- Ensure SAS designs meet data center reliability and redundancy requirements.
- Prepare SAS specifications and functional descriptions.
- Support integration of SAS with data center monitoring and management systems.
IEC 61850 Engineering
- Configure IEC 61850 communication systems, including SCL file development.
- Develop GOOSE messaging configurations and communication mapping.
- Support integration of protection relays and control devices within the IEC 61850 framework.
- Prepare engineering documentation related to communication systems.
- Support testing and validation of communication configurations.
SCADA Integration
- Support integration of substations with client and utility SCADA systems.
- Develop signal lists and communication mapping.
- Coordinate SCADA interfaces with control systems.
- Support commissioning of SCADA communication.
- Prepare documentation related to control and monitoring systems.
IED Configuration & Communication
- Configure intelligent electronic devices (IEDs) for communication within SAS.
- Programme RTUs and gateways for SCADA and remote communication.
- Support IED integration with protection relay settings provided by Protection Engineers.
- Ensure communication protocols are correctly configured and tested.
Cybersecurity & OT Systems
- Support cybersecurity considerations for substation OT networks in accordance with IEC 62351 and client requirements.
- Contribute to network security architecture for substation automation systems.
- Ensure cybersecurity requirements are integrated into SAS design and documentation.
Testing, Commissioning & Documentation
- Support SAS testing and validation activities, including FAT and SAT.
- Prepare test plans and procedures for substation automation systems.
- Prepare and maintain engineering documentation for SAS and SCADA systems.
- Support preparation of as-built documentation.
- Participate in engineering design reviews.
Required Qualifications and Competencies:
- Bachelor's or Master's degree in Electrical Engineering, Automation, or related discipline.
- Minimum 5 years of experience in substation automation or SCADA engineering.
- Experience with IEC 61850 configuration and engineering.
- Experience working with SCADA and automation systems.
- Experience in HV or MV substation projects.
- Experience with data center or industrial automation projects is a plus.
- Proficiency with IEC 61850 tools (IET600, SCD editors, SCL configuration).
- Experience with relay vendor communication tools: PCM600 (ABB), Digsi 5 (Siemens), MiCOM S1 (Schneider Electric).
- Knowledge of SCADA platforms and communication protocols.
- Understanding of substation automation system architecture and design.
- Familiarity with network security principles for OT environments (IEC 62351).
- Proficiency with EPLAN and AutoCAD for SAS documentation.
- Familiarity with Nordic TSO standards is considered an advantage.
- Excellent verbal and written communication in English (Portuguese is considered a plus).
- EU citizenship preferred to facilitate site visits across Scandinavia.
