## About the Role

Must Have Technical/Functional Skills

 * 10+ years of hands-on experience with GEV e-terra Energy Management Systems in electric

utility transmission-grid environments.

 * 10+ years of hands-on experience hands-on experience with eTerra Source Database modeling,

Database migration and maintenance. Implementation and migration experience of e-terra source

for more then 5 utilities.

 * Strong understanding of bbranch models, breaker-oriented models, substation topology,

electrical connectivity, network islands, and transformer, generator, and load modeling.

 * Experience supporting EMS network-model changes in production environments.

 * Strong understanding of SCADA measurements and their relationship with EMS network models.

 * Experience troubleshooting EMS database, topology, telemetry, or network-model issues.

 * Working knowledge of transmission-system operations and real-time control-center environments.

 * Strong experience with Linux/Unix and Windows environments, working knowledge of relational

databases and SQL.

 * Strong analytical and troubleshooting skills, with the ability to work directly with utility customers

and cross-functional technical teams.

Roles & Responsibilities

 * We are seeking an experienced EMS Source Database Modeling Expert with strong hands-on

expertise in transmission network modeling, EMS database configuration, model validation, and

production support.

## Description

* The candidate will maintain and enhance the eTerra EMS Source Database and network model,

support model imports and updates, migrate database and model between different version of

e-terra source, resolve database and topology issues, build customer migration changes, and

ensure accurate representation of the transmission system for real-time EMS applications.

 * This highly technical role requires direct experience with eTerra EMS/AEMS environments, utility

transmission systems, SCADA/EMS integration, and network model lifecycle management.

 * Develop, configure, maintain, and validate transmission network models within the EMS Source

Database environment.

 * Model substations, buses, transmission lines, transformers, breakers and disconnect switches,

generators, loads, shunts, capacitor and reactor banks, and measurement and telemetry points.

 * Create and maintain electrical connectivity and topology relationships.

 * Support model changes for new substations, transmission expansions, equipment replacements,

network reconfiguration, and generator additions or retirements.

 * Perform Source Database updates and promote validated model changes across development,

test, and production EMS environments.

 * Validate model consistency between Source Database, real-time database, SCADA, and EMS

applications.

 * Troubleshoot network connectivity errors, incorrect device status, telemetry mapping issues,

topology processing errors, missing or incorrect measurements, model synchronization issues, and

database build or deployment failures.

 * Lead the technical delivery of e-terra source projects assigned and mentor the junior members.

 * Work closely with EMS Applications, SCADA, Power Systems, Database, and Infrastructure
