Key Responsibilities

• Configure, build, and maintain SCADA / DCS system architecture, including servers, controllers, EIOC, and related system components
• Design and develop HMI / operator graphic displays to support clear process visibility and operator response
• Create, configure, and manage system tags in accordance with P&ID drawings, project standards, and naming conventions
• Configure industrial communication protocols, including PLC, Modbus, OPC, and related integration interfaces
• Develop control logic using Emerson DeltaV function blocks and related control strategies
• Implement sequence control, interlocks, timers, permissives, and conditional logic to support safe and reliable system operation
• Design integrator-based calculations, conditional logic, and process control functions based on operational requirements
• Configure alarm strategies, including HI, HI-HI, A_ALM, B_ALM, and related alarm parameters
• Implement alarm hysteresis, alarm suppression logic, and OPSUP logic to reduce nuisance alarms and improve operator response
• Provide on-site maintenance support, troubleshooting assistance, and emergency response for control system issues
• Configure historian / INSQL data points, records, trends, and reporting structures
• Develop trend displays, dashboards, reports, and data visualization tools to support operations and engineering teams
• Integrate SCADA systems with databases, historian platforms, and external data systems as needed

Qualifications

• Hands-on experience with SCADA / DCS systems; Emerson DeltaV experience strongly preferred
• Experience configuring servers, controllers, EIOC, HMI graphics, tags, alarms, and control logic
• PLC integration experience, including Ladder Logic and Function Block programming concepts
• Knowledge of industrial communication protocols, including Modbus, OPC, and PLC communication interfaces
• Strong control logic design experience, including sequences, interlocks, timers, permissives, and conditional logic
• Ability to read, interpret, and apply P&ID drawings, loop drawings, and related engineering documentation
• Experience supporting loop checks, system testing, commissioning, and startup activities
• Experience with alarm configuration, alarm rationalization, alarm suppression, and nuisance alarm troubleshooting
• Familiarity with historian systems, INSQL, trend displays, dashboards, and operational reporting tools
• Strong troubleshooting skills related to communication issues, system performance, alarms, and logic errors
• Ability to collaborate with engineering, operations, maintenance, commissioning, and project teams
• Strong attention to detail, documentation accuracy, and ability to work in high-specification industrial environments

Preferred Qualifications

• Experience supporting chemical, semiconductor, manufacturing, industrial, or high-purity facility systems
• Emerson DeltaV configuration and commissioning experience
• Experience working with chemical delivery systems, process utilities, UPW, wastewater, gas, exhaust, or facility control systems
• Experience supporting field commissioning, startup, SAT/FAT, loop checks, and system validation
• Knowledge of control system cybersecurity, access control, change management, and system documentation standards
• Experience with database integration, historian reporting, and dashboard development

Work Environment

This position may require work in industrial, construction, semiconductor, chemical, and facility environments. The role may involve both office-based engineering work and field support, including troubleshooting, commissioning, system validation, and on-site maintenance activities. Candidates should be comfortable working cross-functionally with engineering, operations, construction, and maintenance teams in a fast-paced project environment.
