The job

The SCADA Integration Test Engineer is responsible for validating the integration between ETAP's electrical digital twin platform and third-party SCADA and Energy Management Systems. This role focuses on ensuring seamless interoperability through REST APIs, OPC UA, automatic telemetry mapping, and automated model synchronization.

Working closely with product management, software development teams, and external SCADA teams, this engineer will validate end-to-end workflows including electrical network model exchange, telemetry configuration, real-time data acquisition, and system interoperability.

This is a software integration testing role-not a PLC or controls engineering position.

Key responsibilities

• Develop and execute test plans for integrations between ETAP and third-party systems.

• Validate REST API-based exchange of electrical network models and configuration data.

• Verify automated telemetry mapping and synchronization between SCADA and ETAP.

• Test OPC UA communications, real-time data acquisition, and end-to-end system interoperability.

• Collaborate with third-party software teams to troubleshoot interface and integration issues.

• Work with product management and development teams to ensure new integration features meet functional requirements.

• Document defects, reproduce customer issues, and support validation through product release.

Required Skills and Experience:

• 2-5 years of experience testing software integrations, industrial software, or enterprise applications.

• Basic understanding of electrical power systems, including one-line diagrams and common electrical equipment.

• Experience testing REST APIs using tools such as Postman, Swagger, Insomnia, or similar.

• Familiarity with OPC UA communications and industrial data exchange.

• Experience validating multi-system software integrations.

• Strong analytical and troubleshooting skills.

• Excellent communication skills with the ability to coordinate across internal engineering teams and external software vendors.

• U.S. Citizenship or permanent residency/work authorization

Desired skills

• Experience working with SCADA, EMS, ADMS, DMS, or industrial software platforms.

• Knowledge of telemetry, real-time data acquisition, and tag mapping concepts.

• Familiarity with JSON, XML, and data exchange formats.

• Understanding of authentication methods such as OAuth, API keys, and certificates.

• Experience using network analysis tools such as Wireshark or Fiddler.

• Experience with SQL databases and basic scripting (Python, PowerShell, or similar) for test automation.

• Knowledge of IEC 61850, OPC UA, Modbus, or other industrial communication standards.

• Familiarity with issue tracking systems such as Jira.

Salary Range:

65,000.00 - 105,000.00 USD Annual

This pay range represents the minimum and maximum compensation that the position offers, and final compensation can vary within the range depending on work location, job experience, skills, and relevant educational attainment and/or training.
