What are our benefits?
• You will have flexible working hours and remote work policies.
• You will have access to a flexible compensation plan.
• We give you the opportunity to enjoy a physical and emotional well-being program.
• Our commitment is to provide you with job stability and long-term projects.

• We promote equal opportunities, diversity, and inclusion for all people, and we are certified as a Family-Responsible Entity (efr).
Every Data Center we develop involves highly demanding technical decisions behind it: how to guarantee service continuity, how to ensure true redundancy, how to integrate electrical systems with architecture, mechanics, or control without any margin for error.
And that is where the electrical team plays a key role.
To strengthen our team, we are looking to bring in a Senior Electrical Engineer with experience in the design of electrical systems for Data Centers or high-criticality environments, who wants to keep growing professionally in complex projects with real impact.
What will your responsibilities be?
How will you do it?
You will be part of a team made up of professionals with diverse backgrounds and varied experience, which will allow you to develop an interesting and enriching perspective. At the same time, we have a Development Program focused on mentoring roles, so that in the short/medium term, you can carry out your duties and lead your projects with autonomy.
Electrical design for Data Centers
You will take part in developing the design of critical electrical infrastructures for medium and low voltage, including distribution architectures, UPS systems, backup power generation, electrical switchboards, and critical distribution systems (PDUs, RPPs, STSs).
You will contribute to defining design criteria, redundancy strategies, availability, maintainability, and energy efficiency, as well as integration with other disciplines.
Electrical calculations and studies: You will develop and review electrical calculations associated with the design: load balance, equipment sizing, short-circuit studies, protection coordination, voltage drop, harmonic analysis, and grounding systems.
You will ensure the technical consistency of the system and compliance with service continuity criteria.
Development of technical documentation
You will prepare and review project technical documentation: single-line diagrams, electrical schematics, specifications, data sheets, load lists, drawings, and technical reports.
You will also take part in the technical review of documentation from suppliers and contractors.
Technical and multidisciplinary coordination: You will collaborate with architecture, mechanical, telecommunications, control/BMS, civil, structural, and commissioning teams, ensuring the correct integration of the electrical design within the Data Center as a whole.
You will attend technical meetings with the client and other project stakeholders.
Technical management of electrical work packages: You may take on responsibility for electrical work packages within national and international projects, ensuring compliance with scope, schedule, quality, and client requirements.
Depending on your experience, you may coordinate other engineers, review deliverables, and provide technical support.
Standards and regulations: You will ensure that designs comply with applicable regulations and the specific standards of the Data Center sector (IEC / EN, REBT, TIA-942, Uptime Institute, NFPA / NEC), adapting to the requirements of each client and project.
