Electrical Engineer (LV&MV)

Location: Sines or Remote

About the job:

The Electrical Engineer (LV & MV) supports the design, implementation, and operation of electrical systems that power our large-scale data centers. Reporting to the Senior Electrical Engineer, this role is critical in ensuring electrical safety, reliability, and efficiency throughout the project lifecycle - from concept and design to commissioning and operation.

This function works closely with design consultants, contractors, and internal teams to deliver best-in-class electrical systems across Low Voltage (LV) and Medium Voltage (MV) networks (non-proficient High Voltage support may also be required to support the team). 

Cross functional activities are required in three main domains: “Datacenter Core Systems”, “Buildings” and “Substations”.

Responsibilities:

Design & Engineering

• Support the design, review, and validation of electrical systems for data centers, covering LV,MV and HV distribution networks (proficient in LV and MV)..
• Participate in the development of single-line diagrams (SLDs), cable routing, and protection schemes.
• Collaborate with design consultants and vendors to ensure technical specifications meet project and operational requirements.
• Assist in defining design standards, technical specifications, and best practices for scalability and energy efficiency.

Project Execution

• Provide technical input and supervision during procurement, installation, and commissioning phases.
• Review contractor designs, material submittals, and method statements for compliance with design intent and regulations.
• Conduct site inspections and testing (FAT, SAT, and commissioning).
• Support troubleshooting and resolution of electrical issues during construction and operation.

Operations & Maintenance Support

• Assist in the transition from construction to operations, including documentation and training handovers.
• Contribute to the development of maintenance procedures and electrical safety protocols.
• Participate in root-cause analyses for electrical incidents or performance issues.
• Ensure all work complies with IEC standards, local regulations, and company safety policies.

Cross-functional Collaboration

• Work closely with mechanical, civil, and controls engineering teams to ensure systems integration and performance optimization.
• Support sustainability initiatives, including power usage effectiveness (PUE) optimization and renewable integration.
• Liaise with utility providers and grid operators as needed for MV connections and upgrades.

Preferred Qualifications & Skills:

• Degree in Electrical Engineering or related field.
• 3–6 years of relevant experience in electrical design, construction, or maintenance, ideally in data centers, industrial, or energy infrastructure environments.
• Solid knowledge of LV & MV distribution systems, switchgear, transformers, and protection systems.
• Familiarity with IEC standards and Portuguese electrical regulations.
• Proficiency with electrical design tools (e.g., AutoCAD, EPLAN, ETAP, or similar).
• Strong command of English and Portuguese (written and spoken).
