SCADA Developer – Real-time Status for Electrical Assets

The Mid-Level SCADA Developer is responsible for developing, integrating, and maintaining SCADA systems that monitor real-time performance and status of electrical assets. The role includes creating intuitive HMIs, managing data communications, and ensuring accurate visualization and alarm generation for power distribution networks, substations, and industrial electrical systems.

Key Responsibilities:

• SCADA System Development:
  Design and implement SCADA HMI screens for monitoring real-time data from electrical assets such as transformers, switchgear, circuit breakers, UPS, and energy meters.

• Tag Database and Signal Mapping:
  Develop and maintain SCADA tag databases, ensuring accurate mapping from field devices using protocols like Modbus, DNP3, IEC 61850, and OPC UA.

• Alarm and Event Management:
  Configure and maintain alarms, event logs, and historical trends based on operational thresholds and safety requirements.

• PLC/RTU Interface Development:
  Collaborate with automation and controls engineers to integrate PLCs and RTUs with the SCADA system for real-time status and control capabilities.

• System Optimization and Testing:
  Conduct Factory and Site Acceptance Tests (FAT/SAT), validate SCADA configurations, and optimize system performance.

• Cybersecurity and Access Control:
  Apply security best practices for user authentication, network communication, and data integrity within SCADA platforms.

• Documentation and Compliance:
  Maintain detailed documentation for SCADA architecture, tag definitions, communication protocols, and user manuals.

• Technical Support and Troubleshooting:
  Provide ongoing support for SCADA-related issues, including data discrepancies, communication failures, and HMI performance problems.

Focus Areas:

1. Electrical Asset Visualization:
   Ensure intuitive and reliable graphical representation of voltage, current, breaker status, energy usage, and fault indicators.

2. Advanced Protocol Handling:
   Implement and troubleshoot standard SCADA communication protocols (e.g., Modbus TCP/IP, DNP3, IEC 60870, IEC 61850).

3. Integration with Power Monitoring Systems:
   Integrate energy meters, protection relays, and smart devices with SCADA for real-time monitoring and analytics.

4. System Reliability and Data Accuracy:
   Focus on ensuring high system uptime, accurate tag values, and fast refresh rates across distributed electrical assets.

5. HMI/UX Standards:
   Design consistent and user-friendly HMI interfaces aligned with electrical safety and operation standards (e.g., ISA101, NERC CIP).

Qualifications:

• Bachelor’s Degree or Diploma in Electrical, Instrumentation, Electronics, or Automation Engineering.

• 2–5 years of hands-on experience in SCADA/HMI development, preferably for electrical or power systems.

• Proficiency in one or more SCADA platforms (e.g., Wonderware, GE iFIX, Ignition, Siemens WinCC, Schneider EcoStruxure).

• Strong knowledge of electrical distribution systems and protective devices.

• Familiarity with scripting or programming for automation logic (e.g., VBScript, Python, SQL).

• Experience with FAT/SAT and project documentation.

• Solid troubleshooting, communication, and team collaboration skills.
