIS platforms in accordance with IEC 61511.
• Configure plant historian systems, build process-data dashboards and reports, and support ISA-95 data exchange with MES, ERP, or LIMS systems.
• Tune PID and advanced regulatory control loops; commission, calibrate, and document instrumentation.
• Own instrument engineering scope, including sizing and specifying field devices, developing instrument indexes and hook-up drawings, and performing hazardous-area classification for new and modified installations.
• Review instrument specifications prepared by junior engineers and contractors.
• Implement industrial communication protocols and configure interfaces among PLCs, SCADA, historians, and third-party systems.
• Support OT network cybersecurity hardening in accordance with IEC 62443 or NIST SP 800-82.
• Prepare and execute control-system FAT, SAT, and commissioning plans; perform loop checks, calibration verification, interlock testing, and regulatory-loop tuning.
• Maintain engineering documentation, including functional specifications, control narratives, I/O lists, cause-and-effect matrices, tag lists, and as-built records.
• Diagnose and resolve control-system faults, perform root-cause analysis, and document corrective actions.
• Provide technical direction to contractors and consultants on I&C scope, and review and redline deliverables for compliance with project standards and nuclear quality requirements.
• Mentor junior engineers and provide technical leadership for complex projects.
