Primary Design Engineer/HV Electrical Engineer em Lisboa, Portugal

1. PURPOSE OF THE ROLE

The Primary Design Engineer is responsible for the primary electrical design of air-insulated (AIS) and gas-insulated (GIS) high-voltage substations and medium-voltage distribution systems serving data centre and industrial clients in the Scandinavian market.

The role focuses on substation physical layout design, primary equipment arrangement, busbar configuration, clearance management, and the integration of primary equipment within the overall substation design. The position works with PRIMTECH and/or Revit as primary design tools and coordinates closely with civil and structural engineering partners for foundations, buildings, and access requirements.

The Primary Design Engineer ensures that primary designs are technically sound, constructable, and aligned with client requirements, grid connection specifications, and applicable standards. The role also supports equipment interface design between HV/MV primary equipment and the secondary, protection, and automation systems.

Note: DCS Norway operates a competence-based resource model. While this job description defines the primary function of the role, individuals are expected to contribute across other engineering and project functions based on their competencies and the needs of the business. This approach supports team flexibility, professional development, and efficient resource utilisation across projects.

2. KEY RESPONSIBILITIES

AIS Substation Design
