Control System Engineer

We are seeking a Control Systems Engineer with a strong foundation in electrical engineering and hands-on experience in industrial automation systems. This role is responsible for the design, programming, commissioning, and troubleshooting of PLC-based control systems, industrial networks, and associated instrumentation across manufacturing, water/wastewater, or process environments.

The ideal candidate combines solid engineering fundamentals with practical field experience in diagnosing real-world issues such as communication faults, drive behavior, and system integration challenges.

• Design and develop control systems using PLC platforms such as:
• Rockwell Automation (ControlLogix, CompactLogix)
• AutomationDirect Productivity series
• Develop I/O layouts, panel designs, and electrical schematics
• Size and specify components (power supplies, transformers, breakers, relays, etc.)
• Ensure compliance with NEC, UL, and industry standards

• Develop PLC programs using:
• Ladder Logic
• Structured Text
• Function Block (e.g., PIDE)
• Configure and troubleshoot:
• EtherNet/IP communications (explicit/implicit messaging)
• Modbus TCP/RTU devices
• Integrate third-party devices (VFDs, flow meters, UPS systems, instrumentation)
• Configure HMIs and SCADA systems (e.g., Ignition)

• Diagnose and resolve issues such as:
• PLC I/O faults and module dropouts
• Industrial network communication errors (e.g., “Invalid Originator to Target”)
• VFD faults and abnormal output conditions
• Power quality and grounding issues
• Perform system startup, loop checks, and functional testing
• Support field technicians and operators during commissioning

• Configure and maintain industrial networks including:
• Managed switches and routers (e.g., VLANs, NAT, VPNs)
• Remote access solutions (OpenVPN, secure tunneling)
• Troubleshoot network reliability issues in control environments

• Develop SCADA applications and reporting tools using platforms like:
• Inductive Automation Ignition
• Create tag structures, expressions, and reporting logic
• Implement data logging, alarms, and daily/shift reporting (e.g., flow totals, runtime)

• Create and maintain:
• Control narratives
• I/O lists
• Network architecture diagrams
• As-built documentation
• Provide technical support and training to operators and maintenance staff

• Bachelor’s degree in Electrical Engineering or closely related field
• 3 years of experience in industrial automation or controls engineering
• Strong understanding of:
• AC/DC circuits and control power systems (e.g., 24VDC, 120VAC)
• Motor control and VFD operation
• Industrial communication protocols (EtherNet/IP, Modbus)

• Experience with:
• Rockwell Studio 5000 / RSLogix
• Ignition SCADA platform
• Industrial instrumentation (flow meters, level sensors, pressure transmitters)
• Familiarity with:
• NEC code for control panels and transformer sizing
• Hazardous location classifications (e.g., Class I Div 2)
• Experience in water/wastewater, oil & gas, or manufacturing environments
• Networking knowledge (routing, NAT, VPN configuration)

• Strong troubleshooting and root cause analysis
• Ability to interpret electrical schematics and P&IDs
• Hands-on commissioning experience
• Clear technical communication (written and verbal)
• Ability to work independently in field environments

• Combination of office engineering work and field work
• Travel to job sites for commissioning and troubleshooting (as required)
• Occasional on-call or off-hours support during startup phases

• Troubleshooting EtherNet/IP communication between PLCs and VFDs
• Designing a control panel with proper transformer sizing and protection
• Diagnosing abnormal VFD output voltages and grounding issues
• Implementing Ignition reports for daily flow totals and system performance
• Setting up secure remote access to PLC systems via VPN-enabled routers
