Role Overview

The Electrical Engineer – Special Packages manages the design coordination, technical specification compliance, and vendor integration of prefabricated and modular electrical equipment. This includes power skids, e-houses, high-voltage/medium-voltage substations, and integrated automated systems, bridging the gap between engineering design models and factory production.

Key Responsibilities

• Package Management: review vendor drawings, technical data sheets, and schematics for custom, prefabricated electrical modules (e.g., EPODs, containerized switchgear).

• Electrical Design & Modeling: review and optimize single-line diagrams, schematic layouts, and 3D modular coordinate systems using EPLAN, AutoCAD, or Revit.

• System Design Support: oversee calculations for cables, short-circuits, and protection settings in coordination with the Primary/Secondary Substation Protection teams.

• Vendor & Supply Chain Liaison: define technical requirements for procurement, clear technical queries, and ensure specialized vendor packages strictly match data center redundancy standards (N+1, 2N).

• Testing & Inspection: direct and approve Factory Acceptance Testing (FAT) at regional production centers and ensure smooth handovers for Site Acceptance Testing (SAT).

• Standards Compliance: guarantee that all manufactured and integrated elements comply with local and international electrical codes (IEC, IEEE, NEC).

Required Skills and Experience

• Bachelor's or Master's degree in Electrical Engineering or Renewable Energy Systems.

• 3–16 years of experience in heavy industrial engineering, mission-critical infrastructure (data centers), or modular power module production.

• Software competence in EPLAN, ETAP, or Revit BIM environments.

• Strong working familiarity with IEC 61850 protocols (automation/SCADA) and European medium/high-voltage electrical guidelines.

• Professional-level fluency in English is mandatory; professional-level proficiency in Portuguese is highly beneficial for vendor communication.
