Job Summary - Telecommunication & Control Field Engineer This position is responsible for the implementation, analysis, testing, operation and maintenance of advanced communication and control systems that support the reliable operation of electric utility infrastructure. Telecomm Field Engineers work hands-on in the field with technologies such as fiber optics, microwave radio systems, RF systems, RF (900Mhz) and fiber optic Field Area Networks (FANs), MPLS-TP nodes, SCADA systems, and carrier-grade protection systems. While not design engineers, Telecomm Field Engineers collaborate closely with design teams to ensure systems meet operational needs and performance standards. Principal Duties and Responsibilities Telecommunication & Control Field Engineer 1 / Specialist 1 / Associate Engineer Assists in the installation, testing, and troubleshooting of communication systems including fiber optics, microwave radios, RF networks, and SCADA components. Supports configuration and validation of MPLS-TP nodes and network devices operating at speeds up to 100 Gbps. Participates in field verification of carrier protection systems and remote terminal units (RTUs). Aids in the analysis of system faults and communication failures to identify root causes and recommend corrective actions. Works with design engineers to ensure field implementations align with system requirements and standards. Maintains documentation and records for system configurations, test results, and maintenance activities. Telecommunication & Control Field Engineer 2 / Specialist 2 Independently performs testing, commissioning, and troubleshooting of complex communication and SCADA systems. Develops and maintains RTU configurations, network configurations and routing schemes for SCADA, MPLS-TP, and FAN systems. Analyzes system performance metrics and recommends improvements to enhance reliability and throughput. Provides technical support for field personnel and assists in training on new systems and technologies. Conducts peer reviews of junior engineers' work and contributes to continuous improvement initiatives. Telecommunication & Control Field Engineer 3 / Specialist 3 Leads field implementation of new communication technologies and SCADA system upgrades. Develops and tests advanced RF, fiber optic, and SCADA communication schemes for utility applications. Serves as a subject matter expert on microwave radio systems, MPLS-TP architecture, SCADA protocols, and carrier protection systems. Participates in the development of standards and best practices for communication system deployment and maintenance. Supports compliance with industry standards and regulatory requirements (e.g., NERC, CIP, IEEE). R&D - Engages in industry forums and technical groups to stay current with emerging technologies and practices. Senior Engineer / Senior Specialist Provides technical leadership and mentorship to engineering staff. Oversees complex projects involving multi-technology communication and SCADA systems and ensures high-quality execution by the rest of the team. Represents the group in cross-functional meetings and external engagements. Helps develop and approve future projects, design templates, and hardware used in current and future designs. Identifies and implements process improvements to enhance system reliability, efficiency, and maintainability. Leads strategic initiatives to modernize communication infrastructure and integrate new technologies. The preceding description is not designed to be a complete list of all duties and responsibilities required of the position. As a public utility, NiSource is required to provide continuous service to customers at all times. To ensure we fulfill that obligation, employees may be required to work outside their normal work hours and perform tasks outside of their normal responsibilities in support of emergency operations.
