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).
