Configure industrial communication protocols, including PLC communication, Modbus, OPC, Ethernet/IP, and related integration interfaces

Develop control logic using Emerson DeltaV function blocks and related control strategies

Implement sequence control, interlocks, timers, permissives, conditional logic, and process control functions to support safe and reliable system operation

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

Support loop checks, I/O checkout, system testing, commissioning, startup, and turnover activities

Provide on-site troubleshooting, maintenance support, and emergency response for DCS, PLC, communication, alarm, logic, and HMI-related 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 DCS platforms with PLCs, databases, historian systems, and external data systems as needed

Review and interpret P&ID drawings, loop drawings, wiring diagrams, control narratives, cause-and-effect diagrams, and related engineering documentation

Coordinate with engineering, operations, maintenance, commissioning, construction, vendors, and project teams to resolve technical issues and support project execution

Maintain accurate documentation, redlines, configuration records, test results, change logs, and system turnover documentation

Hands-on experience with DCS systems; Emerson DeltaV experience strongly preferred

Experience configuring servers, controllers, EIOC, HMI graphics, system tags, alarms, historian points, and control logic

PLC integration experience, including Ladder Logic and Function Block programming concepts

Knowledge of industrial communication protocols, including Modbus, OPC, Ethernet/IP, PLC communication interfaces, and related network architecture

Strong control logic design experience, including sequences, interlocks, timers, permissives, conditional logic, and process control functions

Ability to read, interpret, and apply P&ID drawings, loop drawings, control narratives, wiring diagrams, and related engineering documentation

Experience supporting loop checks, I/O checkout, system testing, commissioning, startup, SAT/FAT, and system validation activities

Experience with alarm configuration, alarm rationalization, alarm suppression, alarm hysteresis, 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, logic errors, control loops, and field device signals

Ability to collaborate with engineering, operations, maintenance, commissioning, vendors, and project teams

Strong attention to detail, documentation accuracy, and ability to work in high-specification industrial environments

Experience supporting semiconductor, chemical, manufacturing, industrial, high-purity, or critical facility systems

Emerson DeltaV configuration, commissioning, and troubleshooting experience

Experience working with chemical delivery systems, process utilities, UPW, wastewater, gas, exhaust, HVAC controls, or facility monitoring systems

Experience supporting field commissioning, startup, SAT/FAT, loop checks, I/O checkout, and system validation

Knowledge of control system cybersecurity, access control, change management, version control, and system documentation standards

Experience with database integration, historian reporting, dashboard development, and operational data visualization

Experience working in cleanroom, semiconductor fab, construction, or industrial facility environments

Familiarity with instrumentation, transmitters, sensors, valves, analyzers, VFDs, MCCs, and control panels

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